Building for Windows on Linux

This is the main build procedure for Windows version cross-compiled on Linux.

For building on Windows, see this page.

Installing Go compiler

Fastest way

sudo snap install --classic go

Longer way

See official docs.

Installing C cross-compiler

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install gcc-multilib gcc-mingw-w64

Installing other dependencies

SDL for MinGW

cd /tmp
curl -so ./sdl2.tar.gz https://www.libsdl.org/release/SDL2-devel-2.0.14-mingw.tar.gz
tar -xzf ./sdl2.tar.gz
sudo mv ./SDL2-2.0.14/i686-w64-mingw32/include/* /usr/i686-w64-mingw32/include/
sudo mv ./SDL2-2.0.14/i686-w64-mingw32/lib/* /usr/i686-w64-mingw32/lib/

OpenAL

cd /tmp
curl -so openal.zip https://openal-soft.org/openal-binaries/openal-soft-1.21.1-bin.zip
unzip ./openal.zip
sudo mv ./openal-soft-1.21.1-bin/include/* /usr/i686-w64-mingw32/include/
sudo mv ./openal-soft-1.21.1-bin/libs/Win32/* /usr/i686-w64-mingw32/lib/
sudo ln -s ./libOpenAL32.dll.a /usr/i686-w64-mingw32/lib/libOpenAL.dll.a

Building

make build-client-win

This should produce opennox.exe and opennox-hd.exe binaries.
