[chauncey-garrett]

Please always follow these steps:

• [x] Confirmed this is a problem with brew installing one, specific formula and not every time you run brew? If it's a general brew problem please file this issue at https://github.com/Linuxbrew/brew/issues/new.
• [x] If you have a macOS system and can replicate the problem on macOS with Homebrew, please report the issue to Homebrew/core and follow their issue template from your macOS system. If you are unsure, please report the issue to Linuxbrew.
• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed all issues and retried your prior step?
• [x] Ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?
• [x] If brew gist-logs didn't work: ran brew config and brew doctor and included their output with your issue?

brew install pkg-config fails.

[sjackman]

Consider installing Linuxbrew in /home/linuxbrew/.linuxbrew/ if possible so that you can use precompiled binary packages (known as bottles) for non-relocatable formula like pkg-config.
Another possible workaround for you is brew install --force-bottle pkg-config, but no promises.

The precompiled binary bottles of non-relocatable bottles can only be used if you install in /home/linuxbrew/.linuxbrew, otherwise they have to be built from source. See the documentation below, but wherever it reads /usr/local, which is for macOS, read instead /home/linuxbrew/.linuxbrew.

I did try brew reinstall gcc but it didn't fix things.

I may also start over with /home/linuxbrew as suggested -- that must be new since I started using linuxbrew a good while back -- but I can wait if you'd like to troubleshoot why it's not currently working as expected.

[sjackman]

A new installation of Linuxbrew using the installer script at http://linuxbrew.sh/#install-linuxbrew will use /home/linuxbrew/.linuxbrew by default if you have sudo access. Let's see if that works for you.

[chauncey-garrett]

Installed linuxbrew as suggested and was able to install most things but still having an issue with gcc.

Here, installation of nodenv failed from similar gcc failures:

https://gist.github.com/anonymous/da62e40db322b89f9366910b74ca5a18

But you can see it's available in my PATH:

It also fails when installing hadolint, rust, and the_silver_searcher.

hadolint didn't provide any logs:

rust:

the_silver_searcher:

https://gist.github.com/anonymous/3064a9c88d69480c62ac6e5ee9c777d0

[sjackman]

I've opened PRs #3868 and #3869 to build bottles for hadolint and the_silver_searcher.
The last build of rust on CircleCI timed out, but I'm giving it another shot at PR #3870.

[sjackman]

Please report the output of…

brew sh <<<'echo $PATH; which -a gcc-7'

[sjackman]

hadolint and the_silver_searcher are bottled now. I didn't unfortunately have any luck with rust.

[chauncey-garrett]

[sjackman]

That looks as expected.

[chauncey-garrett]

hadolint and the_silver_searcher work as expected. 👍

[sjackman]

I've bottled rust for Linuxbrew. I had to build it in Docker on my local machine, because it exceeded CircleCI's memory limit of 4 GB.

[chauncey-garrett]

+1 for docker! I downloaded rust but got a warning I've never seen before:

Other than that, rust (and cargo) appear to be working.

[chauncey-garrett]

From the original items I was trying to install, I think that leaves nodenv which still has the gcc-7 error.

[sjackman]

As a workaround, the following should work.

brew install nodenv --without-bash-extension

[chauncey-garrett]

Works! Thank you for the help!
