Suppose I have a file main.cpp which uses sin() function which is defined in libmath. Also suppose that we have both libmath.a and libmath.so available in the same directory. Now if I issue the command g++ -o main main.cpp -lmath the default behaviour of Linux is to link to the shared library libmath.so. I want to know is there a way to force the program to link with the static library libmath.a without deleting or moving the shared library?

You'll need to pass the -static to the linker, but only for particular libraries you want. e.g.:
g++ -o main main.cpp -Wl,-Bstatic -lmath -Wl,-Bdynamic

Surely it shouldn't matter for gcc/binutils, -static and -Bstatic are synonyms in the GNU linker.
If your linker supports -l:<filename> you may use:
g++ -o main main.cpp -l:libmath.a

Use this function:
g++ -o main main.cpp /path_to/libmath.a
