Build Reicast emulator on Ubuntu/Debian

build-reicast.sh

# NOTE: These instructions are old and may be out of date. A better alternative to compiling Reicast manually may be to use RetroArch with the Flycast core (https://www.retroarch.com/)

# Install prerequisites
sudo apt-get -y install build-essential libasound2 libasound2-dev libegl1-mesa-dev libgl1-mesa-dev libgles2-mesa-dev mesa-common-dev
# Build Reicast
git clone https://github.com/reicast/reicast-emulator.git
cd reicast-emulator/shell/linux
make

# Run Reicast
mkdir -p ~/.local/share/reicast/data/
cp ../android/assets/buttons.png ~/.local/share/reicast/data/
cp /path/to/bios/dc_boot.bin ~/.local/share/reicast/data/
cp /path/to/bios/dc_flash.bin ~/.local/share/reicast/data/
./reicast.elf

# To open a ROM
./reicast.elf /path/to/rom.cdi

# Key bindings

# Start: Enter

Failed to compile on Ubuntu 16.04, I get:

I believe that should be fixed:

skmp/reicast-emulator#914

bmaupin is correct. This gist now works fine with Ubuntu 16.04.1.

Is good a debian package that install with:
sudo apt-get install reicast

Make this dream possible, i compile reicast in debian, but buttons and joystick not work.

@usernatilds I have no affiliation with the Reicast project. It might be best to submit any feature requests here: https://github.com/reicast/reicast-emulator

Thanks for the script - having just build the emulator on Arch from AUR with yay- this is exactly what I was looking for on my Ubuntu-based system. I made some tweaks to get libudev-dev dependency and the repo seems to check out by default on the 'alpha' branch which is missing the necessary sub dir, so i simply checkout the 'master' branch before continuing to make.

Thanks, some directories appear to have changed names and locations, but still easy to compile

@davidrc2009 I haven't used this in years but these days if I wanted to use Reicast in Ubuntu I'd probably just use the precompiled flycast core from RetroArch. Maybe I'll make a note indicating as much.

They are only 2 different lines.

Change
cd reicast-emulator/shell/linux
to
cd reicast-emulator/reicast/linux
and
cp ../android/assets/buttons.png ~/.local/share/reicast/data/
to
cp ../android-studio/reicast/src/main/assets/buttons.png ~/.local/share/reicast/data/

Thanks again,
compiling was the only way for me, because installing reicast via snap didn't work.
Cheers.
