Description Jens Radloff 2024-12-14 11:21:23 UTC

1. Set local git repository to Falkon in version 24.12.0:

----------

<User name>@<Hostname>:/opt/falkon/falkon$ git reset --hard  v24.12.0
HEAD is now at b0a6e7a68 GIT_SILENT Sync po/docbooks with svn
<User name>@<Hostname>:/opt/falkon/falkon$

----------


2. Several symlinks have to be defined in order to fix several "not found" compilation errors:

----------

# cd /usr/lib/
# mkdir bin
# cd bin
# ln -s /usr/bin/shiboken6
# ls -ahl shiboken6
lrwxrwxrwx 1 root root 18 Dez 13 18:21 shiboken6 -> /usr/bin/shiboken6

# cd /usr/lib
# mkdir include
# cd include
# ln -s /usr/include/PySide6
# ls -ahl PySide6
lrwxrwxrwx 1 root root 20 Dez 13 18:30 PySide6 -> /usr/include/PySide6

root@<Hostname>:/usr/share/PySide6/doc# ls -ahl qtwebenginecore.rst
lrwxrwxrwx 1 root root 64 Dez 13 21:19 qtwebenginecore.rst -> /usr/share/doc/python-pyside6-doc/doc/extras/QtWebEngineCore.rst

----------


3. Configure compilation process with the following command in the build folder:

$ cmake .. --fresh --install-prefix=$FALKON_PATH_IN_OPT -D BUILD_PYTHON_SUPPORT=ON -DCMAKE_BUILD_TYPE=Debug -Wno-dev


4. This is the result of the configure process (partial quote from it):

Comment 1 Juraj 2024-12-14 13:15:23 UTC

Hello,

I remember having similar problem with some Pyside6/shiboken6 version on Artix (or KDE Neon) as well, where the package did not contain the required files.
It was fixed upstram (in Qt) as far as I know.

Not a Falkon error.

Best regards,
Juraj
