QtPdf binaries are provided via Marketplace for convenience; but you can also build it yourself.
Building the 5.15 version
- sources for QtPdf module are hosted within QtWebEngine repository. Let's clone and initialize the git repository:
$ git clone https://code.qt.io/qt/qtwebengine.git $ cd qtwebengine $ git checkout 5.15 $ git submodule update --init --recursive $ cd ..
- fortunately build of QtWebEngine itself is not necessary for QtPdf build; therefore let's configure shadow build with:
$ mkdir build $ cd build $ qmake ../qtwebengine -- -no-build-qtwebengine-core
- you should see configuration summary after previous step:
Configure summary: Qt WebEngine Build Tools: Use System Ninja ....................... yes Use System Gn .......................... no Jumbo Build Merge Limit ................ 8 Developer build ........................ no QtWebEngine required system libraries: fontconfig ........................... yes dbus ................................. yes nss .................................. yes khr .................................. yes glibc ................................ yes QtWebEngine required system libraries for qpa-xcb: x11 .................................. yes libdrm ............................... yes xcomposite ........................... yes xcursor .............................. yes xi ................................... yes xtst ................................. yes Optional system libraries used: re2 .................................. yes icu .................................. no libwebp, libwebpmux and libwebpdemux . yes opus ................................. yes ffmpeg ............................... no libvpx ............................... yes snappy ............................... yes glib ................................. yes zlib ................................. yes minizip .............................. yes libevent ............................. yes jsoncpp .............................. yes protobuf ............................. yes libxml2 and libxslt .................. yes lcms2 ................................ yes png .................................. yes JPEG ................................. yes harfbuzz ............................. yes freetype ............................. yes xkbcommon ............................ yes Qt PDF: Support V8 ............................. no Support XFA ............................ no Support XFA-BMP ........................ no Support XFA-GIF ........................ no Support XFA-PNG ........................ no Support XFA-TIFF ....................... no Qt PDF Widgets: Support Qt PDF Widgets ................. yes Note: QtWebEngine build is disabled by user. Note: The following modules are not being compiled in this configuration: webenginecore webengine webenginewidgets Qt is now configured for building. Just run 'make'. Once everything is built, you must run 'make install'. Qt will be installed into '/usr'.
- QtPdf build will use gn and ninja to build Pdfium which is required for the QtPdf module. Let's perform the build:
$ NINJAJOBS=-j4 make -j4 && make install
Building the 6.3 version
- sources for QtPdf module are hosted within QtWebEngine repository. Let's clone and initialize the git repository:
$ git clone https://code.qt.io/qt/qtwebengine.git $ cd qtwebengine $ git checkout 6.3 $ git submodule update --init --recursive $ cd ..
- configure shadow build with:
$ mkdir build $ cd build $ qt-configure-module ../qtwebengine -- -DFEATURE_qtwebengine_build=OFF
- build the pdf
$ cmake --build . --parallel
Since QtPdf comes with Qml and Widget APIs examples using those can be found in examples/pdf and examples/pdfwidgets.
In case of any issues please open bug report for PDF component in https://bugreports.qt.io/.
Historical repository
The older version in the Qt Labs QtPDF repository still exists, but development now continues in the qtwebengine repository. This was prompted mainly by the upstream Chromium switch of build system from gyp to gn: it was some work to get qtwebengine building with that. Chromium (and thus Qt WebEngine) includes PDFium already; so it was easier to build QtPDF from there than to fix the build in the other repository.
