Bug 719934 – dev-python/pycparser calls cpp directly

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Agostino Sarubbo 2020-04-28 14:39:55 UTC]

This is an auto-filled bug because dev-python/pycparser calls cpp directly.
The issue was originally discovered on arm64, but it may be reproducible on other arches as well.
If you think that a different summary clarifies the issue better, feel free to change it.
Attached build log and emerge --info.

NOTE:
This issue has been reproduced by setting the CPP variable and by removing the /usr/bin/cpp binary.

This doesn't seem like a real problem. pycparser optionally uses 'cpp' to parse header files. It doesn't compile anything, so using the ${CHOST} toolchain does not matter.

[Comment 3 Agostino Sarubbo 2020-04-28 17:05:31 UTC]

I guess it does matter if I use a different cpp implementation (e.g. clang-cpp after set CPP)

[Comment 4 Mike Gilbert 2020-04-28 17:31:33 UTC]

It should work with any cpp that can process C99 source files.
