Build a portable bottle

The bottles for binutils, patchelf and zlib are special. Because they are installed before glibc, they must be able to run on host systems using an older version of glibc. Linuxbrew supports host systems with glibc 2.5 and newer. We use CentOS 5 with glibc 2.5 to build portable bottles.

Follow these instructions to install CentOS 5 on Docker up until "Install dependencies of Linuxbrew". Stop before brew install gcc git ruby.

Build a portable bottle for binutils.

export HOMEBREW_NO_AUTO_UPDATE=1
brew install --build-bottle binutils
brew install file-formula
brew bottle --json binutils

Add the sha256 of the bottle to the binutils formula.

git config --global user.name LinuxbrewTestBot
git config --global user.email testbot@linuxbrew.sh
brew bottle --merge --write --keep-old binutils-*.x86_64_linux.bottle.json

Test the bottle.

brew remove --ignore-dependencies binutils
brew install ./binutils-*.x86_64_linux.bottle.tar.gz
brew install ruby # Fix Error: cannot load such file -- test/unit/assertions
brew test binutils

Upload the bottle to Bintray using brew test-bot.

export BINTRAY_USER=linuxbrewtestbot
export BINTRAY_KEY=...
export CIRCLE_PR_NUMBER=...
brew test-bot --ci-upload --keep-old

Or upload the bottle to Bintray using curl.

curl -u$BINTRAY_USER:$BINTRAY_KEY -T binutils-$version.x86_64_linux.bottle.tar.gz "https://api.bintray.com/content/linuxbrew/bottles/binutils/$version/binutils-$version.x86_64_linux.bottle.tar.gz?publish=1"

Commit and push the formula to GitHub.

git commit --amend binutils.rb -m"binutils: update $version bottle for Linuxbrew.

This portable bottle was built using glibc 2.5 on CentOS 5."
