I am trying to build shared libraries under cygwin for mpich 3.0.4 for use in the binary of a parallel application with Python modules (this is why we need shared libraries). Running configure/make/make install produces static libraries even though I configure with --enable-shared --disable-static. This happens with both --enable-sharedlibs=libtool and --enable-sharedlibs=cygwin-gcc. Examining the config.log (attached) seems to indicate there were no errors in the tests/configuration for shared libraries. What configure/make arguments should I use to build shared libraries on cygwin? Thanks, Brad
