Hi Tamas. Yes, you're right. I was missing the "make clean". Also, the right command for configure is ./configure --prefix=C:/MinGW64 --host=x86_64-w64-mingw32, assuming that your MinGW64 is installed in C:\MinGW64.
I'm doing some tests comparing the performance of 32 and 64 versions of my code and surprisingly, the 64 version is much slower. My code basically compute tons of shortest paths. Is that reasonable for you?
