with -trimpath option with go install with muslc on default alpine linux, the go install doesn't work.
apk add --no-cache build-base can be executed as workaround before (but, we have to do each time on CI).

What version of Go are you using (go version)?

go 1.17.5

What did you do?

on our CI, with alpine linux:

  • go install ./...

What did you see instead?

# runtime/cgo
cgo: C compiler "gcc" not found: exec: "gcc": executable file not found in $PATH

cgo needs a C compiler is needed to build C code, this is working as expected.

If you prefer to disable cgo, you can configure that with the CGO_ENABLED environment option.

If your C compiler command is not "gcc", you can configure cgo to use a different command via the CC environment option.

See https://pkg.go.dev/cmd/go#hdr-Environment_variables for a list of environment variables supported by the go command.

For asking questions, please see https://golang.org/wiki/Questions.

Sorry, I didn't give enough information.
There is no CGO in my Go program. It is pure Go.

Futhermore, if I disable -trimpath into cmd line, then the compilation works without gcc.

I think, this issue is related with #37158, isn't it?

More info here from Ian Lance Taylor: https://groups.google.com/g/golang-nuts/c/dsqLZi2mEog/m/3mcMSda-BAAJ

I see, thanks for more context.

It seems like we can close this issue as a duplicate of #37158, do you agree?

Note that proposal #47257 has been accepted by now, so that will affect this situation when it is resolved.
