Dependencies

• C++17 compiler
• Latest QT6
• Various libraries for Linux & macOS, see below
• On Windows all the libraries are included in the repository

For debian/ubuntu, those packages are needed

libavformat-dev libavutil-dev libbz2-dev libeb16-dev libhunspell-dev \
liblzma-dev liblzo2-dev libopencc-dev libvorbis-dev \ 
libx11-dev libxtst-dev libzim-dev libzstd-dev qt6-5compat-dev \
qt6-base-dev qt6-multimedia-dev qt6-speech-dev qt6-svg-dev \
qt6-tools-dev qt6-tools-dev-tools qt6-webchannel-dev \
qt6-webengine-dev x11proto-record-dev zlib1g-dev

In other words, those libraries

• Qt6 (with webengine)
• ffmpeg
• libzim
• xapian
• hunspell
• opencc
• libeb
• libvorbis
• x11 (linux only)

And a few compression libraries:

• xz (lzma)
• bzip2
• lzo2
• zlib

CMake Build

cd goldendict-ng && mkdir build_dir
# config step
cmake -S . -B build_dir \
      --install-prefix=/usr/local/ \
      -DCMAKE_BUILD_TYPE=Release
# actual build
cmake --build build_dir --parallel 7

cmake --install ./build_dir/

Feature flags

Append -D{flag_names}=ON/OFF to cmake's config step

Available flags:

• WITH_FFMPEG_PLAYER "Enable support for FFMPEG player"

• WITH_EPWING_SUPPORT "Enable epwing support"

• WITH_XAPIAN "enable Xapian support"

• WITH_ZIM "enable zim support"

• USE_SYSTEM_FMT "use system fmt instead of bundled one"

• USE_SYSTEM_TOML "use system toml++ instead of bundled one"

Windows

Install Qt6(msvc) through the standard installer

Pass those parameters to cmake, the path should be changed to your actual installation paths

-DCMAKE_PREFIX_PATH=F:\Qt\6.4.1\msvc2019_64

Usewindeployqt.exe {your_build_dir}/goldendict.exe which will copy the qt related .dll and other necessary files automatically.

Due to the winlibs are built on Release mode, there are troubles to build GoldenDict on Debug mode.

macOS

Similar to Linux build, but need macdeployqt ./goldendict.app to copy necessary dependencies to the app bundle.

Qmake

git clone https://github.com/xiaoyifang/goldendict-ng.git

Build Steps

Notice: All additional configs for qmake that must be combined in one of pass config options to qmake:

qmake6 "CONFIG+=release"
make

For ARM macOS, QMAKE_APPLE_DEVICE_ARCHS="arm64" should be passed to qmake.

Building with Chinese conversion support

To add Chinese conversion support you need at first install libopencc-dev package, then pass "CONFIG+=chinese_conversion_support" to qmake.

sudo apt-get install libopencc-dev

Building with Zim dictionaries support

To add Zim formats support you need libzim, then pass "CONFIG+=zim_support" to qmake

Note: Some linux distros do not support latest zim version, so you need to compile from latest source. On Windows, you can use vcpkg to compile the libzim

vcpkg install libzim:x64-windows

and copy the corresponding(debug/release) library to the winlibs/lib folder. the zim's include directory to the winlibs/include directory.

Building without Epwing format support

If you have problem building with libeb-dev package, you can pass "CONFIG+=no_epwing_support" to qmake in order to disable Epwing format support

Building without internal audio players

If you have problem building with FFmpeg (for example, very old linux distro), you can pass "CONFIG+=no_ffmpeg_player" to qmake in order to disable FFmpeg internal audio player back end.

If you have problem building with Qt5 Multimedia or experience GStreamer run-time errors (for example, Ubuntu 14.04), you can pass "CONFIG+=no_qtmultimedia_player" to qmake in order to disable Qt Multimedia internal audio player back end.

Building with xapian

build xapian from source, download and extract the xapian-core source code.

./configure
make 
make install

On Windows, vcpkg install xapian:x64-windows and copy the libs/dlls into the winlibs A precompiled version of xapian lib has provided in winlibs.

On Linux, install libxapian-dev package using package manager.

On Mac, use homebrew to install xapian brew install xapian

Goldendict-ng has used xapian as the default and the only one fulltext engine.

use iconv (recommend to enable)

use CONFIG+=use_iconv to enable this feature. when enabled ,iconv will be used to convert encoding other than the QTextCodec(which will be deprecated in future Qt version)

qmake "CONFIG+=use_iconv"

when enabled ,iconv should be installed on the platform at the same time.

use breakpad

use CONFIG+=use_breakpad to enable this crash dump. when enabled breakpad, goldendict will generate a crash dump alongside with Goldendict in the crash directory.

on Windows: vcpkg install breakpad:x64-windows-release and copy the installed packages into thirdparty/breakpad directory. with a structure like this:

├─breakpad
│  ├─include
│  │  ├─client
│  │  │  └─windows
│  │  │      ├─common
│  │  │      ├─crash_generation
│  │  │      ├─handler
│  │  │      └─sender
│  │  ├─common
│  │  │  └─windows
│  │  └─google_breakpad
│  │      ├─common
│  │      └─processor
│  └─lib

on Mac/Linux: vcpkg can also be used or you can just install breakpad from source or use precompiled packages.

Then enable google breakpad like this with qmake:

qmake "CONFIG+=use_breakpad"

Build with VS2019

Install QT tool for VS from VS extension

steps:

• configure qt path toolbar Extensions=>Qt VS Tools=>Options=>versions. add qt installation folder

• Open pro project file directly throughttoolbar Extensions=>Qt VS Tools=>Open Qt Project file(.pro)

ref: 1

build

after successfully build,in the target folder(where goldendict.exe resides) ,run windeployqt which copy all the necessary files to this folder. and copy other missing dlls to this folder. you can click the exe to verify the application can run .

after alll this ,you can debug the application normally.
