Hi Eduard, unfortunately I don't have any tips for the error you're 
getting. A couple months ago I tried getting OSG to use the DOM trunk 
code for its Collada support, and other than a few easily fixable 
compiler errors it worked fine. I didn't get any .so load errors. I was 
testing with Ubuntu.

I plan on submitting a patch to bring OSG up to using DOM 2.0. That 
should be sometime this month.

Re: [osg-users] osg-conv collada

[Eduard Trulls]

Hi,

I'm trying to get the collada plugin working and running into this 
problem too. I've tried Johan Nouvel's suggestion (a few messages later) 
to no avail. I'm using osg 2.3.7 and the last pre-2.0 stable release for 
collada, 1.4.1 DOM 3.0. Did anyone find a way around it?

Also, what are the plans for the plugin now that 2.0's out?

Thanks,
Eduard

Re: [osg-users] osg-conv collada

[Johan Nouvel]

Hello all,

I have the same problem with OSG 2.2.0 or 2.3.6, collada plugin and collada 1.4 
dom 1.3.
I've search on collada forum and found 2 things :

1- in the collada_dom source, dae directory, edit the Makefile_PC to add 
daeRawResolver.cpp and compile as usual.
COLLADA_DOM/src/dae/Makefile_PC:
[...]
# files
SRC  := dae.cpp \
 daeArray.cpp \
 daeAtomicType.cpp \
 daeDocument.cpp \
 daeDom.cpp \
 daeElement.cpp \
 daeError.cpp \
 daeErrorHandler.cpp \
 daeIDRef.cpp \
 daeMemorySystem.cpp \
 daeMetaAny.cpp \
 daeMetaAttribute.cpp \
 daeMetaChoice.cpp \
 daeMetaCMPolicy.cpp \
 daeMetaElement.cpp \
 daeMetaElementAttribute.cpp \
 daeMetaGroup.cpp \
 daeMetaSequence.cpp \
==> file to add daeRawResolver.cpp \
 daeSIDResolver.cpp \
 daeStringRef.cpp \
 daeStringTable.cpp \
 daeURI.cpp \
 domAny.cpp

[...]


2- in OpenSceneGraph-build-tree/src/osgPlugins/dae/CMakeFiles/osgdb_dae.dir 
directory you have a file named
"link.txt". This file contains the link command to produce osgdb_dae.so from 
all object file. For some reasons all the 
collada the collada libraries are not here. So I modified this file and run it 
to produce a new osgdb_dae.so which works 
fine (no more undefined symbol).

old build-U7.04_32/src/osgPlugins/dae/CMakeFiles/osgdb_dae.dir/link.txt:
/usr/bin/c++  -fPIC   -O3 -DNDEBUG  -shared -Wl,-soname,osgdb_dae.so -o

new command to build osgdb_dae.so:

osgdb_dae.so *.o -LSOMEPATH -lOpenThreads -losg

-lm -lOpenThreads -lpthread -lGLU -lGL 
-lSM -lICE -lX11 -lXext -Wl,-rpath,SOMEPATH
note that -lcollada_dae is include twice as specified in collada forum.

I'm sure it is possible to modify CMAKE to do the right things, but I'm not 
CMAKE fluent and it is scheduled that all 
this will die with collada DOM 2.0 and OSG 2.4.

Hope this will work for you,
Johan.

Re: [osg-users] osg-conv collada

[skunkwerk]

I've tried running the prebuilt binary for osgconv on Linux, but they don't
come with osgdb_dae.dll - could someone please send me a copy, as I don't
have visual studio?  or could someone send me their osgconv_dae.so on linux
to try on my system?

i'll try recompiling everything again...

Re: [osg-users] osg-conv collada

[skunkwerk]

thanks Jean,
   i don't seem to have anything defined my LD_LIBRARY_PATH - should I?
After I set it to:
/usr/local/lib:/home/me/Programs/OpenSceneGraph/lib

I'm still getting the same error... I installed lib-xml through ubuntu's
apt-get system, so don't see how I could have compiled the collada-dom with
something else.

any other way to figure out what's causing this?  isn't there any pre-built
package for openscenegraph with the collada plugin?

thanks

Hello,

> how can I fix this?

Is your collada dynamic library and its dependencies on your 
LD_LIBRARY_PATH? In particular, it looks like it's not finding a symbol 
from libxml. Is that on your LD_LIBRARY_PATH?

Alternatively, was your collada linked with the same libxml (and other 
dependencies) as you have installed on your system? If it wasn't, try 
rebuilding the collada libs. Sometimes linking with a different version 
of a library can mangle names differently and you'll get an error like 
you're getting.

Good luck,

J-S

You might need to set your OSGNOTIFY environment variable to DEBUG and

You need to run ccmake . again, so CMake can search for the DOM and find 
it (if you installed it in /usr/local, it should find it 
automatically).  Once that's working, you can reconfigure and regenerate 
from the ccmake interface and then do make clean; make; make install.

If this doesn't work, you've gone beyond the scope of my knowledge and 
might need to seek help elsewhere :-)

I assume you're on Windows.

 From this page on the wiki:

http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/VisualStudio

you'll see a link "Help for compiling specific optional plugins" which 
leads you to this page:

http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/VisualStudio/VisualStudioPlugins

Which has info for compiling a few plugins with Visual Studio, including 
the COLLADA plugin.

If you installed the COLLADA DOM, you should just need to make sure 
CMake can find it (run ccmake . again and specify the path, if 
necessary) and then re-make OSG.
