Not sure the pypi package is maintained.

The problem isn't compiling so much as it is running the system.

are you configuring pivy with setup.py or with cmake?

Yup, same bug. I've seen him haunting the same places as me

I think I've tried both. Which should I be using?

Cmake is preferred. But actually both should work.

If I read the link I posted correctly you need to delete the old _coin.so. And run the compilation again. There is also the chance you have multiple _coin.so libraries. Can you post the output of this:

Code: Select all

sudo updatedb
locate _coin.so

sudo updatedb
chris@shop:~/github/pivy$ locate _coin.so
/usr/lib/python3/dist-packages/pivy/_coin.so

I checked the date, and it's older than my last setup.py which was last night.

After building with cmake

Code: Select all

sudo updatedb
chris@shop:~/github/pivy/build$ locate _coin.so
/home/chris/github/pivy/build/interfaces/_coin.so
/usr/lib/python3/dist-packages/pivy/_coin.so

so It made a difference and the date is current.

Made no difference, crash in same place.

what does this command reports:

Code: Select all

apt list pythoon3-pivy

I suspect that you have pivy installed via the package-manager but want to replace it with a self compiled version. The version from the package-manager doesn't have the SoGeo bindings. (it's version 0.6.5)

Some replaced the important files manually, and I guess this worked.

So I've tried using synaptic complete removal of pivy.so and soqt.so, and even went so far as to remove the directories

Code: Select all

/usr/lib/python3/dist-packages$ sudo rm -rf pivy

I then in the pivy/build directory did

Code: Select all

cmake ..
make 
sudo make install

and it seemed to install to Installing: /usr/lib/python3/dist-packages/pivy/
On running freecad (after making it)

Code: Select all

reeCAD: /home/chris/github/freecad-source/src/Mod/Part/Gui/TaskDimension.cpp:1343: static void PartGui::ArcEngine::initClass(): Assertion `SoEngine::getClassTypeId() != SoType::badType()' failed.
/home/chris/bin/freecad: line 2: 89991 Aborted                 (core dumped) bin/FreeCAD

I've tried recompiling fresh from @realthunder's coin, and fresh from the original coin3d coin.
In every case I'm getting the same crash.

so I'm obviously missing a step here.

I'm sorry to be such a newb, but how would you take a fresh linux install, and install and build freecad from source? I can't seem to do it anymore.
