Re: Make spins with THREADS>1 on Win 7

Ah, I've forgotten to mention that the environment variable MSYSTEM must be set to MINGW before starting the shell as is in mingw_shell.bat: set MSYSTEM=MINGW. msys2_shell.bat set it to MSYS thus making it answer "msys". On Wed, Oct 2, 2013 at 1:59 AM, Simon Peyton-Jones wrote:

Interesting! There appears to be about zero documentation, but I unpacked the tar ball (which has pre-built binaries), put it in c:/msys32, added c:/mys32/bin to my PATH, and tried.****

Yes; it appears that in the current MSYS release, 'make -jn' goes into an infinite loop. This is very depressing. I do not know a fix.

If you google around and find a fix, do tell us. Currently I have to use THREADS=1 all the time
