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.

 

Regards,
