A source reconstruction of cod4map.exe, the BSP compiler from the Call of Duty 4 mod tools, recovered from the shipped 2007 binary.
- Visual Studio 2019 or later with the x86 (32-bit) C++ toolset installed (Desktop development with C++ → "MSVC ... C++ x64/x86 build tools")
- CMake 3.21 or later
cmake -B build -A Win32
cmake --build build --config Release
The executable is written to bin\cod4map.exe.
cod4map -platform pc -loadFrom map_source\<mapname>.map raw\maps\mp\<mapname>
Run it from the Call of Duty 4 mod tools directory.
The build uses /arch:IA32 /fp:precise on purpose: the original is an x87
build, and SSE2 code generation changes floating-point results and therefore
the output bytes.
