I'd be rather surprised if that was a goal. DING! We HAVE a winner! The installed libtool has been configured -- by virtue of the fact that I ran the build in a cygwin environment -- to understand cygwin's minutia. It is not intended to work with mingwgcc OR with 'cygwingcc -mno-cygin'. If you want an out-of-box libtool that works with mingwgcc, then use the libtool package distributed by the msys/mingw project. AFAIK, it is not supported to build-your-own libtool with CC=cygwingcc -mno-cygwin ... but it might work. You'd need to do one of the following: (1) download the whole libtool source package, and configure/build/install with CC=...-mno-cygwin, CXX=...-mno-cygwin, etc. Then try to use THAT libtool from your project. or (2) don't call libtool yourself as a platform build tool; instead "libtoolize" your project so that as part of your own project's build process it creates its own local libtool (benefit: this local libtool will use EXACTLY the same settings the rest of your project's build does) If you're already doing #2, see note above concerning "-mno-cygwin not supported". > > OTOH, I never have understood why tools insist on including such things as > "-lcygwin" or "-lc" on a linker command line. There's a good reason for libtool to do so, but it escapes me at the moment.
