libsdl +no_x11: sdl-config omits -Wl,-framework,Cocoa from libs

[realnc (Nikos Chantziaras)]

smpeg can't be built. libsdl has been built with +no_x11. log attached.

This is on OS X 10.6.4, XCode 3.2.4.

I am attaching the full log, but the errors have this form:

:info:build   ".objc_class_name_NSProcessInfo", referenced from:
:info:build       literal-pointer@__OBJC@__cls_refs@NSProcessInfo in libSDLmain.a(SDLMain.o)
[...]
:info:build       _main in libSDLmain.a(SDLMain.o)
:info:build       _main in libSDLmain.a(SDLMain.o)
:info:build       _main in libSDLmain.a(SDLMain.o)
[etc, etc]

This could as well be an issue with libsdl. What does the following command print on your system?

$ sdl-config --cflags --libs

On my Mac OS X 10.6.4 with libsdl @1.2.14_8+universal (build_arch x86_64), this results in:

-I/opt/local/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE
-L/opt/local/lib -lSDLmain -lSDL -Wl,-framework,Cocoa

In your attached log file I don't see any mention of Cocoa, which makes me wonder if SDL might be reporting wrong flags.

[realnc (Nikos Chantziaras)]

"-Wl,-framework,Cocoa" is indeed missing from sdl-config's output:

$ sdl-config --cflags --libs
-I/opt/local/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE
-L/opt/local/lib -lSDLmain -lSDL

I edited the sdl-config script manually and put "-Wl,-framework,Cocoa" at the end. After that, smpeg builds fine.

If you're trying to reproduce, I've built libsdl with "+no_x11 +universal" and my macports.conf has these settings:

build_arch        i386
universal_archs   i386 ppc
