how to force linker to use shared library instead of static library?

Question

This is a quote from Linux programming book:

---

% gcc -o app app.o -L. –ltest

Suppose that both libtest.

Answer 1

You could use -l option in its form -l:filename if your linker supports it (older versions of ld didn't)

gcc -o app app.o -L. -l:libtest.so

Other option is to use the filename directly without -l and -L

gcc -o app app.o /path/to/library/libtest.so
