Building RetroArch-Web

Instructions have only been confirmed working for Debian and Fedora.

Dependencies

• Build Essential
• PkgConf
• BinUtils
• Python
• Git
• Emscripten

Debian:

sudo apt install -y         \
    binutils-mips-linux-gnu \
    build-essential         \
    pkgconf                 \
    python3                 \
    git 

Fedora:

sudo dnf groupinstall "Development Tools" "Development Libraries"

To install emscripten, run this command. Note this will only temporarily add emscripten to your path. Follow the on screen directions when it finishes to make this permanent.

cd; && \
git clone https://github.com/emscripten-core/emsdk.git .emsdk && \
cd .emsdk && ./emsdk install latest && ./emsdk activate latest && source ./emsdk_env.sh

It is highly recommended to use this script to compile the cores. It will compile every core and package them for you.
