# Compiling
|
|
|
|
OpenMoHAA supports any architecture, thanks to the CMake build system and cross-platform code/libraries. While the most common little-Endian architectures (arm, aarch64, x86, x86_64) have been tested and confirmed to work, big-Endian architectures should be supported as well; however, they remain untested.
|
|
|
|
The following tools are required for all platforms:
|
|
- CMake >= 3.5
|
|
- Flex (>= 2.6.4) and Bison (>= 3.5.1)
|
|
- A C++11 compiler
|
|
- OpenAL SDK (can be found [here](https://github.com/kcat/openal-soft))
|
|
|
|
The installation directory can be set to the MOHAA directory.
|
|
|
|
By default, the build will produce both the client and dedicated server versions. The client can be omitted from the build by appending `-DBUILD_NO_CLIENT=1` to the CMake command-line arguments. Using this parameter will result in only the server portion being built.
|
|
|
|
OpenAL can be disabled by appending `-DNO_OPENAL=1` to the CMake command-line arguments. The old SDL-based sound system will be used instead, it lacks some features such as ambient sounds.
|
|
|
|
## Compiling for Linux
|
|
|
|
These are the tools required on Linux :
|
|
- Clang >= 3.3 or GCC >= 4.8.5
|
|
- libsdl2-dev
|
|
- libopenal-dev
|
|
|
|
**clang-3.5** and **gcc-4.8.5** should work (tested on Ubuntu 16.04), but the latest version should be used.
|
|
|
|
Ubuntu 20.04 is the minimum version required to fully compile the project successfully.
|
|
|
|
1 line install command with clang:
|
|
```sh
|
|
sudo apt-get install -y cmake ninja-build clang lld flex bison libsdl2-dev libopenal-dev
|
|
```
|
|
|
|
Example with **CMake** and **ninja-build** installed:
|
|
```sh
|
|
mkdir .cmake && cd .cmake
|
|
cmake -G Ninja ../
|
|
```
|
|
|
|
Other compilers can be specified by appending `-DCMAKE_C_COMPILER=/path/to/compiler -DCMAKE_CXX_COMPILER=path/to/compiler` to the CMake command-line.
|
|
|
|
## Compiling for Windows
|
|
|
|
Visual Studio (2019 or 2022) is generally preferred.
|
|
|
|
Flex and Bison can be downloaded from here: https://github.com/lexxmark/winflexbison/releases/tag/v2.5.25
|
|
OpenAL can be downloaded from here: https://github.com/kcat/openal-soft/releases/tag/1.23.1 rename `soft_oal.dll` to `OpenAL64.dll` on 64-bit and `OpenAL32.dll` on 32-bit
|
|
|
|
Append `-DFLEX_EXECUTABLE=...\win_flex.exe -DBISON_EXECUTABLE=...\win_bison.exe -DOPENAL_INCLUDE_DIR="path/to/oal/include" -DOPENAL_LIBRARY="path/to/oal"` to the CMake command-line to use the package from the link above.
