crengine - CREngine (DOM/XML/CSS ebook rendering library) sources cr3gui - CR3 with CR3GUI for e-ink devices sources cr3qt - CR3 with Qt based GUI cr3wx - CR3 with wxWidgets based GUI thirdparty - third party libraries, to use if not found in system (zlib, libpng, libjpeg, freetype, etc...) thirdparty_repo - repository for third party libraries deployments thirdparty_unman - unmanaged third party libraries tinydict - small library for .dict file format support tools - miscellaneous configuration files android - Android frontend common: zlib, libpng, libjpeg, freetype, harfbuzz, fribidi, libunibreak, utf8proc, zstd cr3gui/xcb: libxcb, fontconfig cr3gui/nanoX: libnanoX cr3/Qt: fontconfig, qt5-base, qt5-tools cr3/wx: fontconfig, wxWidgets 3.0 e.g., for Ubuntu you may use
$ sudo apt install build-essential git cmake curl pkg-config zlib1g-dev libpng-dev libjpeg-dev libfreetype6-dev libfontconfig1-dev libharfbuzz-dev libfribidi-dev libunibreak-dev libzstd-dev libutf8proc-dev To build Qt frontend:
$ sudo apt install qtbase5-dev qttools5-dev To build wxWidgets frontend:
$ sudo apt install libwxgtk3.0-gtk3-dev Debian based packages included to project:
packages/ubuntu -- debian package for Ubuntu, with Qt frontend packages/openinkpot -- debian package for OpenInkpot, with XCB frontend To build debian package, copy one of package descriptions from packages directory:
cp -r packages/ubuntu/debian debian Then, package can be built using `debuild` command. - Deploy/update third party libraries: in terminal call script thirdparty-deploy.sh
In Windows can be used git bash terminal
$ ./thirdparty-deploy.sh - Use Android Studio - open subdirectory "android" as Android Studio project
Ensure that you have Android SDK and NDK installed
In case the installed libraries are outdated, run the thirdparty-deploy.sh script to download libraries sources of the recommended versions. In this case, the build system will build static libraries that were not found in the system.
$ ./thirdparty-deploy.sh Building Qt version (qtbase5-dev, qttools5-dev should be installed)
mkdir qtbuild cd qtbuild cmake -D GUI=QT5 -D CMAKE_BUILD_TYPE=Release -D MAX_IMAGE_SCALE_MUL=2 -D DOC_DATA_COMPRESSION_LEVEL=3 -D DOC_BUFFER_SIZE=0x1400000 -D CMAKE_INSTALL_PREFIX=/usr .. make sudo make install Building Qt version, in DEBUG mode

- Update MSYS2:
Run "MSYS2 MSYS" from start menu
$ pacman -Sy $ pacman -Su Run "MSYS2 MSYS" from Start menu again.
Update the rest of the base packages:
$ pacman -Su - Install build tools & dependencies:
Run "MSYS2 MSYS" from start menu.
Using pacman package manager install required packages:
$ pacman -S --needed base-devel mingw-w64-x86_64-toolchain $ pacman -S git curl $ pacman -S mingw-w64-x86_64-cmake mingw-w64-x86_64-pkgconf mingw-w64-x86_64-zlib mingw-w64-x86_64-libpng mingw-w64-x86_64-libjpeg-turbo mingw-w64-x86_64-freetype mingw-w64-x86_64-fontconfig mingw-w64-x86_64-harfbuzz mingw-w64-x86_64-fribidi mingw-w64-x86_64-zstd To build Qt frontend: $ pacman -S mingw-w64-x86_64-qt5 - Prepare:
Run "MSYS2 MinGW 64-bit" from start menu
$ git clone https://github.com/buggins/coolreader.git $ cd coolreader Since package libunibreak not exists in MSYS2, we must build static version of this library, to do this, we need to call the script thirdparty-deploy.sh to download sources:
$ ./thirdparty-deploy.sh Build system will build static libraries that were not found in the system.
- Compile:
Now we can build program:
$ mkdir qtbuild $ cd qtbuild $ cmake -G "MSYS Makefiles" -D CMAKE_BUILD_TYPE=Release -D GUI=QT5 -D MAX_IMAGE_SCALE_MUL=2 -D DOC_DATA_COMPRESSION_LEVEL=3 -D DOC_BUFFER_SIZE=0x1400000 -D CMAKE_INSTALL_PREFIX=dist .. $ make $ make install Now in qtbuild/dist directory we have CoolReader binary & data.
To add Qt runtime libraries, call:
$ cd dist $ windeployqt --compiler-runtime --no-webkit2 --no-angle --no-opengl-sw --no-quick-import . To add thirdparty runtime libraries, call:
$ cp -pv /mingw64/bin/{libfontconfig-1.dll,libexpat-1.dll,libfreetype-6.dll,libbz2-1.dll,libbrotlidec.dll,libbrotlicommon.dll,libharfbuzz-0.dll,libglib-2.0-0.dll,libintl-8.dll,libiconv-2.dll,libpcre-1.dll,libgraphite2.dll,libpng16-16.dll,zlib1.dll,libfribidi-0.dll,libjpeg-8.dll,libutf8proc.dll,libzstd.dll,libdouble-conversion.dll,libicuin68.dll,libicuuc68.dll,libicudt68.dll,libpcre2-16-0.dll} . After updating any library in MSYS 2, this list may need to be corrected. If after that the program does not start with an error about the missing dll, then you need to copy this library from /mingw64/bin/ to qtbuild/dist.
Using Qt SDK Environment setup:
- Download and install Qt SDK, git, cmake, msys
- Copy contents of git and cmake dirs to QT/mingw/
- Copy make.exe from msys/bin to QT/mingw/bin
Run Qt SDK / Qt Command Prompt. Execute:
> sh > git clone https://github.com/buggins/coolreader.git > cd coolreader > mkdir qtbuild > cd qtbuild > cmake -D GUI=QT -D CMAKE_BUILD_TYPE=Release -G "MSYS Makefiles" -D USE_QT_ZLIB=1 -D CMAKE_INSTALL_PREFIX=dist .. > make > make install cmake -D GUI=QT -D CMAKE_BUILD_TYPE=Release -G "Visual Studio 9 2008" -D USE_QT_ZLIB=1 -D DOC_DATA_COMPRESSION_LEVEL=3 -D DOC_BUFFER_SIZE=0x1500000 -D CMAKE_INSTALL_PREFIX=dist .. cmake -D GUI=QT -D CMAKE_BUILD_TYPE=Release -G "Visual Studio 10" -D USE_QT_ZLIB=1 -D MAX_IMAGE_SCALE_MUL=2 -D DOC_DATA_COMPRESSION_LEVEL=3 -D DOC_BUFFER_SIZE=0x1500000 -D CMAKE_INSTALL_PREFIX=dist .. to disable console, use /SUBSYSTEM:WINDOWS linker option instead of /SUBSYSTEM:CONSOLE
For Qt5, use GUI=QT5 instead of GUI=QT
For building Qt5 app from QtCreator remove -G (generator) parameter:
Release build: -D GUI=QT5 -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=dist .. Debug build: -D GUI=QT5 -D CMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=dist .. It will put built cr3.exe and all necessary distribution files to directory qtbuild/dist.
You need also add following DLLs to this directory in order to get cr3.exe working:
