What were you trying to do (and why)?

I am trying to pack go application, but install with build from source fails.

HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source --verbose --debug p9ufs

Here is the formula.

class P9ufs < Formula

  def install
    system "go", "build", *std_go_args(ldflags: "-s -w"), "./cmd/p9ufs"
  end

  test do
    system "false"
  end
end

What happened (include all command output)?

Choose an action:

This happens with all go packages.

What did you expect to happen?

$ go build -trimpath -o=/tmp/xxx -ldflags="-s -w" ./cmd/p9ufs
$ echo $?
0

This actually happens if I just cd into unpacked source and build it manually. Without Homebrew shell.

Step-by-step reproduction instructions (by running brew commands)

1. `brew edit p9ufs`
2. copy formula from above
3. run install build

HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source --verbose --debug p9ufs

[Bo98]

What's the precise package version of glibc you have installed? I see there was a change in 2.40-23.fc21 (https://src.fedoraproject.org/rpms/glibc/c/09bd51c1753d0bb4bcb2471f478b068f40c29d01?branch=f41) that might have fixed it if you have 2.40-22.fc21 which broke it.

Also worth trying to add any debug/verbose flags you can find to see which gcc go is using under the hood - is it using the system one or the Homebrew one?

[abitrolly]

@Bo98 thanks for the hint! I run dnf update, rebooted and the error is gone. Looks like I've got the newer version that fixes it.
