Xcross87 Posted May 9, 2009 Report Share Posted May 9, 2009 I have a little problem like this. I put: my_header.h in /usr/local/include/mylib and its libraries in /usr/local/lib/mylib And then I write a small C script like this: /* source.c */ #include <mylib/my_header.h> int main() { my_function(); return 0; } I compile it: shell> gcc -o run source.c and got error: undefined reference to 'my_funtion' what happened? Can some1 explain and gimme solution? Tks so much. Quote Link to comment Share on other sites More sharing options...
ilia_kr Posted May 9, 2009 Report Share Posted May 9, 2009 You have to tell a linker where to look for your lib file. Try adding -lmylib to gcc command. Quote Link to comment Share on other sites More sharing options...
