Thanks, it indeed does. I had to leave out -fPIC. I'm curious, why did
that cause a problem?

Last question; is the first method expected to also work on Mac, with
the linker replaced by the appropriate linker for Mac, if I'm using
gcc et al to build? I.e.:

const char my_interp[] __attribute__((section(".interp"))) = "<dyld path>";

(...)

gcc -Wall -fPIC -shared -o library.so test.c -lc -Wl,-e,my_main

In other words, does gcc on Mac support executable shared libraries?

Thanks,
Mayank
