BUG: MPlayer-1.0rc1 fails to build with +fontconfig - libexpat and isysroot issue

[yunzheng.hu@…]

when building mplayer with the +fontconfig variant it will bork on the following compilation error:

This is probably because libexpat and fontconfig is also in the SDK of Mac OS X and the configure of mplayer sets: "-isysroot /Developer/SDKs/MacOSX10.4u.sdk"

removing the -isysroot will make the compilation successful but i'm not sure if this is the best solution. The problem might also lie in 'fontconfig' as that depends on 'expat' which both come with the Mac OS X SDK:

/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib/libexpat.0.4.dylib /Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib/libexpat.a /Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib/libfontconfig.1.0.dylib /Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib/libfontconfig.a

which probably conflicts with (when using isysroot): /opt/local/lib/libexpat.1.5.0.dylib /opt/local/lib/libfontconfig.1.2.0.dylib

the patch that removes the -isysroot from mplayer's configure: ​http://paste.lisp.org/display/37698 (credits for finding the bug goes to: Arno Hautala (see annotion 1)

it also seems this is fixed in the mplayer svn.
