I feel like this is somewhat dependent on #37443, which I stalled out on. |
|
@ianlancetaylor I just submitted a PR for that |
|
I see that now, thanks for working on it. |

Add the generated structure definitions for linux/ppc. This file was
created using gccgo 10.2.1 and the command:
GOARCH=ppc CC=powerpc-linux-gnu-gcc go tool cgo -godefs defs_linux.go
Fixes golang/go#45677

What version of Go are you using (
go version)?Does this issue reproduce with the latest release?
Not tested, but the master branch of the net repository is still missing support for linux/ppc.
What operating system and processor architecture are you using (
go env)?go envOutputWhat did you do?
Used a fork of
x/sysfrom golang/sys#106, which adds support for linux/ppc. Tried to build a trivial test program:What did you expect to see?
This should build successfully.
I have local changes to fix this and will open a PR shortly.
What did you see instead?
