Cross compiling is a general problem and not related to a specific distro. For your specific problem: it is most unlikely that you will get a MS cross compiler that runs on other platforms than WIN-DOS. In general: The most annoying problem with cross compiling is that GNU autoconf does not support cross compiling and as a result, you need to manually create results if you like to cross compile. The reason for this problem is that many autoconf tests need to be run on the target platform in order to create useful results. Since July 2011, the Schily autoconf system (available e.g. via: ftp://ftp.berlios.de/pub/schily) includes support for cross compiling by detecting cross compilation and by running those tests that need the target system either on a related target system or on an emulator. Note that the autoconf configuration in ftp://ftp.berlios.de/pub/schily includes aprox. 700 autoconf tests - 70 of these tests need to be run on the target, this can be seen as a hint that aprox. 10% of the tests need to be run on the target.

This has been used to cross compile many 32 bit applications from Debian for W32, from what I understand. I have managed to cross compile bzip2, lame, libogg, libvorbis, vorbis-tools, and a few others - they all work. With most, I only needed to set the correct path (to mingw), and specify the tools and target and run the configure script. I ran into problems with gzip and zlib, however.

The really annoying thing for me is that if you look at the Mingw64 site on sourceforge, they indicate that you can cross compile from a GNU/Linux distribution to W32 or W64 - and they give a list of apps that were successfully cross compiled, but little in the way of documentation.

For your specific problem: it is most unlikely that you will get a MS cross compiler that runs on other platforms than WIN-DOS. I've had very good luck with gcc's x86_64-w64-mingw32 target, and gcc has supported Win32 builds for years, so I dunno why you think this is unlikely. My biggest problem with MingW has been their occasional lag behind gcc in versions, but I believe gcc 4.5 can cross-compile for 64-bit Windows. The setup is rather a pain but then again, if you wanted easy, you probably wouldn't be using Gentoo :) http://sourceforge.net/apps/trac/mingw-w64/wiki/Cross%20Win32%20and%20Win64%20compiler For the OP's specific problem, I'll have to try and build GraphicsMagick on Gentoo and see what kind of build structure is uses that is giving him problems but its possible he just needs xbuild (the Mono msbuild implementation.) Worst case it has an old VC++-style workspace but those are usually just auto-generated out of the makefiles anyway. --Mike

Mingw might not be reallly 'embedded' but that list would still be the most relevant place to ask gentoo-related crosscompile questions... Gentoo also has a crossdev tool that should also support mingw, though I only ever used it for i686 and arm crosscompiles. yoyo

GNU autoconf allows to set up default results for cross compiling when trying to test things that need to run on the target. Some of the basic GNU text utils either return most pessimistic values in case of a cross compilation or someone did handcraft the related results for MinGW and publishes such a modified source that probably will no longer compile correctly on other systems. BTW: I introduced the cross compilation extensions to schily autoconmf in order to permit to compile my software for android.

Be careful microsofts nmake is not compatible to nmake nmake has been written by David Korn and Glenn Fowler in the mid 1980s. Microsoft much later resused the name for something non-compatible. It does not make sense to look at the MS nmake syntay as it is completely non-portable.

While I program a lot on my Linux machines, I haven't actually found an IDE that doesn't make me wish VS ran on Linux. MonoDevelop isn't horrible but if I wanted to write .NET code I'd just use Windows; Eclipse makes me want to drill my brain out with a corkscrew and the only other decent IDE's I've seen are KDE-specific. I've falling back to the default of Emacs at this point; it's powerful enough, especially when I'm doing Lisp or Scheme, but I have an internal mental limit of 150,110 hotkey combinations that I think is holding me back. If you have any suggestions I'm all ears :) As for the types of files I've seen, I have seen both VS Solution/Project files, and nmake files.

Also, do you have a link for Visual C++ Express? I like to do most programming in C/C++ anyway (though this is OT). Well, if you're willing to go the install a Windows OS route, everything you need command-line wise is found in the Windows SDK: http://msdn.microsoft.com/en-us/windowsserver/bb980924.aspx. Visual C++ 2010 Express can be downloaded from: http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express Mostly what you lose with Express are the TFS integrations, unit testing, and other application lifecycle management stuff they pack into the full editions. Express editions can't build debug 64-bit applications, but the 64-bit compilers come with the SDK. Depends on how much effort you're willing to put into it. If you don't want to install Windows you're options are going to be mostly limited to the GNU binutils and GCC, which support targeting Win32 and Win64. In theory you could run the command-line tools, for example, under Wine, but I've never tried it. I don't actually know of a make for Linux that is compatible with NMAKE. If you can't find one then you'll need to do a lot of work to build any applications that require it. However, I think the number of applications using Microsoft make files is vanishingly small: they're either going to produce a GNU makefile (since GNU make runs on Windows) or an MSBuild project. And yes, ATT also released a tool called nmake that is not compatible with Microsoft NMAKE (or either of the other two incompatible makes), so don't get them confused. --Mike
