I use code::blocks to compile my static library. The output result is a libstatic.a file. Now, how do I link to my library to use functions that were compiled?
(I tried to use #include "libstatic.a" but my project doesn't compile)
cc -o yourprog yourprog.c -lstatic
or
cc -o yourprog yourprog.c libstatic.a
You should #include "libstatic.h", i.e. use the appropriate header file in your code (that's why your code doesn't compile) and include the path to your libstatic.a in the linker options as one of your input libraries.
This webpage has some examples on linking to a static library, e.g.
gcc -I. -o jvct jvct.c libjvc.a
I had to set the library path in my makefile. For this case you could use:
gcc -o myapp main.c -L. -lstatic
HMS
gcc -I. -o jvct jvct.c libjvc.a
To link purely statically, use -static
cc -static yourprogram.c libstatic.a
