Hi, Maybe I could try to set up MSVS 2012 tomorrow in a virtual machine with 64-bit Win7 and see if I can reproduce the problem. It is clear that the relax sconstruct script is pointing to all the correct locations. If you type out the compiler commands by hand, they should just work. Therefore the problem is very unlikely to be with relax itself, but rather with the Microsoft 2012 C++ toolchain and/or its interaction with IPython. I'm wondering if it is a 64 vs. 32-bit mismatch issue. Do you have a 64-bit Windows install? Is the compiler toolchain (MSVS) 64-bit? Is the Python version bundled with IPython 64-bit? I really hope the issue is not because IPython is incompatible with MSVS! I think we are narrowing the problem down a bit and we should get to the bottom of it soon. For me replicating the issue, could you list the exact version and bit number of the operating system, MSVS, and IPython.
