Setting up the development environment for GNU/Linux

Required software

Building OpenToonz from source requires the following dependencies: - Git - GCC or Clang - CMake (3.4.1 or newer). - Qt5 (5.9 or newer) - Boost (1.55 or newer) - SDL2 - LibPNG - SuperLU - Lzo2 - FreeType - LibMyPaint (1.3 or newer)

Installing Dependencies on Debian / Ubuntu

$ sudo apt-get install build-essential git cmake pkg-config libboost-all-dev qt5-default qtbase5-dev libqt5svg5-dev qtscript5-dev qttools5-dev qttools5-dev-tools libqt5opengl5-dev qtmultimedia5-dev libsuperlu-dev liblz4-dev libusb-1.0-0-dev liblzo2-dev libpng-dev libjpeg-dev libglew-dev freeglut3-dev libsdl2-dev libfreetype6-dev

Notes: * It's possible we also need libgsl2 (or maybe libopenblas-dev)

TODO:

• libmypaint package

Installing Dependencies on Fedora

(it may include some useless packages)

$ dnf install gcc gcc-c++ automake git cmake boost boost-devel SuperLU SuperLU-devel lz4-devel lzma libusb-devel lzo-devel libjpeg-turbo-devel libGLEW glew-devel freeglut-devel freeglut SDL2 SDL2-devel freetype-devel libpng-devel qt5-qtbase-devel qt5-qtsvg qt5-qtsvg-devel qt5-qtscript qt5-qtscript-devel qt5-qttools qt5-qttools-devel qt5-qtmultimedia-devel blas blas-devel

TODO:

• libmypaint package

Installing Dependencies on ArchLinux

$ sudo pacman -S base-devel git cmake boost boost-libs qt5-base qt5-svg qt5-script qt5-tools qt5-multimedia lz4 libusb lzo libjpeg-turbo glew freeglut sdl2 freetype2
$ sudo pacman -S blas cblas

From AUR, using eg. yaourt:

$ yaourt -S superlu libmypaint

Notes: * ArchLinux has blas split into blas and cblas.

Installing Dependencies on openSUSE

$ zypper in boost-devel cmake freeglut-devel freetype2-devel gcc-c++ glew-devel libQt5OpenGL-devel libSDL2-devel libjpeg-devel liblz4-devel libpng16-compat-devel libqt5-linguist-devel libqt5-qtbase-devel libqt5-qtmultimedia-devel libqt5-qtscript-devel libqt5-qtsvg-devel libtiff-devel libusb-devel lzo-devel openblas-devel pkgconfig sed superlu-devel zlib-devel

TODO:

• libmypaint package

Build instructions

Cloning the GIT Tree

$ git clone https://github.com/opentoonz/opentoonz

Copying the 'stuff' Directory

TODO: some parts should really be installed in $prefix/ instead... and some other in various cache or user-local places. cf. https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html Until then we just follow the Win32/OSX layout.

The ~/.config/OpenToonz/ directory contains your settings, work and other files.

Initialize this path with the folling commands:

$ mkdir -p $HOME/.config/OpenToonz
$ cp -r opentoonz/stuff $HOME/.config/OpenToonz/

Currently this is required to run OpenToonz.

Creating SystemVar.ini

TODO: fix the code to discover it automatically

$ cat << EOF > $HOME/.config/OpenToonz/SystemVar.ini
[General]
OPENTOONZROOT="$HOME/.config/OpenToonz/stuff"
OpenToonzPROFILES="$HOME/.config/OpenToonz/stuff/profiles"
TOONZCACHEROOT="$HOME/.config/OpenToonz/stuff/cache"
TOONZCONFIG="$HOME/.config/OpenToonz/stuff/config"
TOONZFXPRESETS="$HOME/.config/OpenToonz/stuff/projects/fxs"
TOONZLIBRARY="$HOME/.config/OpenToonz/stuff/projects/library"
TOONZPROFILES="$HOME/.config/OpenToonz/stuff/profiles"
TOONZPROJECTS="$HOME/.config/OpenToonz/stuff/projects"
TOONZROOT="$HOME/.config/OpenToonz/stuff"
TOONZSTUDIOPALETTE="$HOME/.config/OpenToonz/stuff/studiopalette"
EOF

Note the generated file must not actually contain $HOME, this expands to an absolute path in the generated file.

Building LibTIFF

TODO: make sure we can use the system libtiff instead and remove this section. Features from the modified libtiff are needed currently, so this isn't a simple switch.

$ cd opentoonz/thirdparty/tiff-4.0.3
$ ./configure --with-pic --disable-jbig
$ make -j$(nproc)
$ cd ../../

Building OpenToonz

$ cd toonz
$ mkdir build
$ cd build
$ cmake ../sources
$ make -j$(nproc)

The build takes a lot of time, be patient.

Troubleshooting Build Errors

If something doesn't compile or link, please run make this way to help spot the problem:

$ LANG=C make VERBOSE=1

Debug Build

If you need to debug the application, you should be able to use cmake -DCMAKE_BUILD_TYPE=Debug.

Running OpenToonz

You can now run the application:

$ LD_LIBRARY_PATH=./lib/opentoonz:$LD_LIBRARY_PATH ./bin/OpenToonz_1.1

Performing a System Installation

The steps above show how to run OpenToonz from the build directory, however you may wish to install OpenToonz onto your system.

OpenToonz will install to /opt/opentoonz by default, to do this run:

$ sudo make install

Then you can launch OpenToonz by running /opt/opentoonz/bin/opentoonz.

You can change the installation path by modifying the CMAKE_INSTALL_PREFIX CMake variable.

Linux Package Definitions

It may be helpful to use existing packages as a reference when creating a package for your own distribution.
