build windows

The recommended way (i.e. what its developer does) to build Crispy Doom on Windows is to use the MinGW-w64 compiler in an MSYS2 environment. Follow these steps for compiling 32-bit binaries with GCC (some steps may differ for other build targets, e.g. you'll have to replace all instances of w32 with w64 and i686 with x86_64 in steps 2, 4 and 5 in case you want to do a 64-bit GCC build):

1. Download and install MSYS2.
2. Open the MSYS2 MINGW32 Shell (mingw32.exe) and update the package list:

pacman -Sy
pacman -Suu
pacman -Scc

3. Install some pre-requisites for the build system:

pacman -S base-devel git zip

4. Install the 32-bit compiler toolchain:

pacman -S mingw-w64-i686-autotools mingw-w64-i686-toolchain

Certain compilers may be omitted by adding e.g. --ignore=mingw-w64-i686-gcc-ada,mingw-w64-i686-gcc-fortran,mingw-w64-i686-gcc-libgfortran,mingw-w64-i686-gcc-objc --needed to the command line.

5. Install all mandatory and optional build dependencies:

pacman -S mingw-w64-i686-SDL2 mingw-w64-i686-SDL2_mixer mingw-w64-i686-SDL2_net 
pacman -S mingw-w64-i686-libpng mingw-w64-i686-libsamplerate mingw-w64-i686-python-pillow

Additionally, the pandoc package may get installed to convert some documentation into HTML format, though this is strictly optional.

6. Next, clone the Crispy Doom source code repository from the GitHub project page:

git clone https://github.com/fabiangreffrath/crispy-doom.git
cd crispy-doom

If this doesn't work for some odd reason, try to replace the https protocol with plain http.

7. Bootstrap, configure and compile the sources (this may take some time). The resulting binaries will be in the src/ directory:

autoreconf -fiv
./configure
make

If you are feeling adventurous, you may pass the --enable-truecolor parameter to the ./configure call to build the experimental truecolor renderer (Doom only).

8. To keep your sources and binaries updated, run the following in the source directory:

git pull
make

Usually, Crispy is built with debugging symbols. To strip some bloat off the binaries, call this:

strip src/*.exe
