enve

Enve is a new open-source 2D animation software for Linux and Windows. You can use enve to create vector animations, raster animations, and even use sound and video files. Enve was created with flexibility and expandability in mind.

               

Download

You can download the latest enve release for Linux and Windows.

Get Enve Source

Make sure you have git installed on your system.

Clone the enve repository:

git clone https://github.com/MaurycyLiebner/enve

Enter enve directory:

cd enve

Enter the folder with third party dependencies:

cd third_party

Initialize and checkout all submodules:

git submodule update --init

Apply enve-specific library patches (not needed for Windows):

make patch

Building for Linux

Some of the provided terminal commands are applicable only to Ubuntu 16.04 and 18.04. If you are using a different distribution please treat the commands as a general guide.

Skia

Enter the skia directory:

cd skia

Synchronize the skia dependencies:

python tools/git-sync-deps

Install the skia dependencies:

tools/install_dependencies.sh

Install g++-7:

sudo add-apt-repository ppa:jonathonf/gcc
sudo apt-get update
sudo apt-get install g++-7

Download ninja, extract, and set permission for the executable:

wget https://github.com/ninja-build/ninja/releases/download/v1.9.0/ninja-linux.zip
sudo apt-get install unzip
unzip ninja-linux.zip
chmod +x ninja

Create the release build (ninja) files:

bin/gn gen out/Release --args='is_official_build=true is_debug=false extra_cflags=["-Wno-error"] target_os="linux" target_cpu="x64" skia_use_system_expat=false skia_use_system_freetype2=false skia_use_system_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false skia_use_system_harfbuzz=false cc="gcc-7" cxx="g++-7"'

Build a release version of skia (you can use more than 2 threads):

./ninja -C out/Release -j 2

If you want, you can also build a debug version:

bin/gn gen out/Debug --args='extra_cflags=["-Wno-error"] cc="gcc-7" cxx="g++-7"'
./ninja -C out/Debug -j 2

Go back to the third_party folder:

cd ..

Libmypaint

Install libmypaint dependencies:

sudo apt-get install libjson-c-dev intltool pkg-config

Enter libmypaint directory:

cd libmypaint

Set CFLAGS for better optimization:

export CFLAGS='-fopenmp -Ofast -ftree-vectorize -fopt-info-vec-optimized -funsafe-math-optimizations -funsafe-loop-optimizations -fPIC'

Configure libmypaint:

./configure --enable-static --enable-openmp --enable-shared=false

Build libmypaint:

sudo make

Go back to the third_party folder:

cd ..

gperftools

Install packages needed to build gperftools:

sudo apt-get install autoconf automake libtool
sudo apt-get install libunwind-dev

Build gperftools:

cd gperftools
./autogen.sh
./configure --prefix /usr
make

Go back to the third_party folder:

cd ..

Qt

Go to qt.io/download to download Open Source Qt installer. Install Qt 5.12.4 Desktop gcc 64-bit.

Install Qt in the directory of your choice (ex. ~/.Qt)

QScintilla

Build QScintilla:

cd qscintilla/Qt4Qt5
qmake
make -j 2

Go back to the third_party folder:

cd ..

Quazip

cd quazip\quazip
qmake INCLUDEPATH+=$$[QT_INSTALL_HEADERS]/QtZlib
make -j 2

Go back to the main enve directory:

cd ../../../

FFmpeg

Install libraries needed for audio/video decoding/encoding.

sudo add-apt-repository ppa:jonathonf/ffmpeg-4
sudo apt-get update
sudo apt-get install libswresample-dev libswscale-dev libavcodec-dev libavformat-dev libavresample-dev

Other

enve dependencies:

sudo apt-get install libglib2.0-dev

Install libxkbcommon-x11-dev to run QtCreator on Ubuntu 16.04. Otherwise it will not execute properly.

sudo apt-get install libxkbcommon-x11-dev

enve itself

You can either build enve through QtCreator (open enve.pro and setup Relase/Debug Kits), or by running qmake and make directly.

By default qmake is not installed in /usr/bin. You will have to call it by its full path or create a symbolic link:

sudo ln -s your_Qt_dir/5.12.4/gcc_64/bin/qmake /usr/bin/qmake

Build a release version of enve:

cd build/Release
qmake ../../enve.pro
make CC=gcc-7 CPP=g++-7 CXX=g++-7 LD=g++-7
cd ..

Build a debug version of enve (if needed):

cd Debug
qmake CONFIG+=debug ../../enve.pro
make CC=gcc-7 CPP=g++-7 CXX=g++-7 LD=g++-7
cd ..

Now you have successuly build enve and libenvecore along with all the examples. If you wish to create your own executable proceed to the Deployment section.

Deploying for Linux

Make sure you are in the build directory.

Download needed tools

Download and change permission for LinuxDeployQt:

wget https://github.com/probonopd/linuxdeployqt/releases/download/6/linuxdeployqt-6-x86_64.AppImage
chmod +x linuxdeployqt-6-x86_64.AppImage

Copy the enve build into the AppDir:

cp Release/src/app/enve AppDir/usr/bin/
cp -av Release/src/core/*.so* AppDir/usr/lib/

Support older systems (ex. Ubuntu 16.04)

Download patched AppRun binary and an associated library that will link a newer version of libstdc++ on older systems:

wget https://github.com/darealshinji/AppImageKit-checkrt/releases/download/continuous/AppRun-patched-x86_64
mv AppRun-patched-x86_64 AppRun
chmod +x AppRun
cp AppRun AppDir/

wget https://github.com/darealshinji/AppImageKit-checkrt/releases/download/continuous/exec-x86_64.so
mv exec-x86_64.so exec.so
cp exec.so AppDir/usr/optional

Copy your system's version of libstdc++ to your AppDir:

mkdir AppDir/usr/optional/libstdc++
cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 AppDir/usr/optional/libstdc++/

Create AppImage

Create the AppImage using LinuxDeployQt:

./linuxdeployqt-6-x86_64.AppImage AppDir/usr/share/applications/enve.desktop -appimage

You have successfuly created your own enve AppImage!
