Clang is consistently faster at compiling than GCC and it is very clean and 
modular -- not bloated.

clang is slightly slower (nearly comparable) to gcc, produced similar 
sized code, that executes in similar speed (0.5% difference in CPU time),

while clang itself is 5 times bigger.

sometimes spending just a few minutes to CHECK how things are is far
better than following a hype. I would say not just sometimes, but always.


Don't forget that gcc is result of much over 20 years of constant 
patching, modifying, adding and changing the same code which MUST result in bloat 
and inefficiency.


Clang written recently with fresh look resulted in no faster, but far 
more bloated program. quite strange IMHO, think what will be within 5 
years.

libc version

2012-06-18 Thread Sergio de Almeida Lenzi

Hello...

I upgrade the server from version 8.2 to 8.3, and rebuild all packages..
it all works...

Then I installed a binary package (8.3) in an old 8.2 ...
every package works... gnome, nautilus, wget about 800 of them
the only one that does not work is postgesql84-server
when I try to run it it I got the message:
/libexec/ld-elf.so.1: /lib/libc.so.7: version FBSD_1.3 required
by /usr/local/bin/postgres not found

seems that only postgres is check for the libc version???
is there a compile switch to check for that???


Of course, if I compile postgres in the 8.2 or upgrade to 8.3 it
works...

Thanks for any help,

 These pertinent messages come when the announcement of a new Wine-fbsd64 is
 announced.

I am the one who sends these persistent messages.  Some users of my packages 
reported that wine didn't run due to a clang compiled world.  I never verified 
them (although I got multiple reports).  With the updates to clang it may have 
also been corrected.  

I attributed the problem to clang miscompiling a library in base used by wine 
and Volodymyr, I think, confirms this:

 For me I'm just waiting on toolchain stabilization as both this one and
 (open|libre)office fail because of libgcc_s compiled with clang on amd64.

(Free 7.2) su -l didnt prompt password.Is it possbile?


Hello everyone.
We'v noticed some strange situation. After reboot and login, system 
didn't ask for password while switchig with su -l.


In details, there was root login from terminal and one from ssh.
Terminal login was directly as root(via ip-console), and ssh was as 
user, then attemped switch to root with su -l, and there were NO 
password request,no prompt at all. At the same time login from terminal 
accepted root password, first I thought that means password wasn't 
empty, but system even with empty password should print Password:..and 
that time it was nothing absolultey. We even logged out and then su -l 
again.


And It looked such way:

%su -l
St-serv#
St-serv# exit
%su -l
St-serv#

We'v been shocked and hurried a bit and changed root password without 
/etc/master.passwd backup for explorations.

After chagning password we cant no reprocude such behaviour.

It's also should be noticed that system was booting after unsafe power 
shutdown, and there was fs-check running in background(accroding to 
logs), corrected cleared some files(searching by inum resulted to nothing).


sysctl -a gave such string:
118Starting background file system checks in 60 seconds.
118

and in /var/log/messages we could see:

I'v googled and found only one thread with su didnt'asking for password, 
that one was abut jails, but this time we have a 100% garanty that we 
didnt put any virtual enviroments.


So the thing that scares is, mb this is symptop of server rootkit? (We'v 
found nothing unusual in logs but it means nothing...) Or there is some 
other explanation why su could not ask password?



Thanks in advance

Unfortunately, we can not flashback or reproduce that step now, cause 
we'v hurried and changed root password to avoid such strange free 
logins. And changing it back didnt change a thing. It was...and't went. 
We had only buffered console output :(
But mb you can point in what case there is possibility to make su -l 
without any prompt. I suppose you mean that user has gid=0 or smthng 
like that but it hasn't. And as i mentioned changin root password to 
another and backwards doesn't allow to reproduce discribed behaviour.

Empty password behaviour is for no prompt, so what you are seeing is
normal, and means that you did indeed have a empty password.

Check your logs very carefully over the past few weeks to make sure no one
has broken in.

Interesintg could it be that master.passwd file corrupted (after power 
shutdown) and fsck corrected in background.. which resulted in such 
behaviour.


The strange thing with possibly empty password is that login from 
ip-console accepted correct password. So dont sure about empty...It 
seems like su was accepting any password at that time.


Check your logs very carefully over the past few weeks to make sure no

Yeah, seems we are forced to mount disks to another system and check for 
changes in critical system tools. Arghand then anyway redeploy system.

