Interrogate: Unrecognized option '-nomangle'

[DrLuke]

When building the C++ files during setup, interrogate fails because of an unrecognized argument.

python setup.py                                                                                                                                                                            [1]

The C++ modules of the pipeline are faster and produce better 
results, but we will have to compile them. As alternative, 
a Python fallback is used, which is slower and produces worse 
results. Also some plugins only partially work with the python 
fallback (e.g. PSSM). Do you want to compile the C++ modules? (y/n): y

It seems the setup failed, do you want to open the troubleshooting page for this step? (y/n): ```

[rdb]

You need to use a recent development build of Panda3D in order to use the RenderPipeline.

[DrLuke]

Do you mean a build that comes with the headers? The package I installed it from also installs headers. I'm running on Arch Linux and have version 1.9.4 of panda installed, which seems to be the newest.

[rdb]

No, by development build I mean one that is built from the master branch on GitHub, which will be a pre-release of 1.10. The latest stable release (1.9.4) is too old for the RenderPipeline.

If you don't want to build Panda from source then you can install it with pip:

sudo pip install --pre --extra-index-url https://archive.panda3d.org/ panda3d

(It may be advisable to create a virtualenv instead of doing a system-wide install, if you so prefer.)
