Building Erlang/OTP

9 Jan 2023 18:06 erlang

There’s more comprehensive information in various files in the HOWTO directory, but ain’t nobody got time for that. This works for me.

Building it

export LANG=C
export ERL_TOP="$(pwd)"
./otp_build configure
make -j$(nproc)

Using it

You can sometimes get away with using it directly:

export PATH="$ERL_TOP/bin:$PATH"
erl

Installing it

But, more often, you’ll need to install it:

export RELEASE_ROOT="$HOME/OTP"
cd "$ERL_TOP"
make release

cd "$RELEASE_ROOT"
./Install -minimal "$RELEASE_ROOT"

…and you can use it from there:

export PATH="$RELEASE_ROOT/bin:$PATH"
erl

It will display something like the following:

Erlang/OTP 27 [DEVELOPMENT] [erts-14.0.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]
