Building Doodle

Makefile commands for Linux:

• make setup: install Go dependencies and set up the build environment
• make build: build the Doodle and Doodad binaries to the bin/ folder.
• make run: run a local dev build of Doodle in debug mode
• make guitest: run a local dev build in the GUITest scene
• make test: run the test suite
• make dist: produce a zipped release tarball and zip file for your current environment and output into the dist/ folder.
• make docker: run all the Dockerfiles from the docker/ folder to produce dist builds for Debian, Fedora and Ubuntu. You may also run these builds individually:
  • make docker.ubuntu
  • make docker.debian
  • make docker.fedora
• make clean: clean all build artifacts

Linux

Dependencies are Go, SDL2 and SDL2_ttf:

# Fedora
sudo dnf -y install golang SDL2-devel SDL2_ttf-devel

# Ubuntu and Debian
sudo apt -y install golang libsdl2-dev libsdl2-ttf-dev

Windows Cross-Compile from Linux

Install the Mingw C compiler:

# Fedora
sudo dnf -y install mingw64-gcc  # for 64-bit
sudo dnf -y install mingw32-gcc  # for 32-bit

# Arch Linux
pacman -S mingw-w64

Download the SDL2 Mingw development libraries here and SDL2_TTF from here.

Extract each and copy their library folder into the mingw path.

# e.g. /usr/x86_64-w64-mingw32 is usually the correct path, verify on e.g.
# Fedora with `rpm -ql mingw64-filesystem`
tar -xzvf SDL2_ttf-devel-2.0.15-mingw.tar.gz
cd SDL_ttf-2.0.15
sudo cp -r x86_64-w64-mingw32 /usr

Make and set permissions for Go to download the standard library for Windows:

mkdir /usr/lib/golang/pkg/windows_amd64
chown your_username /usr/lib/golang/pkg/windows_amd64

And run make mingw to build the Windows binary.

Windows DLLs

For the .exe to run it will need SDL2.dll and such.

# SDL2.dll and SDL2_ttf.dll
cp /usr/x86_64-w64-mingw32/bin/SDL*.dll bin/

SDL2_ttf requires libfreetype, you can get its DLL here: https://github.com/ubawurinna/freetype-windows-binaries
