Compiling Mudlet

Key contributing information

Clang format is used to automatically format code submissions using the src/.clang-format style. See here how to enable clang-format with Qt Creator - and make sure to specify the 'File' option for the configuration style.

Branches:

development is the development branch where new features can go.

Workflow:

Fork and submit a PR with your changes (Github tutorial).

Note: if you've previously compiled Mudlet - src/src.pro has been renamed to src/mudlet.pro in Mudlet 3.3.

Travis Integration

Mudlet is hosted on Github and uses Travis for continuous integration by building on a Ubuntu 14.04 LTS Linux and a macOS 10.11 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: Travis builds do not currently package mudlet, so not everything is automated.

Compiling

Compiling on Ubuntu

These instructions will get you setup compiling on Ubuntu. Need a hand? Discord, Join us on Gitter (need a Github account), or forums.

1. Ubuntu 16.04 setup

If you're on Ubuntu 16.04 (Xenial Xerus), install the following. If you're on a newer Ubuntu, skip this step and go to 2. Install dependencies.

 sudo add-apt-repository ppa:beineri/opt-qt58-xenial
 sudo apt update
 sudo apt install qt58-meta-full qt58creator
 source /opt/qt58/bin/qt58-env.sh

2. Install dependencies

sudo apt install git build-essential qt5-default qtmultimedia5-dev qttools5-dev \
  libhunspell-dev lua5.1 liblua5.1-0-dev libpcre3-dev libboost-dev zlib1g-dev cmake \
  libhunspell-dev lua-rex-pcre lua-sql-sqlite3 lua-filesystem lua-zip libyajl-dev \
  libzip-dev libgstreamer0.10-0 libglu1-mesa-dev \
  mesa-common-dev qtcreator libpulse-dev libglib2.0-dev luarocks libboost-all-dev
sudo apt install gstreamer0.10-fluendo-mp3 # may not work on newer Ubuntu
sudo luarocks install luautf8

3. Get Mudlet source

git clone --recursive https://github.com/Mudlet/Mudlet.git mudlet

4. Create a build directory

 cd mudlet
 mkdir build
 cd build

5. Run the following commands, depending on which build system you want to use

EITHER:

cmake ..

OR:

qmake CONFIG+=debug ../src/mudlet.pro

THEN:

make -j `nproc`

5. Start the application you have just compiled - enjoy

./mudlet

Optionally - install ccache and enable it for quicker compilation - it especially helps when you're switching between Git branches.

Compiling on macOS

These instructions will get you setup compiling on macOS. Need a hand? Join us on Gitter (need a Github account), Discord server or forums otherwise.

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 --recursive https://github.com/Mudlet/Mudlet.git 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}"
 CI/travis.osx.before_install.sh
 CI/travis.osx.install.sh
 sudo luarocks-5.1 install lrexlib-pcre
 sudo luarocks-5.1 install luasql-sqlite3
 sudo luarocks-5.1 install luautf8

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)

EITHER:

 qmake ../src/mudlet.pro

OR:

 cmake ..

THEN:

 make -j `sysctl -n hw.ncpu`

6. Enjoy

The Mudlet.app is now available in Finder for launching.

Compiling on Debian 'Sid'

1. Install required packages from main repo.

sudo apt-get install build-essential git liblua5.1-dev zlib1g-dev libhunspell-dev libpcre3-dev \
libzip-dev libboost-dev libyajl-dev libpulse-dev lua-rex-pcre lua-filesystem lua-zip \
lua-sql-sqlite3 qt5-default qtmultimedia5-dev qttools5-dev luarocks

sudo luarocks install luautf8  

2. Grab latest Mudlet source.

mkdir ~/projects && cd ~/projects && git clone --recursive https://github.com/Mudlet/Mudlet.git mudlet

3. Build Mudlet.

cd ~/projects/mudlet/src

qmake

make

sudo make install

Compiling on Debian 9 'Stretch'

1. Install required packages.

sudo apt-get install build-essential git liblua5.1-dev zlib1g-dev libhunspell-dev libpcre3-dev \
libzip-dev libboost-dev libyajl-dev libpulse-dev lua-rex-pcre lua-filesystem lua-zip \
lua-sql-sqlite3 qt5-default qtmultimedia5-dev qttools5-dev luarocks

sudo luarocks install luautf8  

2. Get Mudlet source.

mkdir ~/source && cd ~/source

git clone --recursive https://github.com/Mudlet/Mudlet.git mudlet

Note: the line above will check out `development` branch source code, and this might not always be stable. You can check out the latest release source code using this command:

git clone --recursive --branch master https://github.com/Mudlet/Mudlet.git mudlet

3. Build Mudlet.

mkdir ~/source/mudlet/build && cd ~/source/mudlet/build

qmake ../src/mudlet.pro

make -j `nproc`

sudo make install

After these steps you can run Mudlet by typing:

mudlet

Compiling on 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

makepkg
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 on Gentoo

An overlay containing Mudlet is available for compiling Mudlet on Gentoo.

