Build errors

[beichun]

Hi,
I'm building the plugin on Ubuntu 18.04 with python3.7.9, following this link: https://sofapython3.readthedocs.io/en/latest/menu/install.html.
When running make, I get the following error:
(1) serveral ones about getPathName():

By the way, I was able to build sofa without problems.
Any help is appreciated!

Hi,

I am having the same issue building on Windows. Anyone got a fix for this?

Thanks,

Ben

I tried building it again following this and the error is gone. Need to be careful to pull the master branch for Sofa instead of v20.06(and so on).

Hey @beichun and @benjamin-m-jackson ,

We have recently fixed many things with SofaPython3. Could you update the source of the plugin with the master branch of SofaPython3 and try again?

@jnbrunet Thanks for the reply. The latest version works nicely. It took me some time to find out that I need to export SOFA_ROOT before I can run sofa from python interpreter.
By the way, is there a full documentation of SofaPython3? I read the examples and doc in the repo but I think there are lots of features not included.

Hey @beichun ,

Yeah, it isn't very easy right now to set all of this up.

We are working on improving this before the first stable release (which should happen before the end of this month). @hugtalbot has already started improving the examples here (which should be merged this week). We will also re-work the documentation so that every steps to get SP3 running are detailed and friendly.
