I'm looking to add support for a non-Windows platform for Visual Studio 2008. It would need to build C++ using a non-Microsoft toolchain (essentially a customised gcc).
I know the easy way is to use a Makefile project, but I'd at least like to explore adding support for a new toolchain directly to VS. I know it is possible; MS do it, with their Windows CE toolchain (and provide Platform Builder to allow CE device manufacturers to customise it) and Intel do it with their C++ and Fortran compilers.
I can't find any documentation on it, though, or even any hint from the documentation that it is possible. Can someone point me towards some documentation that will at least give me a starting point?
