 yeah i compiled your code with the same outcome just so you are
 aware.

just to make sure i understood this correctly: the problem of not
seeing anything is related to videoAVFoundation not being ready yet,
and not to some obscure issue with the window handling, right?
i mean: you *do* see a white rectangle, and when you compile the
videoTEST plugin, it does create noise?

btw, is it intentional that you have disabled quicktime4linux support

i would highly appreciate to put code that potentially effects

all files outside plugins/*AVFoundation/ (namely configure.ac,

ok, thanks.

i've manually merged in this branch (completely leaving out the
build\win-vc2010e\ folder).
i've also excluded the PDF and it's ODT and instead converted it into
a wiki-page [1]mainly because i prefer having text as text rather

no not currently.
i do have plans however for a replacement for [pix_imageInPlace] and
[pix_multiimage] using [pix_buffer].
probably an object that uploads an entire [pix_buffer] to textures.
 
 and another question - is there currently a way to convert a raw
 list of numbers into an image, as a pix_set object does, but store
 it in a buffer along with other images?

[pix_set]+[pix_buffer]?

 Hi,
 
 I built GEM on Windows with Visual C++ 2010 Express under Windows
 7. I made a how-to pdf with a step-by-step.

this is very welcome.?!

 I have a working Gem.dll and several extras.

cool.

 I managed to build filmDS by making some changes in the code
 (adding a lacking qedit.h and changing #include order) but this
 could have broken other builds.

hmm, weird (i mean: why does it work on the original build?)

 
 I also have a question concerning Gem's dependencies. I need to put
 some dll (freetype6.dll, ftgl.dll, pthreadVC2.dll and zlib/dll)
 beside Gem.dll.

iirc, i build a static library of FTGL and link to that.
this should fix the freetype6.dll/ftgl.dll issue (maybe zlib.dll as well).
as for pthreadVC2.dll: isn't this shipped with Pd-vanilla?

 
 I build Gem mainly to be able to build pix_opencv on Windows and I
 don't try IT a lot. So if somebody have time to test this on
 Windows, I'll be happy to make an archive with binaries. For now,
 there is a new folder under the build\ folder in my github 
 Gem/vce2010 branch. https://github.com/avilleret/Gem.git

no, this shouldn't be a problem.
C-binaries are compatible between different compilers, C++-binaries
are not.
Pd only has a C-interface, so there shouldn't be a problem.
otoh, Gem's plugins are all C++, that's the reason why Direct*-plugins
don't work with a mingw build.

 
 I also managed to produce a Gem.dll form Microsoft Visual C++ 2010 
 Express and this time Gem loads in pd-vanilla 0.45.2
 
 and it seems to work !

cool.

 
 but i am wondering if i am doing right : Gem claims that some dll 
 are missing and I added them directly to the Windows\System32 
 folder should I include them in the Visual Project instead ?

you should be able to put them besides Gem.dll.
if that doesn't work, put them besides pd.exe.
Windows\System32 is a *bad* place.

yes.

GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS is a label, that can be used to
query the maximum number of combined texture image units. it is not

 Now that it's clarified that this is a bug, not a feature. It 
 should be evaluated why it behaves differently and if it is worth 
 it to keep the changes or we can go back to the original.

yes.

i haven#t fully reviewed the new algorithm, but the main motivation
(for me to include it) was that it supports a dynamic number of blobs
(rather than a fixed maximum number). i think that *this* behaviour is
desirable and i don't really see how it would break compatibility.
(and if it does break compatibility, i think that it can easily be
fixed: e.g. by explicitely specifying a maximum-number-of-blobs (using
the argument) it will become static/fixed, and if you don't specify no
number it is dynamic).

the other thing is how blobs are detected. here there might be some
incompatibility, which ought to be investigated and fixed.

