Hello, I was trying to add a function to dgif_lib.c. First just a test-function. After compiling and reinstalling the giflib, my function is in gif_lib.h in the /include dir. But i get a symbol look up error for this function when calling it. What's the correct way to make a function in gif_lib.h? Thanks Alex |
