Noted. Thanks. Will install to /usr/local once configure script runs.

I have narrow down the problem with the following test program:

#include <stdio.h>

char oggpack_writealign ();

int
main ()
{
 return oggpack_writealign ();
 return 0;
}

LD_LIBRARY_PATH='/usr/lib' clang oggpack.c -DDARWIN -fno-common -force_cpusubtype_ALL -Wall -g -O3 -ffast-math -fsigned-char -Wdeclaration-after-statement  -DUSE_MEMORY_H -I/usr/include -logg -lpthread -o oggpack

ld: library not found for -logg
clang: error: linker command failed with exit code 1 (use -v to see invocation)


clang oggpack.c -DDARWIN -fno-common -force_cpusubtype_ALL -Wall -g -O3 -ffast-math -fsigned-char -Wdeclaration-after-statement  -DUSE_MEMORY_H -I/usr/include /usr/lib/libogg.dylib -lpthread -o oggpack

No error.

ls -l /usr/lib/ | grep ogg
-rwxr-xr-x   1 root    wheel    31336 Apr 20 18:37 libogg.0.dylib
lrwxr-xr-x   1 root    wheel       14 Apr 20 18:37 libogg.dylib -> libogg.0.dylib

ls -l /usr/lib/ | grep pthread
lrwxr-xr-x   1 root    wheel       15 Apr 12 11:58 libpthread.dylib -> libSystem.dylib

This seems -logg does not look for /usr/lib/libogg.dylib !

Any idea why?
