The problem is that crossdev can generate a C cross-compiler for i686-pc-mingw32 or i586-mingw32msvc adaquetely enough to produce apparently correct code, but the name handling certainly isn't correct. I'm not sure if this is necessarily more of a problem of portage (though binutils apparently doesn't append .exe by default) with trying to emerge things for it, but for instance, on my AMD64-based Gentoo installation, you can get files like this: /usr/i586-mingw32msvc/lib64/libz.so.1.2.3: MS-DOS executable PE for MS Windows (DLL) (console) Intel 80386 32-bit for: CHOST=i586-pc-mingw32 CFLAGS="-march=i586 -pipe -O3 -ffast-math" ROOT=/usr/i586-mingw32msvc emerge zlib, which I'm told is the correct way to do it. Also, because base libraries and other things are already precompiled for MingW, and it doesn't support glibc (or newlib, uclibc, et cetera), it means that glibc and linux-headers aren't support for it, which means you can't install a C++ cross-compiler, either. IIRC, static versions of libraries should be libz.a, for instance, with shared linkable being libz.dll.a or just linking against libz.dll. I know conventional wisdom would be to download and use xmingw, but those are somewhat out of date comparatively, the only 'additional' step should be putting mingw-runtime and w32api tarballs into the target directory before making the cross-compiler, which I can do easily, but using portage+crossdev, I should reasonably be able to get a nicely working target (and emerge support for compatible things) for cross-compilation with it. That's mostly compatible with a large number of things, including the very libraries that I'd need to be able to compile my projects with. vapier@gentoo.org 2006-04-11 10:11:27 0000 i mentioned this already but i have no urge to investigate how to integrate it cretin@gentoo.org 2006-04-11 11:40:58 0000 Hi, I'll see. Strangle I was just trying to update the dev-util/xmingw-* ebuild today and yesterday. I would first have to look into the crossdev process to see if it can do the special things needed for xmingw vapier@gentoo.org 2006-09-17 00:09:05 0000 ive just gone ahead and done this myself ;) # crossdev mingw32 -------------------------------------------------------------------------------- * Host Portage ARCH: amd64 * Target Portage ARCH: amd64 * Target System: mingw32 * Stage: 4 (C/C++ compiler) * binutils: binutils-[latest] * gcc: gcc-[latest] * headers: w32api-[latest] * libc: mingw-runtime-[latest] * PORTDIR_OVERLAY: /usr/local/portage * PORT_LOGDIR: /var/log/portage * PKGDIR: /usr/portage/packages/cross/mingw32 * PORTAGE_TMPDIR: /var/tmp/cross/mingw32 _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - * Using dev-util/w32api from /usr/local/portage instead of /usr/portage * Using dev-util/mingw-runtime from /usr/local/portage instead of /usr/portage * Forcing the latest versions of binutils-config/gcc-config ...
