At least not out of the box, as it requires "autoreconf" command, which my mingw+msys don't have.
Does anyone know an easy way to build the lib on Windows host, using msys/mingw?
autoreconf just runs autoconf, automake and libtoolize. It's included in the more recent versions of autotools (since 2012 or so). You can run them manually.
I figured this much; that it should be possible to download/install all these missing tools for windows and then run them one after another...
But since I've been struggling to even find the first one from the list, I thought I'd better ask if anyone has actually managed to get through all these steps on Windows.
I figure it is normally built on linux, cross compiled inside gitian.
Perhaps that would be also easier for me.
