IMO priorities for perl should be in order: - getting it linked -lpthread, or get rid of pthread wrapped functions in libc so libpthread can just be a 'normal' library - handling afresh's update to 5.14.2 (not until after 5.3 is tagged) - enabling threaded perl (probably next cycle if possible but with a bit of a delay after 5.14.2) I think they should not be mixed up as otherwise the source of any issues that show up will not be clear. > > > Once perl is built with thread support you won't need this workaround. > > > I'm not sure when this will be done though.

It doesn't but there is no point putting the effort in and not doing so.

There were some issues with rthreads which threaded Perl exposed on alpha but that was fixed awhile ago. AFAIK all of the other archs were fine as is. Its about time this is fixed because this is just getting ridiculous. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

For now, yes. The problem is that perl isn't built with support for threads, while imagemagick is linked to lipthread. Once perl is built with thread support you won't need this workaround. I'm not sure when this will be done though. Someone was working on this some time ago but I don't know how far that effort did go.

ImageMagick and perl
Hello! I was trying to build a piece of software that uses Image::Magick, when I ran into the following problem on amd64 -current: $ perl -e "use Image::Magick;" Can't load '/usr/local/libdata/perl5/site_perl/amd64-openbsd/auto/Image/Magick/Magick.so' for module Image::Magick: Cannot load specified object at /usr/libdata/perl5/amd64-openbsd/5.12.2/DynaLoader.pm line 200. at -e line 1 Compilation failed in require at -e line 1. BEGIN failed--compilation aborted at -e line 1. &Image::Magick::constant not defined. The required ImageMagick libraries are not installed or not installed properly. END failed--call queue aborted at -e line 1. On my another box (i386 5.2) I get another error: % perl -e "use Image::Magick;" perl:/usr/local/lib/libMagickCore.so.3.0: undefined symbol 'pthread_mutexattr_init' lazy binding failed! zsh: segmentation fault (core dumped) perl -e "use Image::Magick;" Is there any way to use Image::Magick on OpenBSD? If no, why does it get built? -- Dmitrij D. Czarkoff
