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).

本パッケージは LFS-9.1 において正しくビルドでき動作することが確認されています。

Installation of 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>' \

Now build the program:

mkdir build &&
cd    build &&

      -DCMAKE_BUILD_TYPE=Release  \
      .. &&


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.

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.
