Some more information on this crash will be very helpful. What exactly do you see? > I can compile static things with just gfortran but almost anything involving > C++ just fails.

Do I have the right > package? You can install them anywhere, they don't have to be in /usr. You can for instance put them in /mytoolchain or whatever. Then just put /mytoolchain/bin in your PATH, and execute x86_64-pc-mingw32-(toolname) as you have done. If you're using cygwin, you need to use the same version as the cygwint hat you have. I think cygwin updated their runtime dll to a version newer that 1.5.25-12, which is what that particular version you downloaded is compiled against. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
