Clang format can be used to automatically format code submissions. Go here for more information on Clang format:

Travis Integration

Mudlet is hosted on Github and uses Travis for continuous integration by building on a Ubuntu 12.04 (Precise Pangolin) LTS Linux and a MacOs Mavericks (10.9) platforms. This means that every push to the Git repository is test compiled on both Ubuntu and Mac OSX but not Microsoft Windows (yet).

Travis integration is defined in a .travis.yml file and in our case, it references shell scripts in the CI directory, which handle things like installing dependencies and building mudlet.

Note Note: Travis builds do not currently package mudlet, so not everything is automated.


Note Note: Mudlet uses Qt 5.x now, at one stage it was Qt5.2 or later but I think I have fixed that. {Note: so far it has proven possible to compile using a late Qt4.x but some code does have to be changed this is my backport of the 3.0.0 release post-delta preview code but I expect it is not likely to be merged - and it has not been proven to be fully functional, only build-able - your mileage may vary!} slysven

Note Note: Mudlet uses C++11 features now. Please use the latest versions of GCC (4.9.1) and Clang (3.5), if possible.

Compiling on Ubuntu 12.04

1. Install Git

 sudo apt-get install git

2. Get Mudlet source

 git clone mudlet

3. Go to the parent of the mudlet "src" folder and create (if necessary) a build subdirectory

(This is so that we can build out of source which keeps the source code clean!}

 cd mudlet
 mkdir build

4. Setup your environment


5 Move to the build location

 cd build

6. Run the following commands, depending on which build system you want to use (qmake IS recommended for Linux and Mac platforms)


 qmake ../src/


 cmake ..


 make -j 2

if you have more than one processor core you can increase the number after -j to one more than the number of cores you would like to devote to building the application to speed things up.

7. Start the application you have just compiled - enjoy


Compiling on OS X

1. Install prerequisites

Install XCode, command line tools for XCode, and HomeBrew.

Once homebrew is installed, do:

 brew doctor
 brew update
 brew install git

2. Get Mudlet source

 git clone mudlet

3. Go to the parent of the mudlet "src" folder and create (if necessary) a build subdirectory (this is so that we can build out of source which keeps the source code clean}

 mkdir build

3. Setup your environment you only need the first three lines if your system cannot find the right Qt libraries or tools, the added directories might be different if you have installed them differently

 export PATH="/usr/local/opt/qt5/bin:$PATH"
 export LDFLAGS=" -L/usr/local/opt/qt5/lib ${LDFLAGS}"
 export CPPFLAGS=" -I/usr/local/opt/qt5/include ${CPPFLAGS}"

4. Go to the mudlet build folder

 cd build

5. Run the following commands, depending on which build system you want to use (qmake IS recommended for Linux and Mac platforms)


 qmake ../src/


 cmake ..


 make -j 2
 make install

if you have more than one processor core you can increase the number after -j to one more than the number of cores you would like to devote to building the application to speed things up.

6. Enjoy

The is now available in Finder for launching.

Compiling on Debian 'Sid'

1. Install required packages from main repo.

$ sudo apt-get install build-essential lua5.1 liblua5.1-0-dev libpcre3-dev libboost-dev zlib1g-dbg zlib1g-dev libyajl2 \
libyajl-dev libyajl2-dbg libphonon-dev libhunspell-dev lua-filesystem zlib-bin libzzip-dev lua-rex-pcre lua-zip \
lua-sql-sqlite3 qt5-default git libquazip-dev

2. Grab latest Mudlet source.

$ cd ~ && mkdir projects && cd projects && git clone

3. Build latest libzip.

$ cd mudlet/src && wget
$ tar -xvzf libzip-0.11.1.tar.gz && cd libzip-0.11.1
$ ./configure && make && sudo make install

Note Note: libzip has since reached the version 1.0 milestone - and it is possible that we will move forward to use later version library calls - this version is, I think the minimum version that is usable with the current Mudlet code which may be an issue for some earlier Debian distributions (7.x, "Wheezy" at least only ships a 0.10.x version). --slysven 19:41, 15 January 2017 (EST)

4. Download and install QT development package.

$ \curl -sS
$ chmod +x qt-opensource* && ./qt-opensource*

5. Fix issues.

$ sudo ln -s /usr/local/lib/libzip/include/zipconf.h /usr/local/include/zipconf.h

6. Build Mudlet.

$ cd ..
$ /home/<username>/Qt5.3.1/5.3/gcc/bin/qmake
$ make

Compiling in ArchLinux

The best way to do this would be to use the PKGBUILD found here. You'll just download the PKGBUILD into a directory, run

sudo pacman -U [name of the generated pkg file]

and you'll be done. For more info on what this does, visit this site.

