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).
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-10.1 platform.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/falkon
Install falkon by running the following commands:
Unless you have installed both PySide2 and ki18n, remove the translations for the sample hellopython.py script:
rm -rf po/
Fix a missing include in Qt-5.14:
sed -i '/#include <QSettings>/a#include <QFile>' \ src/plugins/VerticalTabs/verticaltabsplugin.cpp
Fix a build problem introduced in Qt-5.15:
sed -i '/#include <QPainter>/a #include <QPainterPath>' \ src/lib/tools/qztools.cpp
Now build the program:
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 the hellopython.py which is in the
scripts/
directory, and perhaps copy
it to your home directory.
-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.
