Falkon-22.12.2
Introduction to falkon
Falkon is a KDE web browser using the QtWebEngine rendering engine. It was previously known as QupZilla. It aims to be a lightweight web browser available through all major platforms.
Although falkon is now part of KDE, it can be installed without KDE (with the loss of kwallet functionality).

Warning
Falkon relies on QtWebEngine. That uses a forked copy of chromium, and is therefore vulnerable to many issues found there. The Qt developers have always preferred to make releases at the same time as the rest of Qt (rather than adding emergency fixes). Now that they are keen to move to Qt6, the 5.15.3 and later Qt-5.15 releases are initially only available to paying customers. QtWebEngine is something of an exception because of its LGPL licence, but getting the git sources (with the forked chromium submodule) to a point where they will successfully build on a current BLFS system can take a lot of effort. Be aware that future fixes for vulnerabilities might be very delayed, to the extent that you might wish to consider using a different browser.
This package is known to build and work properly using an LFS 11.3 platform.

falkon Dependencies
Required
extra-cmake-modules-5.103.0, KDE Frameworks-5.103.0 (for karchive), and qtwebengine-5.15.12
![[Note]](../images/note.png)
Note
Strictly speaking, only karchive is required to build falkon, but several other packages in KF5 can be used if they are present. To build only karchive, download that package from the directory specified in KDE Frameworks-5.103.0 and use the build instructions on that page changing the $KF5_PREFIX to /usr.
Optional
gnome-keyring-42.1, PySide2, and Shiboken2

Installation of falkon
Install falkon by running the following commands:
mkdir build &&
cd build &&
cmake -DCMAKE_INSTALL_PREFIX=/usr \
-DCMAKE_BUILD_TYPE=Release \
.. &&
make
To test the results, issue: make test. All
tests should pass. If any fail, the full results will be in
Testing/Temporary/LastTest.log.
Now, as the root user:
make install
If you have installed Pyside2 you will want to
examine hellopython.py which is in the scripts/ directory, and perhaps copy it to
your home directory.
Command Explanations
-DBUILD_TESTING=OFF: This will save a little time and space by
not building the test programs, use this if you do not wish to run the test.
