+## Building on MSYS2
+
+1. Install PothosSDR to `C:\PothosSDR\` and install MSYS2.
+> The PothosSDR path can't have spaces in it because the MinGW gcc
+doesn't recognize Windows style paths with escaped spaces in them
+which is what the pkg-config returns.
+2. Remove the following headers `pthread.h, semaphore.h, sched.h` from `<PothosSDR root>/include`.
+> MSYS2 already has these POSIX headers and we need the compiler to use the default headers.
+
+#### Building with MinGW-w64
