Why couldn't you install TortoiseSVN?

However, stackoverflow does have a page [1] that discusses how to still get it. [2] is the link they give for VS2008 Express SP1. [1] http://stackoverflow.com/questions/4482159/where-can-i-download-visual-studio-express-2008-not-2010 [2] http://download.microsoft.com/download/E/8/E/E8EEB394-7F42-4963-A2D8-29559B738298/VS2008ExpressWithSP1ENUX1504728.iso Since you seem to be having so much trouble, I would suggest first getting things to work with Visual Studio 2008 Express. Then once you know how things are *supposed* to work (including looking at the various compiler and linker settings), you can try other build systems. I suppose it would be nice to have some detailed docs on how to build with MinGW but I don't have enough experience to write that. > I've been trying to use MinGW GCC as my current toolchain and CDT > Internal Builder as my current builder within Eclipse.

Alternatively, with Windows Vista & above you can create symbolic links and name them anything you want using the mklink command [3]. For Windows XP you can make hardlinks (which almost act like symbolic links but not quite) using the fsutil command.
