Scripts for building Erlang/OTP

I have Erlang/OTP cloned into ~/local/otp and I have my PATH setup with ~/local/otp-install/bin at the front, so I can quickly test out full installs locally.

You can change the INTERESTING_TARGETS variable to point to whatever other flavors you're interested in building.

Usage

You may need to set ERL_TOP to pwd:

cd ~/local/otp
export ERL_TOP="$(pwd)"

First, build it using the "slow" script:

cd ~/local/otp
# this will run configure, boot, and release
./build-otp-slow.sh

After making changes to ERTS, stdlib, etc, you can quickly rebuild with the "fast" script (if you change configure or any of the atom.tab related codegen files, you will need to use the "slow" script again):

cd ~/local/otp
# this will only run the individual emulator builds
./build-otp-fast.sh

Finally: you can install it and use rebar3 from the installation path.

cd ~/local/otp
# this will install into ~/local/otp-install
./build-otp-install.sh

build-otp-fast.sh

#!/usr/bin/env bash

SCRIPT_DIR="$( cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )"
cd "${SCRIPT_DIR}"

export ERL_TOP="${SCRIPT_DIR}"

set -x
set -eo pipefail

make V=1 -j

INTERESTING_TARGETS=(debug)
for TYPE in ${INTERESTING_TARGETS[@]}
do
    make V=1 -C "${ERL_TOP}/erts/emulator" -j "$TYPE"
done

exit 0

build-otp-install.sh

#!/usr/bin/env bash

SCRIPT_DIR="$( cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )"
INSTALL_DIR="${SCRIPT_DIR}/../otp-install"

set -x
set -eo pipefail

rm -rf "${INSTALL_DIR}"
EXTRA_PREFIX="${INSTALL_DIR}" V=1 make install
install -vm 0755 -t ${INSTALL_DIR}/usr/local/lib/erlang/erts-*/bin ${SCRIPT_DIR}/bin/x86_64-pc-linux-gnu/beam* ${SCRIPT_DIR}/bin/x86_64-pc-linux-gnu/erl_child_setup*
cd "${INSTALL_DIR}/usr/local/bin"
wget "https://s3.amazonaws.com/rebar3/rebar3"
chmod +x rebar3

exit 0