Compiling on Windows 10

These instructions will get you setup compiling on Windows. Need a hand? Join us on Gitter (need a Github account), Discord server or forums otherwise.

MinGW is able to make use of all the cores on your system to do parallel compilation - throughout this tutorial a dualcore system is assumed, but if you have more than 2 cores set the -j # to the number of threads you need. For example, on an AMD Ryzen that has 6 cores and 12 threads, -j 12 will make full use of the CPU.

1.Download & Install the Prerequisites

Qt:
 http://download.qt.io/official_releases/online_installers/qt-unified-windows-x86-online.exe
Run the installer and de-select everything and just select:
 Qt→Qt 5.9.1→MinGW 5.3.0 (32 bit)
 Tools→MinGW 5.3.0

In this tutorial, it is installed in C:\Qt\ (so you will have C:\Qt\5.x)

7Zip:
 http://www.7-zip.org/a/7z1602-x64.msi

Notepad++:
 https://notepad-plus-plus.org/download
Recommended if you don't have a good source editor installed already (it is released under a GPL License).

Latest msys from:
 http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/

Right-click, select 7-Zip -> Extract files... and extract the msys folder using 7zip into C:\mingw32, so you get C:\mingw32\msys:

CMake:
 http://www.cmake.org/files/v3.0/cmake-3.0.0-win32-x86.exe

Python:
 https://www.python.org/ftp/python/2.7.11/python-2.7.11.msi

2.Download libraries in MSYS

Open MSYS - doubleclick msys.bat in the C:\mingw32\msys folder. It might take a while to come up. Copy the lines below when it does 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 https://github.com/hunspell/hunspell/archive/v1.4.1.tar.gz
wget http://www.lua.org/ftp/lua-5.1.5.tar.gz
wget --no-check-certificate https://sourceforge.net/projects/pcre/files/pcre/8.38/pcre-8.38.tar.gz/download
wget http://zlib.net/zlib-1.2.11.tar.gz
wget http://www.sqlite.org/2013/sqlite-autoconf-3071700.tar.gz
wget --no-check-certificate https://launchpad.net/ubuntu/+archive/primary/+files/libzip_0.11.2.orig.tar.gz
wget --no-check-certificate --output-document yajl-2.0.1.tar.gz https://github.com/lloyd/yajl/tarball/2.0.1
wget --no-check-certificate https://sourceforge.net/projects/zziplib/files/zziplib13/0.13.62/zziplib-0.13.62.tar.bz2/download
wget --no-check-certificate https://indy.fulgan.com/SSL/openssl-1.0.2k-i386-win32.zip

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
 /c/Program\ Files/7-Zip/7z -oopenssl-1.0.2k e openssl-1.0.2k-i386-win32.zip

Boost:

wget --no-check-certificate https://sourceforge.net/projects/boost/files/boost/1.60.0/boost_1_60_0.tar.gz/download
/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/boost

3.Compiling libraries

Environment Settings

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

C:\Python27
C:\mingw32\bin
C:\mingw32\lib
C:\Program Files (x86)\CMake\bin
C:\Qt\5.9.1\mingw53_32\bin
C:\Qt\Tools\mingw530_32\bin

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

Note: WIP: most of Mudlet dependencies condensed for less manual work. This is not ready yet - do not use.

cd hunspell-1.4.1
./configure --prefix=/c/mingw32 && make -j 2 && make install
cd ../pcre-8.38
./configure --prefix=/c/mingw32 && make -j 2 && make install

MSYS Compilations

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

cd ~/src

Hunspell:

cd hunspell-1.4.1
./configure --prefix=/c/mingw32 && make -j 2 && make install

YAJL: First, remove all the windows specific compiler settings with:

cd ../lloyd-yajl-f4b2b1a/
powershell -Command "(Get-Content CMakeLists.txt -Raw) -replace '\/W4' -replace '(?<=SET\(linkFlags)[^\)]+' -replace '\/wd4996 \/wd4255 \/wd4130 \/wd4100 \/wd4711' -replace '(?<=SET\(CMAKE_C_FLAGS_DEBUG .)\/D \DEBUG \/Od \/Z7', '-g' -replace '(?<=SET\(CMAKE_C_FLAGS_RELEASE .)\/D NDEBUG \/O2', '-O2' | Out-File -encoding ASCII CMakeLists.txt"