Compiling in Gentoo

An overlay is available for compiling Mudlet on Gentoo.

Compiling on Windows 10

1.Download & Install the Prerequisites

Run the installer and de-select everything and just select:
 Qt->Qt 5.6->MinGW 4.9.2 (32 bit)
 Qt->Qt 5.6->Source components
In this tutorial, it is installed in C:\Qt\ (so you will have C:\Qt\5.x)
Notepad++: (at the last check it was at version 7.3)
Recommended if you don't have a good source editor installed already (it is release under a GPL License).
extract this to C:\mingw32
Latest msys from:
put the msys folder in C:\mingw32, so you get C:\mingw32\msys

2.Download libraries in MSYS

Open MSYS (click msys.bat in the C:\mingw32\msys folder), where you'll be in a home directory. Copy the lines below and right-click on the terminal to paste them:

mkdir src
cd src
wget --no-check-certificate --output-document hunspell-1.4.1.tar.gz
wget --no-check-certificate
wget --no-check-certificate
wget --no-check-certificate --output-document yajl-2.0.1.tar.gz
wget --no-check-certificate

A folder will get created in C:\mingw32\msys\home\your_name\src with all the files.

Extract all libraries with:

for a in `ls -1 *.tar.gz`; do tar -zxvf $a; done
for a in `ls -1 *.tar.bz2`; do tar xvfj $a; done


wget --no-check-certificate
/c/Program\ Files/7-Zip/7z e boost_1_60_0.tar.gz && /c/Program\ Files/7-Zip/7z x boost_1_60_0.tar
cp -r boost_1_60_0/boost /c/mingw32/include

3.Compiling libraries

Environment Settings

You want control over what compilers are being using so prefix your Path with (in system environmental variables):

C:\Program Files (x86)\CMake\bin

Be sure to restart msys.bat after setting the above to pick up the new values.

MSYS Compilations

All of the following will be completed inside the msys command prompt.

cd into each respective directory:


./configure --prefix=/c/mingw32 && make -j 2 && make install

YAJL: Edit CMakeLists.txt in the base dir of YAJL, and make the following changes to remove all the windows specific compiler settings:

SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} /wd4996 /wd4255 /wd4130 /wd4100 /wd4711") to SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS}")

Then compile:

mkdir build
cd build
cmake -G "MSYS Makefiles" ..
cp yajl-2.0.1/lib/* /c/mingw32/lib/
cp -R yajl-2.0.1/include/* /c/mingw32/include/

Lua: edit the Makefile, change INSTALL_TOP= /usr/local to INSTALL_TOP= /c/mingw32

change TO_LIB= liblua.a to TO_LIB= liblua.a lua51.dll

make mingw
make install


./configure --prefix=/c/mingw32 && make -j 2 && make install


./configure --prefix=/c/mingw32 && make -j 2 && make install


make -f win32/Makefile.gcc
export INCLUDE_PATH=/c/mingw32/include/
export LIBRARY_PATH=/c/mingw32/lib/
export BINARY_PATH=/c/mingw32/bin/
make -f win32/Makefile.gcc install
cp zlib1.dll /c/mingw32/bin
cp libz.dll.a /c/mingw32/lib


./configure --prefix=/c/mingw32 && make -j 2 && make install
cp lib/zipconf.h /c/mingw32/include


powershell -Command "(gc configure) -replace 'uname -msr', 'uname -ms' | Out-File -encoding ASCII configure"
configure --disable-mmap --prefix=c:/mingw32/ && make -j 2 && make install

3.Downloading Mudlet Sources

Getting Mudlet

From within msys:

cd ~/src
git clone
cd Mudlet/src
git checkout release_30 

Building Mudlet from terminal

cd ~/src/Mudlet/src
make -j 2

Building Mudlet from QtCreator

Open (within Mudlet2/src) in Qt Creator

4.Copy Needed DLLs

Copy the following dll's into the release directory:

cd release/
cp /c/Qt/5.6/mingw49_32/bin/icudt54.dll .
cp /c/Qt/5.6/mingw49_32/bin/icuin54.dll .

cp -r /c/Qt/5.6/mingw49_32/plugins/mediaservice .
cp -r /c/Qt/5.6/mingw49_32/plugins/platforms .

