Compiling cbird

You will need to compile cbird to get the most format support and perhaps better platform integration (like theme) compared to the AppImage.

Compiling: Dependencies

  • qt6 (6.5 preferred)
  • opencv2, 2.4.13.7
  • FFmpeg
  • quazip

Compiling: Linux (Ubuntu 22.04)

The easiest way is to use a distro that has Qt 6. However, the qt.io distribution or building from source can have additional image formats.

This recipe is for Ubuntu 22.04 which includes a working FFmpeg and Qt6 version.

1.1 Packages

apt-get install git cmake g++ qt6-base-dev qt6-base-private-dev libqt6core5compat6-dev libgl-dev libpng-dev libjpeg-turbo8-dev libtiff5-dev libopenexr-dev libexiv2-dev libncurses-dev

1.2 Compiling OpenCV

wget https://github.com/opencv/opencv/archive/2.4.13.7.zip
unzip 2.4.13.7.zip
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=Release -D WITH_FFMPEG=OFF -D WITH_OPENEXR=OFF -D WITH_JASPER=OFF -D WITH_GSTREAMER=OFF -D ENABLE_FAST_MATH=1 -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF -DBUILD_DOCS=OFF CMAKE_INSTALL_PREFIX=/usr/local ../opencv-2.4.13.7/
make -j8
sudo make install

1.3 Compiling quazip

# if you compiled qt6 then
export Qt6_DIR=<path-to-qt6>

git clone https://github.com/stachenov/quazip
cd quazip
cmake -DQUAZIP_QT_MAJOR_VERSION=6 .
make -j8
sudo make install

1.4a Using System FFmpeg

Note: not possible at the moment on 22.04, FFmpeg version is too old.

apt-get install libavformat-dev libswscale-dev

1.4b Compiling FFmpeg

The latest ffmpeg may not work due to deprecations, use the revision tag for a known good version. For GPU video decoding (Nvidia) we also need nv-codecs-headers and --enable-cuvid.

With some additional flags (not shown here) you can get more codec support.

sudo apt-get install nasm libfribidi-dev libsdl2-dev libharfbuzz-dev libfreetype-dev

git clone https://github.com/FFmpeg/nv-codec-headers.git
cd nv-codec-headers
make && sudo make install

git clone https://github.com/FFmpeg/FFmpeg.git
cd FFmpeg
git checkout 1bcb8a7338 # optional, last working version
./configure --enable-gpl --enable-ffplay --enable-cuvid --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libharfbuzz  --disable-static --enable-shared
make -j8
sudo make install

1.5 Compiling cbird

git clone https://github.com/scrubbbbs/cbird
cd cbird
git checkout v0.7.0 # optional, last release version
qmake6
make -j8
sudo make install

1.6 Installing Supporting Files (Optional)

cbird -install

Compiling: Windows

The Windows version is compiled using MXE cross-compiler from a Linux host. MXE has an apt repository for dependencies to make this easier, but it might not be available for your distro.

Once mxe is installed it works like the Linux build. You must set MXE_DIR to the path to mxe. The windows/mxe.env script sets the shell environment to redirect build tools like qmake and cmake.

2.1 Packages

apt-get install lzip intltool wine64

2.2a Installing mxe from source

cd /path/to/stuff

apt-get install libpcre3-dev
git clone https://github.com/mxe/mxe.git
cd mxe
make MXE_TARGETS='x86_64-w64-mingw32.shared' cc qt6-qtbase qt6-qt5compat exiv2 sdl2

export MXE_DIR=/path/to/stuff/mxe

2.2b Installing mxe from repos

sudo apt-key adv \
    --keyserver keyserver.ubuntu.com \
    --recv-keys 86B72ED9 && \
sudo add-apt-repository \
    "deb [arch=amd64] https://pkg.mxe.cc/repos/apt `lsb_release -sc` main" && \
sudo apt-get update

apt install mxe-x86-64-w64-mingw32.shared-cc mxe-x86-64-w64-mingw32.shared-qt6-qtbase mxe-x86-64-w64-mingw32.shared-quazip mxe-x86-64-w64-mingw32.shared-exiv2

export MXE_DIR=/usr/lib/mxe

2.3 Cross-compiling OpenCV

Additional flags added for CPU compatibility in the release package (optional).

cd cbird
source windows/mxe.env
mkdir -p _libs-win32/build-opencv
cd _libs-win32
unzip <opencv-2.4.13.7.zip>
cd build-opencv
cmake -D CMAKE_BUILD_TYPE=Release -D WITH_FFMPEG=OFF -D WITH_OPENEXR=OFF -D WITH_GSTREAMER=OFF -D ENABLE_FAST_MATH=1 -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF -DBUILD_DOCS=OFF -D CMAKE_CXX_FLAGS_RELEASE="-march=westmere -Ofast" -D CMAKE_C_FLAGS_RELEASE="-march=westmere -Ofast" -D ENABLE_SSSE3=ON -D ENABLE_SSE41=ON -D ENABLE_SSE42=ON ../opencv-2.4.13.7/
make -j8
make install

2.4 Cross-compiling FFmpeg

Optional, if mxe ffmpeg version is incompatible.

source windows/mxe.env
cd _libs-win32
git clone https://github.com/ffmpeg/FFmpeg.git
cd FFmpeg
./configure --cross-prefix=x86_64-w64-mingw32.shared- --enable-cross-compile --arch=x86_64 --target-os=mingw32 --enable-shared --disable-static --yasmexe=x86_64-w64-mingw32.shared-yasm --disable-debug --disable-pthreads --enable-w32threads --disable-doc --enable-gpl --extra-libs='-mconsole' --extra-ldflags="-fstack-protector" --prefix=../build-mxe

2.5 Cross-compiling quazip

Optional, if mxe quazip version incompatible.

source windows/mxe.env
cd _libs-win32
git clone https://github.com/stachenov/quazip
cd quazip
cmake -DQUAZIP_QT_MAJOR_VERSION=6 -DCMAKE_INSTALL_PREFIX=../build-mxe .
make -j8
make install

2.6 Cross-compiling cbird

cd cbird
source windows/mxe.env
qmake
make -j8
make install # build/update portable dir in _win32/cbird/

Compiling: Mac OS X

3.1 Install Homebrew

Follow Instructions Here

3.2 Installing packages

brew install qt6 quazip ffmpeg exiv2 grealpath trash

3.3 Compiling OpenCV

See Compiling opencv, in addition you may need this trivial patch to fix the build.

Apply patch to fix the build ./cbird/mac/opencv.diff

cd opencv-2.xx.x
patch -p1 < (..)/cbird/mac/opencv.diff

Add -DCMAKE_OSX_DEPLOYMENT_TARGET=11.0 to suppress link warnings.

3.4 Compiling cbird

See Compiling cbird

Additionally, make portable will build the release binaries in _mac/cbird/

Compiling: Linux AppImage

The AppImage is built using linuxdeployqt on ubuntu 18.04 LTS.

QEMU is used, with cpu target "Westmere" to ensure binary compatibility with older systems (no AVX).
