Description Necktwi Ozfguah 2022-01-24 06:00:26 UTC

cross build of gcc-11.2.1_p20211127 has failed with following build log:
```
# wgetpaste -s sprunge /usr/aarch64-unknown-linux-musl/tmp/portage/sys-devel/gcc-11.2.1_p20211127/temp/build.log
Your paste can be seen here: http://sprunge.us/stedwj
```

Before this I tried cross merging `gcc-11.2.0`, `gcc-10.3.0-r2` and `gcc-9.4.0` which all failed.

Please attach in future as external paste sites may expire.

I'm wondering how you can hit this and I can't :(

Could you give some steps from a clean stage3 with crossdev, perhaps?

You're building with gcc 8.5 which lacks __has_builtin. Please try a newer GCC on the host?

Comment 3 Necktwi Ozfguah 2022-01-25 17:07:05 UTC

yes, able to merge aarch64-gcc-10 with cross-aarch64-gcc-11.