 What can i do, to help fixing it? I didn't quite understand what 
 you
meant at the IRC.

isolating the problem to a static patch (static in the sense that it
doesn't require any moving images), so we can do: if i feed imageA
into the object, the old version will output blob1@x1,y1 blob2@x2,y2
whereas the new one will output blob1@x1,y1 blob2@x3,y3 blob3@x4,y4

finally, we have to make sure that the problem is not simply related
to a wrong output order. e.g. do the downstream algorithms (in
Bewegungsmelder) assume that the (upstream) blob-labels are ordered
from top-left to bottom-right?

 Maybe ricoardo can tell us more about the changes? If the changes 
 are worth to keep but can't be compatible to the original i see
 two options: 1. make ricardos version pix_multiblob2

anything but this name!
personally i do have the bad habit of using version numbers in object
names ([pix_texture2], [pix_movement2]) but i always regretted it
(even though [pix_texture2] is somehow related to (non) power-of-two
textures (hence the '2'), and [pix_movement2] is something like a 2nd
order [pix_movement]).

 2. send a message (and second argument) to pix_multiblob to set it 
 to the alternative (ricardos) mode.

hmm.. i always wanted to add a 2nd argument / mode-message to change
the output format from the current iemmatrix mode to a more pd-ish
format (a number of lists).
i'm a bit afraid of having too many options for anybody to be able to
handle.

but yes, basically these are the two ways how to proceed if the two
algorithms cannot be made compatible. (and i only wrote down my
concerns so we can circumvent them)

generally, i find it always pleasing, if an error is not (only)
printed to the pd-console but you get some message back into the
patch, so you can react on the error programmatically.

 I'm wondering if it could be good to have a dictionary instead of a
 hash table : when we use [set id sizex sizey pixel_format( message,
 pix_share* could try to find the id in the dictionary if there is
 no entry with that id, it generates a random shmem id, verify that
 nobody else is using it and tries to allocated data if it fails it
 could generates another id until it succeed and store the id in the
 dictionary
 
 pix_share_read will know the dictionary and can find the right
 shmem id

how is that supposed to work in two separate instances of Pd?

that's a bit crude, as you might need a given library for other
reasons than Gem, so uninstalling might often not be an option.

the canonical way to deal with it, is to disable support when running
configure:
./configure --without-mpeg

 Post the build transcript if you want to try to fix it.


definitely.
even if you have found a way to make it work for now, i would still be

on debian, Pd and Gem install their headers into /usr/include/pd resp.

 The only extension is .m3u what VLC handles for me anyway, but
 neither opening it in PD with the extension nor without works.

actually i don't think it is really possible. (even libvlc has removed
direct support for playlist-files; the application has to parse the
playlist and then create a media_list_t structure according to it,
which can be played; Gem does nothing of that kind)

otoh, m3u is a rather simple file-format; you could even try to parse
it from within Pd.

 And still the question is how do you loop it pd? send a [loop(
 message to pix_video or in the message box there should be a loop
 command?

that's a tricky question: how do you loop a live-video stream?
after all [pix_video] is really an interface to infinite pix streams,
not to fixed-length media; hence you don't get information about film
length and EOS, which you need if you want to loop.
the object to play fixed-length media is [pix_film].
unfortunately, there is no VLC backend for [pix_film] so far.
luckily there is a GMERLIN-backend for pix_film, which can play a lot
of files as well.

[GEM-dev] upgrading Gem's sourceforge project

2013-01-17 Thread IOhannes m zmoelnig
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

hi all,

i'm currently thinking of upgrading the pd-gem project on
sourceforge, since sf seems to want drop support for the older system
on the long run (and i'd prefer to do it while i can choose when to do
it).