The only thing I can think of ATM is .. did you recently perform and
upgrade from source with this system ? mergemaster ?

The reason why I ask is that when doing such things the master.passwd is
compared to the default master.passwd which has no passowrd set. If a
merge when wrong then there is a possibility that it was set back to
defaults by accident.

I also see that your system booted up and did a fsck(8). There is a
chance that something wierd happened here as well.

Fwd: Error in latest KDE4 install attempt

2012-06-18 Thread Lynn Steven Killingsworth


Hi FreeBSD -

I thought someone would probably inspect the files for KDE4 so I would try  
to install periodically.  This morning the error messages were slightly  
different.


While attempting to install qzeitgeist-0.8.0 my machine almost immediately  
states that moc 4.8.2 has changed too much for these to be compatible.   
[During verifying qt-something]  Then there is a list of items that are  
'not in scope' - for instance monitoradaptor or  
classOrgGnomeZeitgeistDataSourceRegistryInterface.


A fetch command for qzeitgeist-0.8.0 is not given so I would not know how  
to fetch a newer version if I knew the newer version.  Which is to say are  
all the fetch commands from the distfiles directory?

Date: Fri, 15 Jun 2012 07:36:20 -0400

Hi FreeBSD -

I have just updated my Ports again this morning and I still have the same
problem installing KDE4.

When verifying libphonon.so in /multimedia/phonon [phonon-4.6.0-1][from
the numbers it appears to be KDE4 4.8.4] my machine does not find library
qzeitgeist.1 so it begins verifying the install of qzeitgeist-0.8.0 .  The
installer then determines that this version of qzeitgeist is not
compatible.

Since the master site seems to be unavailable much of the time how can I
determine the tar.gz from the version number so that I may have an for
instance //ftp1.freebsd.org/ to put in the the master site change in
the make fetch command?

Thanks - Steve

Are your ports up to date? Also, did you apply any funky compile time flags?

yes and no.

Yup, so Ports symlinks (without full path -- this should be fixed) and  
FreeBSD BASE uses a hardlink.

I really don't care about cool graphs but at facts for me as a USER (not 
developer) of C compiler.


And the facts are: Lots of worktime were spent to make new C compiler from 
scratch and this resulted with thing 5 times larger, working at similar 
speed and producing similar code to GCC that is already considered bloat.


Not something to be proud about.

That's truth. and truth is the only thing i do care about. I leave hype 
and propaganda and cool graphic bars that shows a really not important
part of C compiler performance - code parsing and generating unoptimized 
code (-O0).


The truth is sad. Starting from fresh and not being able to beat 25-year 
old bloated gcc is just funny.



That's my view - as a final consumer, not developer. My view is that 
bloatware is replaced by another bloatware, which - because of it's young 
age - have greater future potential of bloat than GCC.



This tens or hundreds of thousands of work-hours could be spent far better 
by getting latest gcc available on GPLv2 licence and start from there, 
just improving it.


GNU communist licence for C compiler is not bad at all (contrary to other 
software).

We already have the latest available with GPLv2, which is very far behind  
and it requires GCC codebase experts to make any changes at all. This is  
equivalent to letting any random coder make major changes to OpenSSL --  
you simply cannot afford to risk it.


Yes, I noticed you showed a few benchmarks where Clang was slower. It's  
bound to be a bit slower with some test cases at first -- they're rounding  
out the features before going back for major optimizations. It won't be  
long and it will be sufficiently on par if not exceeding GCC's  
capabilities. Writing a compiler is no trivial task, and they've built the  
right framework and have a very active community.


Listen, Apple has a MAJOR investment in Clang/LLVM. They simply would not  
allow major across-the-board speed regressions to happen during the  
release of iOS or OSX. They're going to throw tons of time and money to  
make it destroy GCC and target any ARCH they have the slightest interest  
in. Clang has a very bright future, so don't be so discouraged.

Anyway far behind gcc is roughly as good as leading edge clang.

Actually - lots of time spend and zero gain.

If you want to recompile everything with lang/gcc (4.6.3) and the latest

Clang is a great set of compiler tools. If you are only a user, as you suggest,
than you shouldn't be compiling anything, just running binaries. If you are
using a compiler, than you may not be a developer, but you aren't just a user.

In any case, if you're not developing, like me, you don't really get a

you do, but probably nobody is listening.

 Subject: libc version

 Hello...

 I upgrade the server from version 8.2 to 8.3, and rebuild all packages..
 it all works...

 Then I installed a binary package (8.3) in an old 8.2 ...
 every package works... gnome, nautilus, wget about 800 of them
 the only one that does not work is postgesql84-server
 when I try to run it it I got the message:
 /libexec/ld-elf.so.1: /lib/libc.so.7: version FBSD_1.3 required
 by /usr/local/bin/postgres not found

 seems that only postgres is check for the libc version???

INCORRECT.  Postgres is jjust the only one of those programs that
_requires_ a 'minimum' version level that is newer than the one
installed.

 is there a compile switch to check for that???

No.

 Of course, if I compile postgres in the 8.2 or upgrade to 8.3 it
 works...

Naturally. do it right and it will work'.  grin

The required _minimum_ version of a runtime library is specified in the 
program source code -- because it uses features that did not exist in
any version prior to that one.

There is *NO* way to tell _at_compile_time_ what version of a runtome
library will be present when the program is executed.

The 'compiled on 8.3' Postgres binary requires a newer version of libc
than exists in 8.2.   Compile on 8.2 and it builds using diferent code
that does not require the newer libc feature.  hence the 8.2-compiled
code works on 8.2.

The solution to your problem, as you found, is to _not_ use 'more current'
binaries in 'down-rev' environments.  upward compatibility is almost
always present in a package.  backward compatibility is *always* a
crap-shoot.

Ok thank you for your answer...

the problem  is in the postgres code and not
in a compile switch or something like that...

I will upgrade all my 8.2 to 8.3... systems

to do this, I build an 8.3 from ground zero,
and than do a rsync from this one to the others,
directories: /usr/obj /usr/src
than... on each target, a make installworld installkernel should do the
upgrade...

Any comments??

This might be to gratuitous for most on the list, but diversity is almost
reason enough. And I don't mean this is some sort of fashion-way. I
think llvm and clang are interesting and serious projects.

Actually, to be honest, c programming with clang is really
nice, it gives me really nice error messages, which makes debugging
easier. I like it for that too.

From a practical point of view, the only negative thing about using clang
is that some applications which have been written using gcc won't compile
using it, but gcc is also ok.

I'm not that interested in saving a few minutes compile time, or bytes of
memory.


 The Clang decision is far-reaching and gives numerous advantages to the

GPL runs contrary to the nature and intent of the BSD style license.
Free and open software benefits us all.

Getting rid of GPL is a good thing, and well worth any (debatable)

Re: Why Clang



gratification  Seems like you ask for it.



This might be to gratuitous for most on the list, but diversity is almost
reason enough. And I don't mean this is some sort of fashion-way. I
think llvm and clang are interesting and serious projects.


never told otherwise.

i just try to do what is really needed - something like mythbusters 
would help greatly here.


clang is very good C compiler, but JUST NOT BETTER than gcc.
overall it is comparable. at most.

wouldn't it be better to say - well, clang is good and OK, and we are not 
dependent of GNU communist licence v3 which is important.


But instead we here lies about incomparably better compiler. No it is not 
better. it is at the same class, in some respect actually worse.___

That's interesting discussion. 

I hit some cases where clang produced binaries were 
clearly faster than those made with latest gcc. But it's far 
from rule.

Where you have found statements that clang is always 
faster than gcc? 

From my perspective, it's almost as good OR better
than gcc, with potential for further improvement and
nice license, errors etc. Fair enough.

  I don't say clang is just bad, but i prefer real data over hype.

  This is the most memorable and impacting set of graphs that I remember. I 
  haven't followed the data much since.

  http://clang.llvm.org/performance-2008-10-31.html

  Now imagine having to rebuild projects constantly during your dev cycle. 
  The 
  time savings is going to add up quick.

 still not read my mail where i actually compared it in real. or don't 
 want?

 I really don't care about cool graphs but at facts for me as a USER (not 
 developer) of C compiler.

 And the facts are: Lots of worktime were spent to make new C compiler from 
 scratch and this resulted with thing 5 times larger, 

*YOUR* measurement of sizes was faulty.  grin

  working at similar 
 speed and producing similar code to GCC that is already considered bloat.
 The truth is sad. Starting from fresh and not being able to beat 25-year 
 old bloated gcc is just funny.

You _do_ understand that they could not use -any- of the technology
implementations in GCC, that they had to redevelop everything from 
scratch, right?

I'm sure that you _also_ are aware that a larger program size does *NOT*
necessarily mean 'bloat'.  

That 'optimizing for speed', which can, and does, result in code that is 
larger than the unoptimized code, is not 'bloat'. 

That increasing the clarity of explanations in error messages -- which 
takes more words -- is not 'bloat'.   

That additional logic to more precisely identify -what- error occured, and 
provide a 'better' identification/explanation, compared to just 'parse error
near {token}', is not 'bloat'.

That writing code for clarity and *maintainability*, even if it incurs
some 'cost' in increased size, is not 'bloat'.  

That doing things the 'long way', rather than the 'short way', because it 
is necessary for _compete_ compliance with a standard, it not 'bloat'.

The fact that this _totally_new_ implementation runs roughly as fast and
generates similar quality code to a package that has undergone over 
two-and-a-half_decades of tweaking and polishing -- well, it is little
short of miraculous that it is -that- good, _that_ quickly.

Feel free to demonstrate that _you_ can do it better, faster, AND smaller.
*WITHOUT* lifting anything from any existing, copyrigthted, code that is.z

 That's my view - as a final consumer, not developer. My view is that 
 bloatware is replaced by another bloatware, which - because of it's young 
 age - have greater future potential of bloat than GCC.

Obviously, you would then prefer to use a compiler which eliminated the text
of all the information/warning/error messages and replaced all those messages
with just 'Error: {number}' -- or, even shorter, just 'E{number}' -- which
was done in the name of reducing that dreaded 'bloat'.  (The reduction in in
executable size from this approach can be _surprisingly_ large).

Obviously, you would also prefer to use a compiler which 'gave up' and aborted
the entire compile after reporting the first fatal error. This will eliminate
all that dreaded 'bloat' involved with unwinding the parse state, and all 
the other 'overhead' stuff you have to do to be able to sort-of continue
parsing the rest of the source file.

 This tens or hundreds of thousands of work-hours could be spent far better 
 by getting latest gcc available on GPLv2 licence and start from there, 

That *cannot* be done.  There is simply *NO* way to license anything derived
from a GPLv3 product under GPLv2.  The GPL itself expressly forbids it.

Thus, one would have to _start_ with a GPLv2 compiler and *independently*
create all the changes/improvements that have been made since that GPLv2
version was released.  This is a _far_ bigger project than converting to 
the use of a different, but _more_standards_compliant_, compiler.

i did few more test on common unix tools, or my programs and results are 
that by average there are just as fast within 1% range.


by average it is just like gcc both im compiling speed and execution 
speed.



Where you have found statements that clang is always
faster than gcc?


from that mailing list - mostly from mark fedler. He even showed me some 
nice graphs to prove it - graphs showed speed of -O0 compilation.





From my perspective, it's almost as good OR better

actually good licence is for me the only adventage over gcc.

But yes - it is great adventage.

I believe Robert Bonomi (you didn't include attribution for the previous

explained what he thought of your glossing over the various factors that
might contribute to binary size.

I notice you ignored most of it in your response, too.

 Really i don't have problems to read gcc error messages when i
 compile my programs.

I can generally puzzle out what caused various GCC warning and error
messages when trying to compile my own code, given comparison of what's
going on in the messages with what's going on in my code and reasoning
through the connections between different parts of the code.  That sort
of thing is required probably 70% of the time, in my experience.

With Clang, by contrast, I find that's required only about 20% to 30% of
the time.  Otherwise, the warning and error messages tend to get me a lot
closer to the actual point of failure than GCC.

*That* is what all this fuss about 'better error reporting' is about.

converting mpost(ed) files individually to eps

2012-06-18 Thread Antonio Olivares

Dear folks,

I am taking a plunge to learning a little bit of metapost.  I have
found examples page using google.

http://www.tlhiv.org/MetaPost/examples/examples.html

I want to convert output files individually to eps.

