PenUltima Online (POL) is a MMO server, compatible with most Ultima Online clients. POL is customizable via configuration files and has its own scripting language (eScript).

If you find bugs, please create an issue with the dump, relevant log lines and your best guess on how to reproduce the bug.
Current version: POL 100 (in development).
Always check the core-changes.txt file for breaking changes when using the development version. We'll strive to keep the development version stable. If you are looking for POL099, check the branch "POL099". From now on, POL099 will only receive bug-fixes.
You can send us pull requests at anytime. We expect you to be the author of the contributed code or that it's in a compatible license.
We always need updates or better descriptions in the docs, so feel free to send pull requests for changing them. You can find some of them in docs/docs.polserver.com/pol100.
The best way to get used to the code is to search for eScript functions in the cpp files. For example, "SystemFindObjectBySerial" or "ApplyDamage". This way you can see how eScript interfaces with the core and how to add/modify modules and functions.
You need atleast cmake version 3.0.
Open the cmake gui select the CMakeLists.txt in the root folder and select your installed Visual Studio version e.g. Visual Studio 15 2015 Win64. As build directory it is recommended to use bin-build. Now simply press configure+generate and you can directly open the solution file in your IDE. After building the binaries are located in the bin folder.
Minimum compiler version: Visual Studio 2015
Warning: We can not easily debug dumps from self-compiled cores. Make sure you save the .pdb and .exe!
Make sure you have the required libraries installed: zlib and the mysql client (if SQL supported is desired).
Then run the following commands (you need at least CMake 3.0):
cd bin-build./build_linux.sh
Minimum compiler version: GCC 4.9 or LLVM/Clang 3.5.
For compiling with GCC 4.7 and 4.8, please see the Advanced Compiling section on how to enable USE_BOOST_REGEX=1
The command will generate binaries and dynamicaly linked libraries in the bin/ folder. You need them all for your binaries to work. Debug symbols are included by default.
To generate a compressed distributable archive (without debug symbols), then use ./build_linux_release.sh.
The following instructions are only for advanced users. If you only want to compile the core, please follow the steps above.
This software uses a CMake-based build system. CMake is a build system generator: on Linux, it will take care of generating a Makefile. If you are familiar with linux source tarballs, just think of cmake as a modern replacement for the good old ./configure script.
First of all, run cmake one first time and let it do some autodetection:
cd bin-build
cmake ..
A file called CMakeCache.txt has now been created: inside this file, you will find all the settings that will be used for your build. You have many options to edit this file:
- by hand, with your favorite text editor (read the comments in the file header for a quick syntax briefing)
- from a terminal GUI, like
ccmake(sudo apt-get install cmake-curses-guito install it on Debian-based systems): just launch the gui by typingccmake .and follow the interface - from a X window GUI, like
cmake-gui(sudo apt-get install cmake-qt-guito install it on Debian-based systems): just launch the gui by typingcmake-gui .and follow the interface
Here is a non-complete description of the most useful options:
FORCE_ARCH_BITS='<bits>'replace <bits> with 32 to force a 32 bit build, 64, to force a 64 bit build. The default settings use autodetection.BUILD='<type>'replace <type> with one of the following:Default: runs the default build using default settingsDebug: makes a debug build (adds '-O2', '-g', '--ggdb')Valgrind: makes a special debug build to be used in Valgrind that will run very slowly (like Debug, but uses '-O0' instead of '-O2')
USE_BOOST_REGEX=<1|0>if set to 1, uses boost instead of std regex to work around a GCC bug in versions prior to 4.9
You can also set an option directly with the '-D' cmake flag, by example:
cmake -Wno-dev -DFORCE_ARCH_BITS=32 -DBUILD=Debug
Keep in mind that even when set this way, the option will be saved in the CMakeCache.txt configuraton file and remembered for future builds.
You can now use the classic make command to compile the POL. You can type:
makeormake allto do the buildmake cleanto delete all the intermediate build files
You will find the compiled files inside the bin/ folder.
