I've a program which links to many libraries. g++, by default, prefers to link to shared libraries, even if the corresponding archive exists.

How can I change this preference to prefer static archives over dynamic libraries, if a static archive exists?

Note, I used -static option, but it tries to find static archive for all libraries which is not what I want.

g++ -Wl,-Bstatic -lz -lfoo -Wl,-Bdynamic -lbar -Wl,--as-needed

Will link zlib and libfoo as static, and libbar as dynamic . --as-needed will drop any unused dynamic library.
