Re: make -jN loops on Windows

Hi! I have a hint of what could be wrong. I looked through my configuration and saw that I used integer-simple. When I changed it to integer-gmp it blew up with -j4 (it didn't hang though, it errored out in the linking phase). The build went fine after I reran without -j. Niklas 2013/8/28 Simon Peyton-Jones

I tried make –j2, which locked up. “sh validate” used –j but I’m not sure with what N.****

It’s tantalising if it worked for you! And it worked fine on my old Win7 laptop. Where did you get your mingw/msys installation from? I got mine from http://www.mingw.org/, using the download installer “Mingw-get-setup.exe”.****

** **

I have also just unravelled another bizarre failure, which I’ll describe in a separate email. Sadly resolving the latter does not fix the make –j2 problem.****

Hi!****

** **

Are you using make -j with or without number of jobs? I tried with make -j4 on my Windows 8 machine and it worked well.****

Hi Simon,****

** **

I think this is a MinGW bug. If we're talking about the same bug (lockup, no console output, task manager shows cpu but it doesn't produce files, etc) I get it when building other projects with -j too and I don't think its GHC's fault.****
