How to compile .c .h .so file?

Question

Another company gives me three files(demo.c,api.h,libapi.so). they told me that't enough for develop. I'm confuse how to build these thing together. I use gcc demo.c -o demo -l libapi.so . But's it's said "ld: library not found". I use Mac OS system. Some websites said i should use Linux to use .so file. what should I do?

Answer 1

*.so is "shared object" it works only on Linux. The Windows counterpart of *.so is DLL.These are combiled object code.

What you have to do is 1] "compile" your .c to .o [object file] 2] "Link" the new .o file with the .so
