Compile
You can get Omni-bot C++ source code from GitHub: https://github.com/jswigart/omni-bot
Latest Omni-bot version for Enemy Territory and Return to Castle Wolfenstein is in the stable branch !!!
Use the Download ZIP button or install Git and then clone the repository.
You also need submodule GameMonkey: https://github.com/jswigart/gmscriptex
Omni-bot depends on the Boost libraries which can be downloaded from https://sourceforge.net/projects/boost/
Linux
Compile Boost
If your Linux distribution contains boost packages, you can just install the packages and skip this step.
Run shell as root. Change current directory to boost.
./bootstrap.sh --with-libraries=date_time,filesystem,regex,system ./bjam address-model=32 link=static install
Header files will be copied into /usr/local/include/boost. Libraries will be copied into /usr/local/lib
It's possible to install boost to another folder which does not require root privileges. See boost documentation.
Compile Omni-bot
If you want to compile Omni-bot for other games than Enemy Territory, open the file Omnibot\Jamfile in a text editor and uncomment build-project commands (they are at the end of Jamfile).
Open script Omnibot\linux\buildbot.sh in a text editor and change paths. The BOOST_SUFFIX variable should be empty in current Boost version. Then run the script.
If you are lucky and compilation is successful, you will have file omnibot_et.so or omnibot_rtcw.so somewhere in Omnibot\build folder.
Compile Mods
Run script buildet.sh or buildrtcw.sh.
Files cgame.mp.i386.so and ui.mp.i386.so must be compressed into archive omnibot_et.pk3 or omnibot_rtcw.pk3.
64-bit
If you use 64-bit ET:Legacy and legacy mod, you must compile 64-bit Omni-bot.
Add parameters address-model=64 cflags=-fPIC when you compile Boost.
Add parameter address-model=64 to bjam command when you compile Omni-bot.
Windows
Project files are for Microsoft Visual Studio 2017 or newer. You can use free Community edition.
Compile Boost
Start "x86 Native Tools Command Prompt for VS" from the Start menu. Change current directory to boost root.
bootstrap.bat .\bjam --with-date_time --with-filesystem --with-regex --with-system link=static runtime-link=static variant=release
Change variant parameter to debug if you want to compile Omni-bot with debugging info.
Change runtime-link parameter to shared if you want to use Code Generation / Runtime Library - Multi-threaded DLL (/MD)
Compile Omni-bot
Open file Omnibot\projects\msvc12\PropertySheets\Paths.props in a text editor and change BOOST path.
Open solution Omnibot\projects\msvc12\Omni-bot2013.sln
The solution contains projects for all supported and unsupported games. You probably only need to compile projects Common, gm_ex and MOD_ET or MOD_RTCW.
Select Release or Debug configuration on toolbar and compile. There is a Post-Build Event defined to copy output file to installation folder. You can modify it if you want another folder. If you are lucky and compilation is successful, you will have file omnibot_et.dll or omnibot_rtcw.dll.
Compile Mods
Enemy Territory mod solution: GameInterfaces\ET\src\wolf_2013.sln
Return to Castle Wolfenstein solution: GameInterfaces\RTCW\src\RTCW2010.sln
There are 3 projects in the solution: cgame, game, ui. Projects cgame and ui have Post-Build Event defined to compress cgame_mp_x86.dll and ui_mp_x86.dll into omnibot_et.pk3 or omnibot_rtcw.pk3.
