About

A simple vector graphics animation program.

Dependencies

Getting the Latest Code

You can find the code on GitLab.

To clone with git:

git clone --recursive https://gitlab.com/mattbas/glaxnimate.git

Building

Generic Overview

If you are building from git, ensure your submodules are up to date

git submodule update --init --recursive

Standard CMake build commands work

mkdir build
cd build
cmake ..
make -j 4 # This uses 4 cores to compile

It will produce the executable bin/glaxnimate relative to the build directory

Deb-based systems (Ubuntu, Debian, etc)

Install the dependencies:

apt-get install -y g++ cmake qtbase5-dev qttools5-dev libqt5svg5-dev \
qt5-image-formats-plugins libpython3-dev zlib1g-dev libpotrace-dev \
libarchive-dev libavformat-dev libswscale-dev libavcodec-dev libavutil-dev

The generic cmake commands listed above should work.

Arch-based systems

Install the dependencies:

pacman -S git base-devel cmake python zlib hicolor-icon-theme \
potrace ffmpeg qt5-base qt5-tools qt5-imageformats qt5-svg

The generic cmake commands listed above should work.

MacOS

Install the dependencies with homebrew:

brew install cmake qt python potrace ffmpeg libarchive

Build with cmake, specifying the Qt installation path:

mkdir build
cd build
cmake .. -DQt5_DIR="$(brew --prefix qt@5)/lib/cmake/Qt5" -DCMAKE_PREFIX_PATH="$(brew --prefix qt@5)/lib/cmake/Qt5Designer"
make

To simplify the build process, you can also use the provided scrips:

./deploy/mac_build.sh deps
./deploy/mac_build.sh configure
./deploy/mac_build.sh build

Windows

Install MSYS2, select "Mingw-w64 64 bit" when asked, and run these commands on a it:

# Set up dependencies
pacman --noconfirm -Sy
pacman --noconfirm -Su
# Restart msys2 before continuing
pacman --noconfirm -S \
    git zip base-devel \
    unzip               \
    mingw-w64-x86_64-qt5 \
    mingw-w64-x86_64-zlib \
    mingw-w64-x86_64-cmake \
    mingw-w64-x86_64-python \
    mingw-w64-x86_64-potrace \
    mingw-w64-x86_64-ffmpeg   \
    mingw-w64-x86_64-toolchain \
    mingw-w64-x86_64-python-pip \
    mingw-w64-x86_64-libarchive  \
    mingw-w64-x86_64-libimagequant

# Build
# cd to where the code is
mkdir build
cd build
cmake.exe .. \
    -DQt5_DIR=/mingw64/lib/cmake/Qt5 \
    -DZLIB_LIBRARY=/mingw64/lib/libz.a \
    -DCMAKE_PREFIX_PATH="/mingw64/lib/" \
    -DZLIB_INCLUDE_DIR=/mingw64/include \
    -G "MSYS Makefiles"
make

# Copy library files because windows is weird like that
windeployqt.exe bin/glaxnimate.exe
cp /mingw64/bin/*.dll bin
cp ./external/Qt-Color-Widgets/libQtColorWidgets.dll bin

To simplify the build process, you can also use the provided scrips:

./deploy/win_build.sh deps
./deploy/win_build.sh configure
./deploy/win_build.sh build

Android

Note that these instructions have been tested on an Ubuntu host, on different systems things might vary.

Setting up Java

Ensure you have the JVM and JDK installed on your system.

sudo apt install default-jdk

Installing Qt

See also https://doc.qt.io/qt-5/android-getting-started.html.

Download the Qt Installer for the open source edition https://www.qt.io/download-open-source.

For some reson Qt wants you to have an account even if you install the open source version so you might have to set that up;

Install Qt Creator and Qt 5 Android. Qt versions in the 5.12.* line should work, some newer Qt versions have issues with the android build tools so it's better to stick with 5.12.

Select "Custom Installation", then on the following page check Qt > Qt 5.12.11 (or whatever version you prefer) > Android. You can also install additional components such as Qt for Desktop and such.

Accept the licenses and proceed to install.

Setting up Qt for Android

Once Qt is installed, you can download and install the Android development tools from Qt Creator.

You can follow the instructions from here: https://doc.qt.io/qtcreator/creator-developing-android.html#specifying-android-device-settings.

From Qt Creator:

Building

You need to know the paths for Qt and Android stuff, or use cmake_helper.py to simplify the process

mkdir build
cd build

../src/android/tools/cmake_helper.py --abi x86 --qt 5.12.11 ..
make -j8

Running

There are some utility make targets to run the apk

# List available virtual devices (you need to create them separately)
make android_avd_list
# Start virtual device ("device" is from `make android_avd_list`)
make android_avd_start DEVICE="device"

# Build the APK
make glaxnimate_apk -j8
# Install and run the APK on the running AVD
make android_install
# Attach to the output
make android_log

Once you have an AVD running (or a debug phone connected) you can run a single line:

make glaxnimate_apk -j8 && make android_install && make android_log

Troubleshooting

Could not determine java version

Qt downloads an old version of gradle, so if you get an error that your Java version cannot be recognize find the file gradle-wrapper.properties and update it to version 5.1 or later.

Incompatible target / Undefined reference / Redefinition

Sometimes qmake messes up the build, the best option is to remove the build directory created by Qt Creator and rebuild.

Invalid MinSdkVersion

Depending on which version of the Android SDK you have, you might have to select a different value in src/android/android/AndroidManifest.xml.

libc++.so not found

The Android toolkit stuff has some wrong paths, it can be fixed like this:

sudo mkdir /opt/android 
sudo ln -s $HOME/Android/Sdk/ndk/21.1.6352462/ /opt/android/android-ndk-r19c

Where $HOME/Android/Sdk/ndk/21.1.6352462/ is the directory that Qt creator used to install the Android NDK, and /opt/android/android-ndk-r19c is the directory mentioned in the error message.

Cannot set up Android, not building an APK / Application binary is not in output directory

Sometimes it does that, building again usually fixes it.
