MSYS2 can be used as freeciv build/development environment on Windows.
First time setup[]
- Download latest msys2 environment from http://files.freeciv.org/packages/windows/msys2/
- Extract the environment from the package to a suitable location. 7-zip from http://www.7-zip.org can be used for extracting.
- Start the msys2 shell from mingw32.exe (to produce win32 builds) or mingw64.exe (to produce win64 builds) at environment root. If you selected mingw32.exe, ${ARCH} in following examples is mingw32. If you selected mingw64.exe, ${ARCH} is mingw64.
- Setup git directories. In the shell:
> mkdir freeciv > cd freeciv # Create root dirs for branch-specific directory hierarchies > mkdir master > mkdir S3_1 > mkdir S3_0 > # Clone freeciv repository under master/src > cd master > git clone https://github.com/freeciv/freeciv.git src # Create worktrees for all the other branches > cd src > git worktree add ../S3_1/src S3_1 > git worktree add ../S3_0/src S3_0
- Create build directories.
# Do following for each of the branches (master, S3_1, S3_0)
# This example if for S3_0
> cd ~/freeciv/S3_0/src
> ./autogen.sh --no-configure-run
> cd ..
> mkdir builds
> cd builds
# Create configurations you want. This example creates
# simple gtk3.22-, Qt-, and sdl2-client configurations
> mkdir gtk3.22
> cd gtk3.22
> ../../src/configure --enable-debug --without-readline --enable-client=gtk3.22
> cd ..
> mkdir qt
> cd qt
> ../../src/configure --enable-debug --without-readline --enable-client=qt --with-qt5-includes=/${ARCH}/include --with-qt5-libs=/${ARCH}/lib
> cd ..
> mkdir sdl2
> cd sdl2
> ../../src/configure --enable-debug --without-readline --enable-client=sdl2
Building and running freeciv[]
- Go to directory of the configuration you want to build. For example S3_0 gtk3.22-client configuration
> cd ~/freeciv/S3_0/builds/gtk3.22
- Run make to build freeciv
> make
- Run produced freeciv.
> ./fcgui
Updating sources to latest ones[]
- Go to source directory of the branch you want to update. For example S2_6:
> cd ~/freeciv/S2_6/src
- Pull the changes since your last update
> git pull
You are now ready to rebuild configurations of that branch from the updated sources.
Updating msys2 environment[]
If you want to keep your msys2 environment updated against upstream changes, you can do that with
> pacman -Syu
Notice however that such updates should not be made for environments used to build official freeciv installers, as the installers should be created in well-specified environments, not necessarily up-to-date (what ever that means at a given moment) environments.
Improving msys2 environment performance[]
Msys2 environment can be very slow to use. Msys2org tweeted: "Adding the MSYS2 directory to the defender exclusion list helps a lot."