some information on the upgrade process can be found at [1].
i think the main difference we will experience is, that the repository
address will change.
OLD: ssh://pd-gem.git.sourceforge.net/gitroot/pd-gem/Gem
NEW: ssh://git.code.sf.net/p/pd-gem/Gem
(or git:// rather than ssh:// for anonymous checkouts)

from other projects i have migrated it seems that the old repository
will stay available, but they won't get automatically synched after
the migration (which might to lead to some confusion until everybody
uses the new URL)(btw, it seems to be possible to manually push to the
old repository for now)

if somebody has objections, they should speak up,

 i've already tried to make a C++ external from the template but i

pix-opencv depends on external libraries, and afaik often needs
specific versions thereof.
i think it is a perfect candidate to *not* use a template Makefile but
instead use something more intelligent like autotools, scons,
cmake,...which reminds me that it already does use autoconf

 
 and what about including it in Gem ? as it depends on it (and it
 may depends on very new feature such as ROI soon) i think it's a
 better choice

pix-opencv is developed by different people than Gem. i think it is
good to keep the repositories (and user-management) separate.
so: i'd rather not have pix-opencv be part of Gem.

but:

i agree that pix-opencv could be made more readily available to users.
it might be a good idea to distribute it together with Gem-releases.

so:

the build-system needs little changes to build a pix_opencv found in
extra/ (basically, uncomment the relevant lines at the end of
extra/configure.ac and add a line to extra/Makefile.am)



we could then create a script that pulls in pix-opencv to
extra/pix_opencv before the builds are actually started.

caveat:
both Gem and pix-opencv are complex projects. Gem has slow release
cycles, those of pix-opencv seems to be even more so.
synchronizing both projects so that we can create a stable
Gem-package including a stable pix-opencv could be impossible.

so in a way it would be better if pix-opencv was distributed
separately, but actively.

 i think this is a good idea i usually make changes to pix_object to
 fit the requirement of my working projects if i have the
 opportunity to do that for other objects (and i hope this happens
 soon) i'll let you know


so my plan is actually something like this:
- - add a new property ROI to the GemState.
- - add a new object [pix_roi] that allows you to set the roi in a
normalized form (0..1 rather than 0..width); this object will simply
set the ROI property.
- - have the pix_objects use these roi-property.

in order for the latter to work more consistently, it would be nice
(in a 2nd step?), to change the architecture of the pix_objects slightly:

- - add new virtual methods called like
  processLineRGBA(void*data, unsigned int width, imageStruct*img);

for line-wise processing (with context).

GemPixObject would then take care of calling processLine correctly for
the given ROI.


if done correctly, we could also utilize this to allow parallel
processing of pixes as well (see [1].

 the help patch have been updated and i also make an example
 04.pix/27.bitmap_font.pd
 
 feedback are welcome feel free to include it in Gem
 
 
 thanks for your patches.
 
 eventually i would like to have generic ROI support for all pix_

 this however, would require a rewrite (substantial adaption) of
 the processing core of all objects :-(

i started to implement [pix_roi] and adapted [pix_set] accordingly.

[pix_set] now also tries to write on an incoming image (rather than
always using it's own image). hopefully this won't break anything.


check whether it does what it should.

 Summary: gem 0.93 does not play .mpg files on Mac OS X

as chris has pointed out, it's probably better to drop mpg support on
OSX, rather than trying to fix it (esp. since i don't have too much
time right now).

it _is_ a regression, but with a low priority.

 I think we should leave it open for someone to fix rather than 
 removing it, but I agree, it is low priority.
 
 
 I suggested removing the alea.mpg file (and maybe replace the other
 antiquated media files too).
 
 There is no way to remove MPEG-1 support as it's part of 
 Quicktime.

ah yes, with dropping mpg support i mainly meant not bothering
about how good or bad mpg files play back (thus, officialy not
supporting it) rather than removing code that deals with mpg files.

check for errors on the Pd-console (and probably on the cmdline as well).
maybe your longer videos are simply using a an unsupported codec.

ah.
looking at your patch i see that you only added the keys to the

so you already could have changed the values, but the interface did

so i did include the object, with a noteable modification:
color ranges in Gem are always normalized!
e.g. it should be 1 1 1 1 rather than 255 255 255 255.

this change will break your (riccardo's) patch, so take care!

