thanks for reminding..
I am using mac osx leopard 10.5.5

ranlib mylib.a is not generating mylib.lib or mylib

but follow your hint I tried :
libtool mylib.a -o datamodel.lib

then I can get a datamodel.lib

question is that is this way the .lib is done and OK to be used by C++ or
other program later?
