compile with py3 and Qt5 on Debian Stretch

https://forum.freecadweb.org/viewtopic. ... 90#p274393 helped myself ...

eventually ...

Code: Select all

cmake                                                       \
-DCMAKE_INSTALL_PREFIX:PATH=/opt/local/FreeCAD-0.18         \
-DBUILD_QT5=ON                                              \
-DCMAKE_BUILD_TYPE="DEBUG"                                  \
-DFREECAD_BUILD_DEBIAN=ON                                   \

-DPYTHON_EXECUTABLE="/usr/bin/python3.7"                    \
../freecad

or the whole build script for a Debian Buster scratch install ... https://github.com/berndhahnebach/FreeC ... Qt5_Py3.sh

I'm not really able to solve this Werner ...

I havae problems with Qt5 on Debian Buster ...

Can you try adding -DPYTHON_CONFIG_SUFFIX="-python2.7.x86_64-linux-gnu" to your cmake flags?

This does not work on Python3. Means if I use 3.6 instead of 2.7 the errors do not vanish like for 2.7

Which errors?
Note, that with recent commits from Wednesday it should now work that CMake determines itself the variable PYTHON_CONFIG_SUFFIX. Therefore it reads in Shiboken2Config.cmake which internally sets PYTHON_CONFIG_SUFFIX to an inappropriate value. Afterwards from the given path of the config file CMake searches for further config files which has .cpython<PYTHON_VERSION> in its name and if it has found one it determines the correct value of PYTHON_CONFIG_SUFFIX and then re-reads Shiboken2Config.cmake.

You can check if the procedure succeeded by looking at the CMake output. You should find a line of the form: PYTHON_CONFIG_SUFFIX: ...
git commit 1dded002ca

I can confirm setting (Ubuntu 16.04):

Code: Select all

-DBUILD_QT5=1 -DPYTHON_EXECUTABLE="/usr/bin/python3"

Should suffice (CMake does the rest).

[bernd]

you are right, it is much simpler. On Debian Buster I need with all packages from Debian accept pivy for Py3:

Code: Select all

cmake  -DBUILD_QT5=1  -DPYTHON_EXECUTABLE="/usr/bin/python3"  -DOCCT_CMAKE_FALLBACK=True   ../freecad

I read through this thread now and I'm wondering if it would be possible to create nightly builds for debian testing or unstable with the current set of packaging?
I have pbuilder setup for some packages of mine and could try to integrate a nightly build there.
Or is there already something like this? (not the ubuntu ppa)

[NormandC]

The issue is: where to host them? A properly configured debian repository is needed. The current Releases page on GitHub isn't suited for this.

[reox]

I use reprepro (https://packages.debian.org/stretch/reprepro) for this.
I could build and host them on my machine, but that depends on the traffic.

Isnt it possible to build also debian packages on build.opensuse.org? In this case you could simply build it there. It looks like the appimages are already build there.

Basically it doesn't matter where to host the files. The only important thing is to provide the required directory structure and files. I remember that several years ago someone succeeded to have the repository on dropbox.

[reox]

Dugh... I remembered just now, that I already wrote a script to build the latest freecad version using the stuff from the ppa: https://gist.github.com/reox/522922a1a6 ... edd484f48f
better look on your own gist

I'm currently testing this on my pbuilder machine

edit: But this does not build fully...

I have also not managed to compile freecad in a debited cluster . I have the following errors:

I have already compiled it, my directories were dirty.