PS: [pix_equal] could have been done with [pix_curve] and is virtually
identical to [pix_alpha]

most likely the missing tests have been build correctly, but they are

e.g. the debian package does not install any of those test binaries.

i attached a minimal example that should trigger the same problem
(according to your backtrace).

if the example crashes, then i think it is a problem with
gmerlin-avdecoder itself (or i forgot to initialize something, but
burkhard should know an answer to that as well)
if it does not crash then the problem is with Gem (btw, when creating
the test, i noticed a small typo in Gem's filmGMERLIN which might simply
fix the problem...so if the test runs ok, try an update of filmGMERLIN...)

 Hi,
 
 Bug 3222807 should be reopened. Or if you prefer to file a new one and
 copy-paste the information because it is good for the bugs-closed
 statistic then go ahead.

while i do like bugs being closed (also for the statistics :-)), this is
usually not the reason why a ticket get's closed.

also:
if you talk about a specific issue, please provide a link.
it is not very hard to go to the sourceforge page, navigate to the
tracker (hopefully choosing the right one), pasting the bug-id you gave
into the search field, doing a search and then clicking on the result.
however, it is super-easy to just click on a direct link to the ticket
(and i figure it is about the same amount of work for you to copy the
correct bug-id as to copy the entire url)

furthermore:
if you want to re-open an automatically closed bug, you should be able
by adding another comment to the issue. sf will automatically re-open it.

and:
keep in mind, that if a given bugreport closed as fixed, this doesn't
mean that a specific version of Gem will suddenly stop having a given
problem. bugs are usually closed as soon as there is a fix in the
current development branch of Gem. this doesn't mean that you as an
end-user can already download a fixed release.

 
 It affects both Windows and Linux. Zmoelnig said he tested it on Mac OS
 and works, I believe that, but I've tested it again on Linux and I
 confirm the issue. And windows of course.

the ticket has been closed because it is really believed to be fixed.
only now i tested with a git-snapshot of Gem (b41709baf), and
Gem-0.93.3, as is packaged in Debian.
both can load the sol2.tif file just fine.
and yes, i have installed the imageMAGICK plugin for Gem
(gem-plugin-magick on debian) to do the decoding.
imageMAGICK is _the_ plugin to load images on linux. if you need to be
able to load a large number of different image-formats, then you really
should use it.

if you are on w32 or OSX, starting with 0.93 you can use the imageQT
plugin on both platforms, which uses QuickTime and should be able to
open any image file that QuickTime can open (if not, it's a bug, and it
is definitely a separate bug from #3222807; if you think that this bug
is (still) there, please go ahead and open a new bugreport).

note that i cannot currently test whether it works as expected on w32.

obviously, you will need QuickTime installed on your machine, in order
to use imageQT (OSX (i386/ppc) already comes with it; in w32 land, you
have to install it manually).
i don't know by heart, whether the Gem-0.93.3 w32-installer has the
imageQT plugin selected by default; however, it is definitely included
in the installer.

 Also note the annoying threaded loaded image: ... as if the image was
 succesfully loaded (well it is succesfully loaded but not decoded).

well, if you get the dreaded threaded loaded message, you are surely
using an uptodate version of Gem...

 
 - regarding windows, Zmoelnig said:
 w32: Gem uses some rather old static code to decode image files (hence

 not be able to read your TIFF file, and i have no real intent to fix this;
 rather, the w32 version should switch to a more common API (DirectSomething

 Well that definitely needs to be done.

no.

 that's true, but i'm not sure it's a widely used feature, my sense is
 that people will create multiple gemvertexbuffer instead.

which could mean that the documentation is lacking.

