Setting up out-of-tree build &amp; SofaPython 3 plugin

Blocked

Hi,

I have been using SOFA for the last half year and would like to start using the Python3 integration as it has a lot of interesting new features: https://github.com/SofaDefrost/plugin.SofaPython3

In the link, they recommend using an out-of-tree build if you want to maintain the possibility of using SofaPython plugin (the regular Python2 plugin). I have spent a significant amount of time trying to understand and implement an out-of-tree build, but am having some difficulty with it. Is there someone who could provide me with an easy-to-follow step-by-step process for this?

However, I went instead and did cmake and build without SofaPython plugin, but was faced with the error that I hadn’t set SOFA_ROOT when trying to import Sofa. I hence set SOFA_ROOT in my zshrc/bashrc file to [HOME_DIR]/dev/sofa/build/master but to no avail. I managed to successfully do import Sofa when adding the path [HOME_DIR]/dev/sofa/build/master/lib to PYTHONPATH in zshrc/bashrc file, but it gave the error ‘No module named Sofa.Helper’

Given my limited background in developing applications, it would be great to have some guidance on this. Thank you very much and I really appreciate the help

Hi @stonkens,

You can have a look at this thread, it should help you to set things right.

Let me know if you still have problem after this.

Hi @jnbrunet,

Thank you very much for the detailed information. I have some errors, unfortunately. After git pull from master and adding the plugins I want (SoftRobots, ModelOrderReduction, STLIB, note that SoftRobots requires SofaPython) I got the following errors when building (running ninja command):
/usr/bin/ld: cannot find -lSofaComponentCommon
collect2: error: ld returned 1 exit status

I assume this is due to some mismatch between the Sofa versions –> Is there a way to use a released build of Sofa instead of pulling from master?

I also tried building without the test scripts (GTestMain etc.) but this gives error when running ninja on the SofaPython3 plugin (Step 2).

Hey @stonkens,

Unfortunetly, the SofaPython3 plugin is following closely the master branch as it does not had an official release yet.

However, for this particular problem you have, it looks quite close to this thread.

You can deactivate the build of tests on SofaPython3 by setting the cmake variable SP3_BUILD_TEST=OFF.

Hey @jnbrunet,

Thanks again for helping out. I am getting a better understanding of the inner workings, but still require some help unfortunately.

I am now at status with origin master branches for SoftRobots, Sofa, SofaPython3. I have successfully run build and complete Step 1.

For step 2 when configuring SofaPython3 I get the following error:
CMake Error at /home/stonkens/dev/sofa/build/install/lib/cmake/SofaGui/SofaGuiConfig.cmake:43 (find_package):
  Found package configuration file:

    /home/stonkens/dev/sofa/build/install/lib/cmake/SofaMisc/SofaMiscConfig.cmake

  but it set SofaMisc_FOUND to FALSE so package "SofaMisc" is considered to
  be NOT FOUND.  Reason given by package:

  The following imported targets are referenced, but are missing:
  SofaNonUniformFem

Call Stack (most recent call first):
  bindings/SofaGui/CMakeLists.txt:15 (find_package)

I checked and SofaNonUniformFEM is in the plugins within $SOFA_BLD/install.
I have checked both the sofa forum and the issues on github but have not found a similar issue unfortunately.

I’m happy to email instead (given this seems to be an issue that only I am having), which may allow for a bit faster debugging.

EDIT: What might help, I get this warning when configuring in step 1 of your first linked post (building dev version of Sofa):

CMake Deprecation Warning at SofaAdvanced/CMakeLists.txt:15 (message):
   SofaAdvanced is deprecated.
   You should now explicitely find (find_package) and link (target_link_library) each module you need within: 
   SofaNonUniformFem

Hey @stonkens,

You are not the only one having this issue, it seems I also have it. Looks to be caused by a recent change merged yesterday in the master branch of SOFA.

SOFA has been undergoing a lot of refactoring these past weeks, its compilation and the one of the plugins are a little bit unstable at the moment.

I’ll look into it and and update this thread once I’ve made a PR fixing it (probably tomorrow).

Pull request is here.

We need to wait for the tests to pass and a review before merging the fix, but you can already checkout the PR’s branch. SofaPython3’s master branch should compile correctly with this fix on SOFA.

Thank you very much @jnbrunet.

Final question, splib (part of STLIB: Sofa Template library) has less functionality in SofaPython3. Is this done intentionally? Particularly, I rely on Vec3 and Quat classes –> I have found a workaround so definitely no need to resolve this, but was wondering what the underlying reason was.

Cheers,

Sander

Hey @stonkens,

I haven’t worked with STLIB, therefore I cannot really say what have or have not been migrated from SofaPython to SofaPython3.

For these particular types, it seems there are some bindings in the SofaTypes modules.

There is not so much documentation on those classes, but I guess you can easily infer their functionalities from their method names and arguments.

Hope that helps !

Hey @stonkens,

regarding your questions about splib (and STLIB): SPLIB basically has to be ported to python 3. For now SofaPython3’s functionality is mostly related to the bindings and scripting. We are slowly populating SPLIB with the functionality it had before. SPLIB is now a part of SP3 and there could eventually be a separate STLIB for python 3 to complement the SoftRobots plugin.

In any case, I think porting the code from the old STLIB (which includes SPLIB) should not be soo difficult. If you happen to do some porting for SPLIB, you can even create a pull-request!

Cheers

Stefan

Thank you very much @jnbrunet and @secaida, this is all very helpful.

I will definitely make a PR if I port code to py3.

Hi @nguyenvanpho,

Could you try to update both your SOFA and SofaPython3 source code from their respective master branches (i.e. git checkout master && git pull). Try cleaning any previous builds from both of them (i.e. rm -rf build/*) and restart the compilations and installations (ninja install).

That’s the inconvenient of following so closely a development branch, there are often bug introduced! This problem was introduced recently (last week) in SOFA and makes external plugins fail to find the modules of SOFA.

There’s a fix being made right now in SOFA, see this pull request. Hopefully it should be merged during our next SOFA developer meeting, next Wednesday. If you cannot wait until then, you can try to checkout the fix branch (in SOFA, not SP3):

git remote add fredroy https://github.com/fredroy/sofa.git
git fetch fredroy
git checkout -b fix_outoftree_compil

Sorry for this. We are working hard right now to make SOFA and SP3 stable and release a first version very soon.

My bad, the fix was in SOFA, not SP3. Hence got to your SOFA repository and do the git pull there.

Also, make sure your SP3 origin is the one from sofa-framework, and not SofaDefrost, ie:


$ cd $SP3_SRC
$ git remote -vv
(..)
origin git@github.com:sofa-framework/plugin.SofaPython3.git
(..)
