Current State

Server

The server version can successfully be built. There are few unimplemented stuff from the game library :

Actor
Vehicle

Client

There is currently no client build because the client code is currently unusable. Here is what's missing or unimplemented :

rendering (mostly advanced)
sound (must be reworked)
UI

The client game module (cgame) is partially implemented, and is compatible with the original MOH:AA module.

Running

Backup the existing gamex86.dll (rename it to gamex86.bak).

a) extract archive to your MOHAA installation directory.

-or-

b) Copy all pak*.pk3 files and the sound/ directory from your MOHAA/main directory into openmohaa's 'main' directory.

If you have problems running the game :

You may need to install Microsoft Visual C++ 2015/2017/2019/2022 Redistributable from

https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170

You can now start a local OpenMOHAA server or play on a server.

Compiling

These are the tools required for all platforms :

CMake >= 3.5
Flex and Bison (currently not used)
A C++11 compiler is required.

The installation directory can be set to MOHAA directory.

Linux

These are the tools required on Unix :

Clang >= 3.3 or GCC >= 4.8.1

clang-3.5 and gcc-4.8.5 should work (tested on Ubuntu 16.04).

1 line install command with latest clang version : sudo apt-get install -y ninja-build cmake make clang-15 lld-15 flex bison

Windows

Visual Studio (2019 or 2022) is generally preferred.