 

 i don't really see a strong interest splinting gemvertexbuffer in 2 
 different objects, but if you do so, and if you are ready to code it, then i 
 have no objection, as long as you can provide a compatible abstraction that 
 replace the current gemvertexbuffer object.
 
 of course, i wouldn't want to break your current functionality.
 

no problems from my side.
i don't especially like the _name_ [gemvertexbuffer] (it is too similar
to [gemframebuffer] (which goes well with [gemwin]), but the
functionality/usage is very different), and if it was made into an
abstraction, all the better.

one could also use something like [pix_texture], that applies textures
that it either generated itself (from a pix) or that was generated
somehow else (by taking the texture id in it's 2nd inlet).
but i'm not so sure that this scales well for the different VBO types.

it seems, that you somehow managed to have the Pd sources at the same

something like:

i think a simpler approach is taken using the new [gemvertexbuffer]

shouldn't that be enough for your needs?
most Geos could be implemented as an abstraction based on

well, you the Gem binary release has been compiled on machines that have
more development libraries installed that your machine; therefore there
is support for some more backends, which results in more plugins (files
with .so extension)

anyhow, you should even be able to use the plugins from the release with
your self-compiled Gem!

 and I also miss the
 Gem.pd_Darwin

well, you specified that you wanted to create a Gem.d_fat, rather than a
Gem.pd_darwin at the cmdline.
you get what you ask for.


 I thought I could just take Gem.d_fat and the so files and place it in
 /Library/Pd/Gem
 which I did, PD-extended starts but shows compiled Nov 10 2011

this seems to be a bug in Pd-extended, which (for reasons of
incompatibility) prefers to not be able to load .d_fat files on osx and
instead uses only .pd_darwin (though - for reasons unknown - it allows
e.g. .l_i386 and .pd_linux on linux/i386; so this seems to solve some
special osx issue)

i would advise you to file a bug-report against pd-extended.

 
 Everything seems to work, but I figured it uses the Gem.pd_Darwin
 universal binary.
 
 So I tried this configuer line:
 
 ./configure --with-pd=/Users/maki/Development/pure-data/src
 --enable-fat-binary=i386
 
 the output from configure tells me that the target is now Gem.pd_darwin

right; you could have simply renamed all .d_fat files to .pd_darwin

 
 After make, when I copy the Gem.pd_Darwin into /Library/Pd/Gem
 PD can't load it and says Symbol not found : _sys_close expected in flat
 namespace

again, seems to be a problem with Pd version mismatch.
i suspect that you compiled Gem using Pd-0.43 and are now using Pd-0.42
(or some other older version).
it's always best to use the same version for compilation and running!


 
 I also have some class files that I've added to the sources but the
 seem not to get compiled. (That's the reason why I need to compile Gem)
 I can't find the corresponding object files.


depends on how you added them.
just putting the .cpp/.h files into src/Pixes/ is no longer enough!
you have to explicitely add them to src/Pixes/Makefile.am

i haven't found a useable one yet.
in theory, there are android-for-eee images availabe, which should , and
there is myOS[1], which i haven't tried for some time (though it seems
to be a dead project anyhow) but it never worked with my nvidia-card...

if you have success in getting a simple setup for GL-ES development,
please let us know!

 i'll keep everyone up to speed as i make developments, and if anyone can

regarding FTGL:
$ configure should find automatically, that you don't have FTGL
installed and disable it for you.

finally:
your subject mentions Gem-0.93.3 and OSX-10.6 in one line.
the _only_ way to make this work is by forcing the build to be i386 only.
look at the configure flags (./configure --help), there should be (oh,
0.92 is a _long_ time ago) a flag that allows you to set the
architecture/fatness of the built dll.
something like: --enable-fat-binary=i386 should do the trick.
if it does not, you might have to add -arch i386 to the CXXFLAGS and
LDFLAGS manually (and make sure that there are no -arch x86_64 anywhere.

no. GetMimeList() is a member of the imageMAGICK class. it seems like
your imageMAGICK.h and imageMAGICK.cpp are slightly out of sync - e.g.
because you modified one or only updated the other.
alternatively it could mean, that the build-system is somewhat broken so
that the 2 files are _made_ out of sync (with some compiler switches) -
which should obviously never happen.

