if I have a file with 3 function in and I only use one how can I compile the exe so it only includes the code for the functions I call , do I need certain command line options to GCC ie. I have the following three files and only want first(), thanks in advance Simon... -------------------------- testmain.c -------------------------- #include "test.h" int main(void){ first(); return(0); } -------------------------- test.h -------------------------- void first(void); void second(void); void third(void); -------------------------- test.c -------------------------- void first(void){ int x; x=0x37; } void second(void){ int x; x=0x37; } void third(void){ int x; x=0x37; } --------------------------
