Question

i have downloaded a C library from the net with the name libsal.a, to access the APIs in that library i include a header file by name #include in my main.c. i use the following command to compile it :

gcc -L /home/traana/Desktop/opensal-1.0.0/libsal.a main.c

but get the following error when i compile

main.c:3:17: fatal error: sal.h: No such file or directory
compilation terminated.

How do I do this correctly?

Answer 1

When compiling your source, it’s not the library, but the include files that are relevant; so you’ll need to tell gcc where those are, something like

gcc -c -I/home/traana/Desktop/opensal-1.0.0/include main.c

and then link the application with something like

gcc -L/home/traana/Desktop/opensal-1.0.0 -lsal main.o
