>Description:
compiling the attached test normally with:
gcc prof_test.c `sdl11-config --cflags --libs`
works fine. but if you want to add profiling support with:
gcc -pg prof_test.c `sdl11-config --cflags --libs`
it will give a bunch of linking errors. adding '-lc' will
fix the linking errors, but will core dump when run because of
the linking order. adding '-lpthread -lc' is the only way to
have it link and run without any problems.
i believe this is a bug, i don't see how profiling should
change the behaviour of linking.
>How-To-Repeat:
try to compile the attached test with:
gcc -pg prof_test.c `sdl11-config --cflags --libs`
>Fix:
--- prof_test.c begins here ---
#include "SDL11/SDL.h"
int main()
{
SDL_Init(SDL_INIT_TIMER);
return 0;
}
--- prof_test.c ends here ---
