cannot build +universal version of libpano13 on Snow Leopard

[turkowski]

I canot cannot build +universal version of libpano13 on Snow Leopard. It seems to compile without +universal, though.

% sudo port -d install libpano13 +universal

Please remember to preview and use WikiFormatting, fill in the Port field, and cc the maintainer.

Patch to pass -arch flags through libtool

[jvansanten@…]

Patch to Portfile to patch config/ltmain.sh

[jvansanten@…]

This version of libpano uses an ancient version of libtool that doesn't pass through -arch flags when making shared libraries (see ​this discussion). I've added a monkey-patch for config/ltmain.sh that makes it work properly. Someone with commit access should modify the Portfile, I suppose.

[ryandesign (Ryan Carsten Schmidt)]

An alternate solution is proposed in #25828. The maintainer should pick one.

[hvdwolf@…]

Both this patch and the patch mentioned in #25828 are now outdated. This patch as such works OK. The patch in #26447 works with the new 2.9.17 library (which is a big enhancement over the old 2.9.14 and is necessary for newer versions of hugin). I adapted this patch to work with 2.9.17 and uploaded that as an alternative patch to that same #26447 ticket. Please use one of both patches attached now to #26447 instead of this patch for 2.9.14

[ryandesign (Ryan Carsten Schmidt)]

Addressed by #26447.
