FreeCAD from conda forge

[bernd]

installed FreeCAD from conda-forge in my miniconda on Windows (https://anaconda.org/conda-forge/freecad) It does not show the commit number, but after playing a bit I found quit fast the package is outdated. On https://anaconda.org/conda-forge/freecad I found the package was updated 6 month ago.

Is this maintained by someone from the forum here?

no this is maintained by me, but I haven't updated the freecad-package on conda-forge for a while. The weekly builds go into the freecad/label/dev channel [1]. You can add this channel temporary by adding "-c freecad/label/dev" to the create/install command or add it directly to the ~/condarc file by eg "conda config --add channels freecad/label/dev".

Currently conda-forge is a bit broken for us as they forced us to use compilers provided by anaconda and added quite some additional changes which makes it very hard to compile c++ sources (especially with cmake, see for example smesh which I am currently fighting with: [2]). But using some older packages (channel= conda-forge/label/cf201901) allows to still build freecad with the old tools. So it's best to use "conda-forge/label/cf201901" instead of "conda-forge" channel. Again this channel should be listed in .condarc or used as argument for the install/create commands.

Is there a list of the needed channels for FreeCAD somewhere, or do I need to go package by package find the channel and add it?

Necessary channels for weekly builds are:

-freecad/label/dev
-conda-forge
-defaults

This is how the channels should be listed in the .condarc file. The order is important. If you have only conda-forge and defaults in the .condarc install/create/update via

Code: Select all

conda install/create/update ... -c freecad/label/dev

is equivalent.

If you install packages in an environment things get pinned (I am not sure how this works). So this adds some constraints to the packaging solver. In your case I would try to create a new environment which doesn't have any constraints and will look for the the most recent dependency-tree.

So it's best if you try:

Code: Select all

conda create -n <name> freecad -c freecad/label/dev

For more information you can have a look how we create the appimage with additional dependencies like (pandas, scipy, sympy,...):

FreeCAD should be 0.19.17175 I think? How do I get QT 5.9?

There are some dependency solver flags which have some influence on the result. Normally conda should find the qt5.9 based dependency tree. https://www.anaconda.com/understanding- ... rformance/

Also updating conda in the base directory makes sense.

If this all doesn't work you can always enforce version by specification:

Code: Select all

conda create -n <name> <package> qt=5.9.*

This works also with update and install command.

I force installed qt 5.9 into the env and everything now works.

When trying to use this env for the dependencies I'm getting a bunch of boost linking errors.
Where is the recipe used to build the weekly builds?
Do I need to set something for C++17, I saw some stuff in other threads but I don't know the final solution used.

EDIT: I also have this https://forum.freecadweb.org/viewtopic. ... 30#p315850

Most likely you need to set:
-D Boost_NO_BOOST_CMAKE:BOOL=ON

Else cmake uses the cmake config from boost which is quite different.

Recipe I currently use for qt5.9 boost 1 70 is the master branch here:
