Trying to use PerlMagick modules gives me: Can't load '/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux/auto/Image/Magick/Magick.so' for module Image::Magick: libgomp.so.1: shared object cannot be dlopen()ed at /usr/lib64/perl5/5.8.8/x86_64-linux/DynaLoader.pm line 230. This appears to be the same bug as 193737, which was closed several months ago. I'm not positive, but I think the upgrade to GCC 4.2.4 was the instigating factor. Reproducible: Always Steps to Reproduce: 1. Use PerlMagick library. 2. Boom. Actual Results: Error message as above. Expected Results: PerlMagick should link.

Which version of media-gfx/imagemagick do you use?
I experience the same error with imagemagick wrapper for ruby (Rmagick) on two computers - i686 and x86_64. libgomp.so.1: shared object cannot be dlopen()ed - /usr/lib64/ruby/site_ruby/1.8/x86_64-linux/RMagick2.so I belivele it caused by libgomp.so from news GCC (updated just yesterday). Found a thread that seems relevant to the problem: http://www.archivum.info/gnu.gcc.help/2006-07/msg00076.html

from what i see the problem is that libgomp.so in gcc 4.2.4 (didn't check earlier versions) is marked NOOPEN so it can't be dlopen'd, directly or indirectly. perl/ruby/apache+php/etc all dlopen their modules and since imagemagick libs link against libgomp, such attempts fail. so there're two questions to answer: - is imagemagick supposed to link against libgomp? if yes, then there's trouble because it means that imagemagick cannot be used as a dlopen'd module any longer. if no then something in the imagemagick build system (or maybe default gcc specs?) pulls it in for no reason. - is libgomp marked NOOPEN for any particular reason? was it like that before? in any case, if the answer is yes (and i guess it is), then it means that nothing linking against it can be dlopen'd in the future, so more packages besides imagemagick will break.
(In reply to comment #6) > so there're two questions to answer: Thanks for figuring out NOOPEN as the culprit! I guess the answer to both questions is "No, but there is a performance penalty if you don't". For imagemagick, the solution would be to --disable-openmp. I guess introducing the openmp USE flag and $(enable_with openmp) would be more appropriate. Maybe using perl or python should override the openmp setting, though. As php is probably affected as well, and is in a separate package, the current IUSE flags are not enough to decide whether imagemagick has to be dynamically linkable. For the NOOPEN flag in libgomp I found a most interesting bug report here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28482 There is a fix included in gcc-4.3*, but 4.2.4 doesn't include that fix. Maybe 4.2.5 will. So here a workaround for Gentoo users would be to emerge and switch to the latest gcc, with all the system rebuild that entails.
Created attachment 157333 [details, diff] openmp USE flag for imagemagick This patch allows users to add "media-gfx/imagemagick -openmp" to their /etc/portage/package.use in order to avoid linking against libgomp. A matching entry in profiles/use.local.desc would probably be required as well, e.g. copy&paste from gcc. profiles/default/linux/make.default currently defaults openmp, so the patch wouldn't affect the default behaviour.
USE-flag added in media-gfx/imagemagick-6.4.2.0. Thanks for the patch.
I upgraded to GCC 4.3.3 and then emerge imagemagick failed: /usr/lib/gcc/i686-pc-linux-gnu/4.3.3/libgomp.la: line 41: libdir/usr/lib/gcc/i686-pc-linux-gnu/4.3.3: No such file or directory /usr/lib/gcc/i686-pc-linux-gnu/4.3.3/libgomp.la: line 41: libdir/usr/lib/gcc/i686-pc-linux-gnu/4.3.3: No such file or directory libtool: link: warning: library `/usr/lib/gcc/i686-pc-linux-gnu/4.3.3/libgomp.la' was moved. /usr/bin/nm: '/usr/lib/gcc/i686-pc-linux-gnu/4.3.3/.libs/libgomp.a': No such file i686-pc-linux-gnu-gcc: /usr/lib/gcc/i686-pc-linux-gnu/4.3.3/.libs/libgomp.a: No such file or directory Note that there is actually a file "called /usr/lib/gcc/i686-pc-linux-gnu/4.3.3/libgomp.la".

(In reply to comment #10) > libdir/usr/lib/gcc/i686-pc-linux-gnu/4.3.3: No such file or directory Sounds like bug 256636, caused by bug 125728 comment 162, and fixed here: http://sources.gentoo.org/eclass/toolchain.eclass?r1=1.385&r2=1.386 Try to sync, remerge gcc, emerge imagemagick, and see if that works.

As per bug 256636, I recompiled GCC 4.3.2-r3 because toolchain.eclass had changed. This fixes the problem.
