I tried the --disable-static option (I believe for a static convenience library, I should use the --disable-shared option?), but libtool doesn't recognize it:
  libtool: unrecognized option '--disable-static'
the command i tried is:
  libtool --disable-static --mode=compile g++ -g -pipe -c file.cpp
  libtool --mode=compile --disable-static g++ -g -pipe -c file.cpp
  libtool --mode=compile g++
--disable-static -g -pipe -c file.cpp