2012-01-05 Thread IOhannes m zmoelnig
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

i just pushed a changeset to sourceforge, that adds some possibilities
to 3d model loading to Gem.

first, model-loading is now factored out into plugins as well. the old
.obj loader code has been ported into a new gem_modelOBJ plugin.

then i tried to create another asset importer plugin based on assimp.
the plugin is (not surprisingly) called gem_modelASSIMP.

assimp [1] should allow us to read a large number of 3d model formats
(including dfx, 3ds, md5, blender, collada,...)


what works:
- - loading of models
- - UV-textures

what needs to be done:
- - check for other texcoord generations.
- - allow feedback on which textures should be loaded
- - probably do the texture loading within the model-importer (on
user-request)
- - implement animations
- - improve performance

cudos to hans for bringing assimp to my attention.

check and have fun (and report back any problems...)

 hello,
 
 I commit few change in the vertexbuffer branch.
 it look like it's ready to be merged with the master.
 
 Iohannes, could you check and merge it if you agree?

i reviewed the code, and tried to do it nicer :-)

changes so far:
- - proper initialization of all class members
- - created class that contains all the data for a single VBO; which can
then be reused for position/color/...
- - single messages to set all data of a VBO in one go; e.g. position
tabX tabY tabZ rather than posX tabX, posY tabY, posZ tabZ
- - allow interleaved data, e.g. position tabXYZ

- - i really dislike the name posVBO_enable: where the hell does VBO
come from? changed it to position_enable (et simil.)

- - updated the help-patch

please check whether it still performs as intended.

if it's ok, i'll include it.

Gem now has a videoVLC plugin, that allows to open any medium playable
by VLC to be opened as a video-device, by specifying the vlc-URI as the
device

e.g. using [device screen://( will grab the screen and make that
available as video stream.

i had a look and found the following:
- - the code was always buggy :-)
- - it used fixed color offsets within pixels (e.g. 3 for blue), which
is simply wrong on OSX. Gem has special constants chRed,... for
platform independent color offsets.
- - i also changed the color-type from GL_RGBA to GL_RGBA_GEM, which will
actually do the same (GL_RGBA on w32linux and GEM_BGRA_EXT on osx) but

[GEM-dev] Gem MinGW

2011-12-14 Thread IOhannes m zmoelnig
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

as you might have noticed there have been some bug tickets regarding
MinGW in the last days.
you might also have noticed that all of them have been set to pending/fixed.

this basically indicates, that it is now possible to compile Gem on MinGW.

what is working:
- - Gem *core* compiles
- - Gem loads
- - this means that all objects are available
- - the plugin mechanism works

what is not working:
- - you'll not be able to load a plugin compiled with VisualC++ into a
MinGW-compiled Gem or vice versa
 (at least as long as there is no C-API for plugins)

- - what will need some more work
DirectShow image acquisition (videoDS, filmDS) will need to be
reimplemented for MinGW...hopefully in a way that allows the new
implementations to be used with the M$VC builds as well...

what is unknown/untested:
- - i haven't had any libraries additional libraries installed
 thus i don't know, how much work the following still needs: FTGL-,
QuickTime-, JPEG-, TIFF-, ImageMagick-,... support
 (actually, the only plugins i was able to test were imageSGI (for which
i lacked a test image to load) and videoVFW (which does not support my
camera)
chances are high, that most of these libraries will just work.

 the name of the branch is:

 I've cloned the Gem sourceforge repository, then i've created a branch,
 worked on the files, and then i've pushed my modifs on my github

 Is this the good workflow for contributing to Gem using git? or do you
 prefer another way?

yes, i think this is the best way to contribute to Gem.
i incorporated your fixes and pushed to sourceforge.

i'm not yet sure whether it is best to _merge_ your branch into master
or to _rebase_ it onto master.
for know i prefer a rebase (if possible), but if that makes problems for
somebody i could do merges as well.

if you agree and are willing to change the name in your branch, i'll
import it as is.

