How to setup visual studio for cross platform c++ development

Question

After some time mainly .net development, i need to work in c++ in a cross platform manner.

I don't want to give up visual studio, so my hope was that it is possible to use visual studio and the windows target as a testbuild, and then every once in a while through means of a vm test the code on linux or mac.

Does anyone have experience in how to best set this up?

I'm especially curious on how you make sure that things like the project file stay in sync with the make files which are probably needed on the *nix platforms.

Since MS decided to remove support for makefiles from VS, you don't. You use something else that can generate VS project files and make sure you keep THAT set up correctly. Something like CMake.

First of all, select a non-managed c++ project (to avoid the .net stuff).

After that, turn up the warning level (W3 should do), and be very careful what you do/write. IMHO, GCC is better at keeping you straight with the standard (-Wall -Wextra -pedantic -std=c++0x -pedantic), but you specify MSVC.

As Noah said, you'll need build system that is in itself cross-platform, like CMake (there are others, please don't forget that).

Remember to use platform/architecture/compiler independent types, like size_t, (u)intptr_t etc. instead of int, long, unsigned: these are a recipe for disaster and the Windows API throws these around way too much.

See here, but only/especially points 1, 2, 5, and 8 (and 9, but generalize that to svn, git, mercurial).
