Description Ross Burton 2020-11-05 02:18:05 UTC

Building Go code on the target fails because `go env` contains CC assignments which include --sysroot:

go build runtime/cgo: arm-poky-linux-gnueabi-gcc -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a8 -fstack-protector-strong -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/home/andy/yocto/build/tmp/work/cortexa8hf-neon-poky-linux-gnueabi/go/1.14.7-r0/recipe-sysroot: fork/exec arm-poky-linux-gnueabi-gcc -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a8 -fstack-protector-strong -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/home/andy/yocto/build/tmp/work/cortexa8hf-neon-poky-linux-gnueabi/go/1.14.7-r0/recipe-sysroot: no such file or directory

That's the build sysroot, so obviously shouldn't be used on target.

https://github.com/golang/go/issues/8161 is a related upstream bug, but appears to be saying "the user should work around this" instead of actually fixing the bug.

Not much call for using go on target.

Comment 2 Mark 2022-06-14 20:03:07 UTC

Ross, it appears we can close this issue. I just did a build on master of core-image-minimal with "go" and "go-dev" added to the image. I haven't dug around to see what has changed but to help cleanup the bug backlog when you have a chance could you retest and withdraw the bug if you get similar results?

Good enough for me, thanks Mark.