Then compile:

mkdir build
cd build
cmake -G "MSYS Makefiles" ..

make
cp yajl-2.0.1/lib/* /c/mingw32/lib/
cp -R yajl-2.0.1/include/* /c/mingw32/include/

Lua: edit src\lua-5.1.5\Makefile, change INSTALL_TOP= /usr/local to INSTALL_TOP= /c/mingw32

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

cd ../../lua-5.1.5
make mingw
make install

PCRE:

cd ../pcre-8.38
./configure --prefix=/c/mingw32 && make -j 2 && make install

Sqlite:

cd ../sqlite-autoconf-3071700
./configure --prefix=/c/mingw32 && make -j 2 && make install

ZLib:

cd ../zlib-1.2.11
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

LibZip:

cd ../libzip-0.11.2/
./configure --prefix=/c/mingw32 && make -j 2 && make install
cp lib/zipconf.h /c/mingw32/include

ZZIPlib:

cd ../zziplib-0.13.62
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 --recursive https://github.com/Mudlet/Mudlet.git
cd Mudlet/src

NOTE: If you install any of the above in a directory other than /c/mingw32, it is necessary to override some of the default include/lib paths that qmake sets up. To do so, you'll need to append a number of INCLUDEPATH and LIBPATH parameters to the qmake call.

Example (installed in an F: drive):

qmake CONFIG+=debug INCLUDEPATH+=/f/mingw32/include INCLUDEPATH+=/f/mingw32/lib/include LIBPATH+=/f/mingw32/lib LIBPATH+=/f/mingw32/lib/lib LIBPATH+=/f/mingw32/bin

Building Mudlet from QtCreator

Open C:\mingw32\msys\home\<username>\src\Mudlet\src\mudlet.pro in Qt Creator, enable Debug and Release builds and hit Configure Project:

Press Ctrl+5 and update project settings for the # of cores/threads available to your system:

Hit run:

Click on Compile Output to see progress on compiling:

This'll take ~10min, after which Mudlet will launch! But it's not completely ready yet - close it and follow more:

4.Copy Needed DLLs

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 http://keplerproject.github.io/luarocks/releases/luarocks-2.4.0-win32.zip
unzip luarocks-2.4.0-win32.zip

Open up the Windows command line cmd 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"
luarocks install luautf8

Back in the msys command line:

cd ~/src
wget --no-check-certificate https://github.com/rjpcomputing/luazip/archive/master.zip
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/build-mudlet-Desktop_Qt_5_9_1_MinGW_32bit-Debug/debug
cp zip.dll ~/src/Mudlet/build-mudlet-Desktop_Qt_5_9_1_MinGW_32bit-Release/release
cp -r /c/mingw32/lib/lua/5.1/* ~/src/Mudlet/build-mudlet-Desktop_Qt_5_9_1_MinGW_32bit-Debug/debug
cp -r /c/mingw32/lib/lua/5.1/* ~/src/Mudlet/build-mudlet-Desktop_Qt_5_9_1_MinGW_32bit-Release/release
cp -r ~/src/Mudlet/src/mudlet-lua/ ~/src/Mudlet/build-mudlet-Desktop_Qt_5_9_1_MinGW_32bit-Debug
cp -r ~/src/Mudlet/src/mudlet-lua/ ~/src/Mudlet/build-mudlet-Desktop_Qt_5_9_1_MinGW_32bit-Release

You're done! Press the green Run button again in Qt Creator (bottom-right) and a Mudlet window should come up without any errors.

Uninstalling

To uninstall, remove the following folders:

C:\LuaRocks
C:\mingw32
C:\Qt

Setting up IDEs

CLion

If you'd like to use CLion and it is giving the following error:

By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5Core", but
CMake did not find one.

Could not find a package configuration file provided by "Qt5Core" with any
of the following names:

Qt5CoreConfig.cmake
qt5core-config.cmake

Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set
"Qt5Core_DIR" to a directory containing one of the above files.  If
"Qt5Core" provides a separate development package or SDK, be sure it has
been installed.

You can fix this by setting -DCMAKE_PREFIX_PATH=<your Qt + version + compiler location>. For example: -DCMAKE_PREFIX_PATH=/home/vadi/Programs/Qt/5.8/gcc_64/
