Compiling Chocolate Doom under Cygwin

chocolate-doom-under-cygwin.adoc

Intalling cygwin

Select the packages:

• autoconf

• automake

• git

• mingw64-i686-SDL2

• mingw64-i686-SDL2_mixer

• mingw64-i686-SDL2_net

• mingw64-i686-gcc-core

• mingw64-i686-libpng

• mingw64-i686-libsamplerate

• pkg-config

• python

• zip

python3 should work equally as well as python

zip isn’t required, but if you want to give the build to others…​

Cloning chocolate-doom

As usual.

git clone https://github.com/chocolate-doom/chocolate-doom

Generating ./configure

Either run autoconf -fi or ./autogen.sh. The latter will fail on a fresh Cygwin install, after it runs ./configure, with only the packages I specified, there’s no Cygwin compiler installed. This is fine.

Building

Running ./configure --host i686-w64-mingw32 should succeed at this point.

After doing that, just run make (possibly with -j for a parallelized build)

Running/distributing

At present, doing make -C pkg/win32 doesn’t work, cp-with-libs isn’t passed in parameters that lets it find the mingw64 DLLs Cygwin installs. We can workaround:

1. cd pkg/win32

2. mkdir doom

3. ./cp-with-libs --dll_path=/usr/i686-w64-mingw32/sys-root/mingw/bin ../../src/chocolate-doom-setup.exe doom

4. ./cp-with-libs --dll_path=/usr/i686-w64-mingw32/sys-root/mingw/bin ../../src/chocolate-doom.exe doom

5. (Optional) zip -j chocolate-doom-sdl2.zip doom

Conclusion

Failed to have a working build. Trying to run the EXEs results in a out of memory error. Don’t know why. These instructions might still be helpful for others.
