On which platform?

On Linux you can do this:

  # combine libbar.a and libbaz.a into libfoo.so
  g++ -fPIC -shared -o libfoo.so -Wl,--whole-archive -lbar -lbaz 
-Wl,--no-whole-archive

On non-GNU-ld platforms you have to "explode" the archives:

  mkdir tmp.$$ && cd tmp.$$ &&
  ar x ../libbar.a && ar x ../libbaz.a &&
  g++ -fPIC -shared -o ../libfoo.so *.o && 
  cd .. && rm -rf tmp.$$
