Pence's Quake Source Hacks

I don't even want to call this a game yet; this is just a collection of hacks because I think it's fun to hack on the Quake source code, and have for, I dunno, more than a decade now.

Building

You'll need:

• A copy of Quake for the assets (obviously)
• SDL2 http://www.libsdl.org/
• GLEW http://glew.sourceforge.net/
• glm https://glm.g-truc.net/
• PhysicsFS https://icculus.org/physfs/
• ENet http://enet.bespin.org/index.html

Libraries already bundled here:

• SoLoud (2020.02.07) http://sol.gfxile.net/soloud/index.html

To build, generate Makefiles for your platform with cmake.

Building with Static Analysis

To run Clang's static analysis on the code, call CMake as follows:

mkdir ../tmp
cd ../tmp
scan-build cmake -DCMAKE_CXX_COMPILER=/usr/lib/clang/c++-analyzer -DCMAKE_C_COMPILER=/usr/lib/clang/ccc-analyzer ../quake
scan-build make clean all

To run cppcheck, call:

cppcheck --project=build/compile_commands.json 2> out

Tags

I've got a few tags in this repository for various points in the development history that I might want to roll back to at some point in the future. They are:

• v0.9: Port math library to glm.
• v0.8: Move lots of string and array handling to std::string and std::vector.
• v0.7: Lots of C++ cleaning, just before work started on memory management.
• v0.6: Ported the video to SDL, the network to ENet, and the sound to SoLoud; compiling as C++.
• v0.5: Ported the QuakeC into C, though still rather buggy and untested.
• v0.4: Cleaned up QuakeC to a more C-like dialect.
• v0.3: QuakeC added and compiling.
• v0.2: Filesystem ported to PhysicsFS; QuakeC string handling fixed.
• v0.1: Initial clean source code, building under Linux, loads without crashing, a bit of cleanup of unused platform-specific code. Code reformatted to Google style. Few other changes.
