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.

Install a recent version of file that supports --print0.

HOMEBREW_BUILD_FROM_SOURCE=1 HOMEBREW_NO_AUTO_UPDATE=1 brew install file-formula

Install build dependencies of binutils.

sudo yum install -y bison flex makeinfo

Build a portable bottle for binutils.

export HOMEBREW_NO_AUTO_UPDATE=1
brew install --build-bottle binutils
brew bottle --json binutils
brew test binutils

Upload the bottle to Bintray using curl.

export BINTRAY_USER=linuxbrewtestbot BINTRAY_KEY=...
version=$(brew list --versions binutils | sed 's/.* //')
curl -u$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" >curl.out

Add the sha256 of the bottle to the binutils formula manually.

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

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

Optional steps

Add the sha256 of the bottle to the binutils formula.

brew install git
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
