Parallel make hangs on 64-bit Cygwin

Parallel make hangs on 64-bit Cygwin

Hi,

 

When trying to build gcc using make with -j N, I'm finding that make will
hang on 64-bit Cygwin. I don't see this problem with 32-bit Cygwin on the
same PC. When it hangs, there are N make processes reported in task manager
that are using 0% CPU, that appear to be waiting for N sh.exe programs also
using 0% CPU. Non parallel builds seem to be OK.

 

Any idea what might be wrong? Cygwin install is up to date. Windows 10.

 

Thanks,

Jon

There was a discussion on the matter on the packager mailing list in February
https://cygwin.com/pipermail/cygwin-apps/2023-February/042624.html

Please try the test version of the package
https://cygwin.com/pipermail/cygwin-announce/2023-March/010972.html

and let us know it the 4.4.1-2 version solves your problem

Thanks. I did search, but it seems Google's index doesn't include that thread: https://www.google.com/search?q=%22Heads+up%3A+Problems+with+parallel+make%22+site%3Ahttps%3A%2F%2Fcygwin.com%2F

Current version of make (4.4.1-1) with  --jobserver-style=pipe works and the test build 4.4.1-2 works without needing that option. Thanks.

Cheers,
Jon