I can only convert the first one output say file.1 to file.eps, but
when there are more files, ie, file.2, ..., file.10, all the files
between .2 and .10 do not get converted/saved to *.eps extension.

script called mpost-eps below:

===
$ cat mpost-eps
#!/bin/sh

MPOST=/usr/local/bin/kertex/mpost
GS=/usr/local/bin/gs

ERROR=Too few arguments : no file name specified
[ $# -eq 0 ]  echo $ERROR  exit # no args? ... print error and exit

# check that the file exists
if [ -f $1.mp ]
then
# if it exists then metapost it,then convert with ghostscript, then
remove all the unneeded files
$MPOST $1.mp
$GS -dNOPAUSE -dBATCH -sDEVICE=epswrite -sOutputFile=$1.eps $1.1

# these lines can be appended to delete other files, such as *.out
if [ -f $1.log ]
then
rm *.log
fi
else
# otherwise give this output line with a list of available metapost files
echo the file doesnt exist butthead! Choose one of these:
ls *.mp
fi
===

I run the script
$ ./mpost-eps file
without *.mp extension.  but only one gets converted.  I don't know
enough shell programming to do something like
for i in file.i do
$GS -dNOPAUSE -dBATCH -sDEVICE=epswrite -sOutputFile=$1.eps $1.i

but it does not work correctly.  I can change the mpost
executable[using kertex by T. Laronde
(http://www.kergis.com/en/kertex.html) ] at will as I also have
texlive installed by FreeBSD TeXLive Ports by Roman
Tartiere(https://code.google.com/p/freebsd-texlive/) ,
/usr/local/bin/mpost is the executable there, or same one but in
metapost executable by default teTeX.

Is there a magical incantanation I can use to output all the files to
eps and include them in documents either \TeX{}ed or \LaTeX{}ed?

Thanks in Advance,


Antonio

Correct.  The script you showd processes a _single_ argument only.
Use a 'for loop' to handle multiple files, something like  --

It would probably be better if insead of
file.1.eps, file.2.eps, file.3.eps , ... , fileN.eps to write to
file-1.eps, file-2.eps, file-3.eps, ..., file-N.eps.

Some friends tell me that the file generated by metapost is already an

Is there a place where the panics/oops are saved to retrieve them and
cut + paste them here?
/var/log/, /tmp/ ?

Thanks,


Antonio

Re: Why Clang


be more exact.


I believe Robert Bonomi (you didn't include attribution for the previous
email, I notice) *was* more exact, in that the rest of his email
explained what he thought of your glossing over the various factors that
might contribute to binary size.

I notice you ignored most of it in your response, too.


or maybe missed. So please tell me finally what is wrong in measuring 
speed by measuring time of execution doing same things?

What i should measure? time in heavens?



I can generally puzzle out what caused various GCC warning and error
messages when trying to compile my own code, given comparison of what's


strange but i don't have a problem - and i always set -Wall when using gcc 
as 99% of warnings are actually errors.

Re: Why Clang


Sorry, my last header wrongly to Mark Felder,  could give
the wrong impression.  I would like Wojciech Puchar (not Mark F.)
to stop banging on about 'GNU communist licence' etc.


because you don't like facts.
Sorry but i like only facts.

Error in latest KDE4 install attempt

2012-06-18 Thread Lynn Steven Killingsworth

Hi FreeBSD -

This note does not have the proper running commentary since I get hit from
the Internet constantly. The other note on the page is from this past
Friday I think.

At 12a Tuesday (6/19) I decided to try installing KDE4 again. When I
tried to change directory to /x11/kde4 the directory did not exist. I
decided to try to install from my FreeBSD 9 disk at this point. In about
10 sec the install told me that it was unable to install 'qt4-svg-4.7.4'

I then decided to update my ports collection with portsnap. When the
fetch command was downloading the 4 updated metapackages I twice received
this error [snapshot is corrupt gnuzip (stdin)]

I then tried to change directory to /x11/kde4 thinking that since make is
reported to try to fetch the latest files any kde4 would do. I succeeded
and started make. The only option was for the 'better diagnostics'
library. A bison file was fetched and then the installation began using
only files that were found already on my computer.

After a good 15 minutes this appeared:
/usr/ports/devel/qt4-designer/work/qt-everywhere-opensourse-src-4.8.2/lib/QtDesignerComponents.so:
undefined reference to 'QMetaObject: cast (QOject const*) const'

Perhaps this helps.

Thanks - Steve

Hi FreeBSD -

I have just updated my Ports again this morning and I still have the same
problem installing KDE4.

When verifying libphonon.so in /multimedia/phonon [phonon-4.6.0-1][from
the numbers it appears to be KDE4 4.8.4] my machine does not find library
qzeitgeist.1 so it begins verifying the install of qzeitgeist-0.8.0 . The
installer then determines that this version of qzeitgeist is not
compatible.

Since the master site seems to be unavailable much of the time how can I
determine the tar.gz from the version number so that I may have an for
instance //ftp1.freebsd.org/ to put in the the master site change in
the make fetch command?

Thanks - Steve
