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: Should you wish to work on the Mudlet C++ code within the Qt Creator IDE (available as part of the on-line installer for Qt for Open Source projects) you will probably want to delve into the code by opening the qmake project file (the default project system although CMake is also supported). Until somewhere between Mudlet 3.2 and 3.3 this is found in the src subdirectory and was called src.pro - however since it has been renamed to the more obvious mudlet.pro - however the change in name will confuse Qt Creator if it should have the old name file open or stored as the active project in a "session" when a change in working branch happens to switch to the new name (as the src.pro file will disappear). It is simplest to "close" the src project and to open the src/mudlet.pro file if this should be an issue; sadly this may mean that the project build steps have to be re-entered in the relevant part of the IDE.

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 gstreamer0.10-fluendo-mp3 libgstreamer0.10-0 libglu1-mesa-dev \
  mesa-common-dev qtcreator libpulse-dev libglib2.0-dev luarocks
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/src.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/src.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 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

2. Grab latest Mudlet source.

$ cd ~ && 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 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.

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 5.6->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)

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

Notepad++: 
 https://notepad-plus-plus.org/download (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).

Mingw-builds:
 https://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.1/32-bit/threads-posix/dwarf/x32-4.8.1-release-posix-dwarf-rev5.7z/download
extract this to C:\mingw32

Latest msys from:
 http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/
put the msys folder in 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 (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 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

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:\Program Files (x86)\CMake\bin
C:\Qt\5.6\mingw49_32\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:

Hunspell:

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

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

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 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

PCRE:

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

Sqlite:

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

ZLib:

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:

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

ZZIPlib:

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

Building Mudlet from terminal

cd ~/src/Mudlet/src
qmake CONFIG+=debug
make -j 2

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 src.pro (within Mudlet2/src) in Qt Creator, disable shadow builds for both release and debug. Change build type to debug (bottom-left) and compile.

4.Copy Needed DLLs

Copy the following dll's needed to run Mudlet: See above note about alternative install paths before copying.

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

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"
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/src/debug
cp zip.dll ~/src/Mudlet/src/release
cp -r /c/mingw32/lib/lua/5.1/* ~/src/Mudlet/src/debug
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 debug/ folder, or from command line:

cd ~/src/Mudlet/src/debug
./mudlet.exe

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/
