That's why I said it would have been sufficient to say "There was no issue that I could find in the project cfg, see if the toolchain executables are actually able to compile 64bit code", I did not ask you to solve the problem if it was not a cfg issue but rather check to see if it was a cfg issue or just me missing something in the documentation. I never expected you to research any compiler or linker stuff just to check whether something in xml was causing my problem, if you found an issue there then that's all I expected you to help me with. Anything further, while nice, was not within my expectations.
