Yes, ImageMagick uses OpenEXR like that. And the ImageMagick's /executables/
(such as display, convert, identify, etc.) are linked correctly.
But -- because perl does not have threads by default on FreeBSD -- PerlMagick
does not work. This is a known problem -- and not only with Perl. The only
solution for -stable is to not use -threads wherever possible... This is why
I'm asking, if it is, indeed, possible to turn multi-threading off in OpenEXR
Seems like it is... Please, make threading optional in the new version (1.6.0)
of OpenEXR port.
= And I'll update OpenEXR to 1.6.0. Thanks for your remind.
The update will, probably, require splitting the port in two -- the ilmbase is
now released separately and contains libHalf, libIlmBase, libIlmMath. The
actual graphics library remains in OpenEXR.
By the time your e-mail arrived I almost finished the port of ilmbase. I'm
attaching it here -- only the pkg-plist may need re-verification. The port
needs to be committed together with the matching OpenEXR update.
The dependant ports may need to revisit their dependencies -- those, who need
only libHalf will need to depend on devel/ilmbase instead of the full-blown
OpenEXR, for example.
