Installing Erlang/OTP

HyperBEAM is built on Erlang/OTP, so you'll need to have Erlang installed on your system.

Ubuntu 22.04Mac OS

Building Erlang from Source

For the best compatibility, we recommend building Erlang from source:

git clone https://github.com/erlang/otp.git && \
    cd otp && git checkout maint-27 && \
    ./configure --without-wx --without-debugger --without-observer --without-et && \
    make -j$(nproc) && \
    sudo make install && \
    cd .. && rm -rf otp

This will:

1. Clone the Erlang/OTP repository
2. Checkout the maintenance branch for version 27
3. Configure the build to exclude GUI components (reducing dependencies)
4. Build Erlang using all available CPU cores
5. Install Erlang system-wide
6. Clean up the source directory

Verify Installation

You can verify your Erlang installation with:

erl -eval 'erlang:display(erlang:system_info(otp_release)), halt().'

This should output 27, indicating the OTP release version.
