ninja --version returns a nonzero error code in a shell on Linux.

[WarrenWeckesser]

I just upgraded to 1.11.1, and I get a nonzero return code when I run ninja --version:

$ ninja --version
1.11.1.git.kitware.jobserver-1
$ echo $?
245

This is on a Linux system.

With 1.10.2.4, the return code is 0, as expected:

$ ninja --version
1.10.2.git.kitware.jobserver-1
$ echo $?
0

This breaks meson, which expects the return code of ninja --version to be 0. And the failure of meson breaks the builds any package that depend on meson. I noticed this because the CI builds of SciPy are currently failing.

Note that the ninja project itself doesn't actually release those PyPI binaries, it's done totally unofficially by a third-party project that also adds various patches.

On a fresh clone and build of ninja:

$ ./ninja --version
1.12.0.git
$ echo $?
0

So the bug was most likely introduced downstream... see scikit-build/ninja-python-distributions#157

I'll close this, as it is a duplicate of #2211.

Can you retry? I uploaded a manylinux2010 wheel for 64-bit Intel.
