[x264-devel] [PATCH] Fix shared libs on MacOSX

[Gregor Riepl]

unfortunately, this is no solution if you want to build x264 for a pre- 
leopard osx.
afaik, the bug lies in gcc indeed, and i think it's been known for  
some time.
if i remember correctly, some xine developer has written a workaround  
to a similar problem. i'll try to look it up.

thanks for your patch, i found a little bug in it though:
     echo "SONAME=libx264.$SOEXT.$API" >> config.mak

this works for elf based systems, but for mach-o, the version is  
usually in front of .dylib, not after.
the patch should say (for example):
      API=$(grep '#define X264_BUILD' < x264.h | cut -f 3 -d ' ')
-    echo "SONAME=libx264.so.$API" >> config.mak
+    if [ $SYS = MACOSX ]; then
+        SOEXT="dylib"
+        echo "SONAME=libx264.$API.$SOEXT" >> config.mak
+    else
+        SOEXT="so"
+        echo "SONAME=libx264.$SOEXT.$API" >> config.mak
+    fi
+    echo "SOEXT=$SOEXT" >> config.mak