5.Setting up Lua libraries

At this point your Lua install will be bare-bones and lacking the Lua libraries Mudlet uses.

cd ~/src
wget --no-check-certificate

Switch to the Windows command line to install luarocks:

cd C:\mingw32\msys\home\%USERNAME%\src\luarocks-2.4.0-win32
install.bat /P C:\LuaRocks /MW

Wait for the installation to finish. Then:

cd \LuaRocks\lua\luarocks
powershell -Command "(gc cfg.lua) -replace 'mingw32-gcc', 'gcc' | Out-File -encoding ASCII cfg.lua"
cd \LuaRocks
luarocks install LuaFileSystem
luarocks install LuaSQL-SQLite3 SQLITE_INCDIR="c:\mingw32\include" SQLITE_LIBDIR="c:\mingw32\lib"
luarocks install lrexlib-pcre PCRE_LIBDIR="c:\mingw32\lib" PCRE_INCDIR="c:\mingw32\include"

Back in the msys command line:

cd ~/src
wget --no-check-certificate
unzip master
cd luazip-master/
gcc -O2 -c -o src/luazip.o -IC:/mingw32/include/ src/luazip.c 
gcc -shared -o zip.dll src/luazip.o -Lc:\mingw32\lib -lzzip -lz c:/mingw32/bin/lua51.dll -lm
cp zip.dll ~/src/Mudlet/src/release
cp -r /c/mingw32/lib/lua/5.1/* ~/src/Mudlet/src/release

You're done! You can now launch mudlet by running mudlet.exe in the release/ folder, or from command line:

cd ~/src/Mudlet/src/release

Outdated compiling instructions

Instructions below need to be updated.

Compiling on Debian 7.1 ("Wheezy")

1. Install GIT. In a terminal window type:

sudo apt-get install git

2. Install needed Debian packages. Only the development [-dev] ones are shown here, as this should also get the associated main packages auto-magically if not already present on the system:

sudo apt-get install "compiler packages & qt-sdk packages"
liblua5.1-0-dev libboost-dev libhunspell-dev libphonon-dev lua-zlib-dev
libzip-dev libyajl-dev lua-rex-pcre lua-zip lua-filesystem lua-sql-sqlite3

N.B. "compiler packages & qt-sdk packages" could probably be "g++", "libstdc++6" and "qmake" to pull in the default GCC C++ compiler and associated libraries and qt Make system; "qt4-dev-tools" to pull in the development Qt libraries; "gdb" if you are planning on doing any debugging and "qtcreator" to provide a nice IDE to do it all in. The last four dependences are not required to compile the code but their absence will show up in error messages from the LUA subsystem as connection is made to a MUD and the session starts up, unlike other dependences only the main files seem to be required (it not being necessary to include the development [-dev] packages.)

3. Build and install non-Debian packages. Which presently is only the C++/Qt Zip library "quazip", download the latest version After unzipping to a new directory of your choice add: "QMAKE_CXXFLAGS += -fpermissive" near the top of the "./qztest/" file to change errors to warnings on assigning some gzFile pointers to void ones in the test suite - this seems to be needed to get the whole thing to compile (though the test suite isn't necessary for compiling Mudlet purposes). After making that change in a terminal window run "qmake" on the quazip project file in the base of the quazip project directory tree to update the subdirectory project files. After building (with "make") in that base directory use "sudo make install" to install the newly constructed files in your system - this puts headers in /include and libraries in /lib of your file-system so some tweaking in the last couple of bits of this section could avoid the need to manually move the library and the three symbolic links from /lib to /usr/local/lib/ and the header files from /includes to /usr/local/includes/.

4. Get the Mudlet source. In a terminal window:

git clone git://

5. Compile the Mudlet source. In that terminal window:


or if you've got qtcreator set up once you've opened the Mudlet project file which is "./src/" relative to wherever you had Git clone the code in the previous step, hit the "build" and go and grab a hot drink or whatever whilst the code is compiled...!

6. Run Mudlet, and Enjoy. From a terminal window run the mudlet executable, as it is relative to where you had Git clone the code to this will be the file:


Like other systems documented here, it may not be possible to do a "make install" to make this executable work for all users of the system on which it has just been built. At the point of writing the default Qt libraries provided for Debian "Wheezy" are version 4.8.2 which may not match the ones of the Qt-sdk recommended by the Mudlet makers. In the event of problems in that area you may be recommended to build that specific version of the libraries and recompile Mudlet with them - fortunately Qt-Creator does make the latter part relatively straightforward.
