As title. I think 1) There should be a CMakeFiles.txt in MPIR downloaded package that makes MPIR automatically work on whatever platform that CMake supports. 2) If not, it's ok to open the provided VS solution and build MPIR. But the consequence is a lot of errors inside Visual Studio. 3) Why not just provide a one-fits-all (or at least 90%) pre-compiled binary for Windows? It doesn't make too much sense for many different users to compile the same source again and again in different part of the planet but get exactly the same output. 4) just a personal opinion, Windows is Windows. Linux is Linux. If one have to use Linux, why not go straightly to Linux (dual system, VMware workstation, or just a stand-alone Linux machine) but use CygWin in Windows? I don't understand. 5) I've read the manual. It seems to me only changed all GMP to MPIR, all Linux stuff. command lines, strange options, so I still don't know how to install MPIR.
So, do I have to use CygWin or the like to install MPIR?
