If I run
gcc a.c -L /usr/lib -lexpat
and both libexpat.a and libexpat.so are in /usr lib which one is used by the linker?
回答1:
By default the shared library (.so) will be chosen.
If you want to change this behavior, -static gcc option may be used
-static
On systems that support dynamic linking, this prevents linking with the shared libraries. On other systems, this option has no effect.