 'white' (and a seventh 'not sure' class label). However, to me the output
 is in symbolic form. The 'red' symbol is encoded  as [1 0 0]  and so on.

makes sense.
some more remarks (without having looked at the code in detail, so i
might be asking for things already there)
- - it would be great if the user could modify those labels. e.g. [1 0 0]
sounds like a great label for red, but some weird user might chose to
prefer [0.5 1 0.8].

it would also be nice to be able to parameterize the detection code, but
i guess it is too fine tuned to the six given classes (so it would both
complicate things from the dev's and the user's povs)

i think the problem is the CPU capabilities detection code (which tries
to determine whether your CPU is capable of running e.g. SSE2 code)

given that any x86_64 CPU on the market supports SSE2 (and SSE and MMX),
i disabled that check on this architecture for now.

at least, this fixed the problem here.

 so, latest git did not compile.
 i add 2 ; in order to compile.

doh!
i had only MMX enabled when compiling, so i didn't catch it...
should be fixed now.

 
 but this did not really solve my problem.

hmm...

in this case i need more info about your system (architecture, configure
flags, compiler flags,...)

 about bugs to be fixed comment in this patch :
 1 - should be fixed since yesterday thanks to Iohannes
 2 - i don't think i have this problem on my computer. (i add a translate
 on the scene B in order to have the square cut by the edge of the
 windows, and the blur did not appear  on the other side of the window.)
 see : http://chnry.free.fr/blur.png
 did i miss the problem, or did it work better on my computer than on
 your's?

as said, i couldn't see it either.
then i played around a bit, and manged to produce this [1].
@guido: is that what you mean?

 The GNU/Linux issue is fixed, with the __sync_bla_bla symbol.


 when? by whom? how?

 you reported that bug, no changes happened on the Gem side, and 3 days
 lated, magically, the issue is fixed?

 sorry that i got confused...
 
 
 I caused the problem by adding CPU/optimization flags to Gem's CXXFLAGS
 in externals/Makefile.  I posted on some thread about it, I thought it
 was this one.  To fix it, I just removed that change.
 
 http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/externals/Makefile?r1=15612r2=15619
 

ah, thanks for the clarification.

after re-reading the thread i notice that you mentioned that you
removed that, but haven't tested it again yet.

this was eventually overlooked by me, as it was in the same email with
the 2 (then 3) questions for definitive answers.

 Hey IOhannes,
 
 I would like to include the latest version of Gem in Pd-extended 0.43. 
 It currently needs a little work.  It builds on GNU/linux, but gives a
 missing symbol (something like _sync_foo_bar).  

it builds on GNU/linux without the missing symbols as well, else i
coulldn't use it myself :-)
i assume that this is on some ubuntu flavour (which one), with a certain
compiler version (which one) and some special C(XX)FLAGS.

according to the internet, adding something like -march=i486 to the
C(XX)FLAGS should help.


 It doesn't build on Mac
 OS X 10.5.

what does latest Gem mean here?
the git version (which is indeed the 'latest') of Gem has the issue fixed.
the 'svn' version (both trunk and branch/0.93) and the releases have it
not fixed (yet).

if you want/must stick to the current release (which is fair enough) or
svn, a very simple workaround would be to add /sw/bin to the beginning
of the PATH before calling Gem's autogen.sh

using -j4 is nice to speed up things, but it makes finding errors harder.
in order to get reasonable information at a reasonable speed, run a
non-parallelized make right after the failed build with -j4.

something like
$ make -j4
$ make

then you should be able to give us information where it actually failed.

 
 the same error with make install. i have to add -I
 /usr/include/ImageMagick to find image magick headers
 shouldnt make install just copy compiled stuff to prefix directory?

it will do so, if the build has succeeded.
if the build is not complete yet, it will first try to finish it.
since your build stopped with an error, it did not complete yet.

yes, that file has been deleted :-)
the documentation was unfortunately not updated before the 0.93.0 release.


speaking of which: why are you using 0.93.0?
there is a 0.93.1 release available. micro release numbers indicate
bugfixes...
