Picongpu: sphinx documentation broken

If I try to build our documentation on the latest dev * e988152 (HEAD -> dev) Merge pull request #2559 from ax3l/doc-energyFields I got the following issues.

$ doxygen

I see the same errors but they are just warnings in sphinx.

Yes, same above in the original report. That means you do not see build errors and this issue is outdated ;) Some terminals just mark the lines "WARNING: ..." red since it also contains the keyword "error" at some point. But breathe/sphinx still consumes (ignores) those and builds.

Can we close?
Most warnings are just doxygen issues with modern C++, where we can just wait and update over time. Others are macro hacks that we should clean up or exclude in-code.

All requirements are documented here for install with pip install -r docs/requirements.txt and otherwise please open a new issue. Yet I think #2383 is the place to go for such warnings.
https://github.com/ComputationalRadiationPhysics/picongpu/blob/dev/docs/requirements.txt
https://github.com/ComputationalRadiationPhysics/picongpu/blob/dev/.readthedocs.yml

Here is the documentation in our documentation how to build our documentation:

What version of Doxygen are you using? It's Doxygen originated.

It builds on readthedocs with ...:
https://readthedocs.org/projects/picongpu/builds/6963275/

And also locally for me with 1.8.13.

ax3l picture ax3l on 29 Mar 2018

Doxygen is version 1.8.11

The Doxygen parser/translation errors you are seeing are only warnings for sphinx. Are you sure your build does not complete?

(See message: "WARNING" error in doxygen...)

Does your make html end in:
```
copying images... [100%] install/libraryDependencies.png
copying static files... done
copying extra files... done
dumping search index in English (code: en) ... done
dumping object inventory... done
build succeeded, 156 warnings.

Build finished. The HTML pages are in build/html.

@psychocoderHPC did we fix your local setup offline last time?

I see the same errors but they are just warnings in sphinx.
The documentation builds fine.
I used:

  • Darwin Kernel Version 18.7.0 (MacOS 10.14.6)
  • sphinx-build 2.0.1
  • doxygen 1.8.14

The following output is shown (please excise the German output setting in sphinx):

I see the same errors but they are just warnings in sphinx.

Yes, same above in the original report. That means you do not see build errors and this issue is outdated ;) Some terminals just mark the lines "WARNING: ..." red since it also contains the keyword "error" at some point. But breathe/sphinx still consumes (ignores) those and builds.

Can we close?
Most warnings are just doxygen issues with modern C++, where we can just wait and update over time. Others are macro hacks that we should clean up or exclude in-code.

All requirements are documented here for install with pip install -r docs/requirements.txt and otherwise please open a new issue. Yet I think #2383 is the place to go for such warnings.
https://github.com/ComputationalRadiationPhysics/picongpu/blob/dev/docs/requirements.txt
https://github.com/ComputationalRadiationPhysics/picongpu/blob/dev/.readthedocs.yml

Here is the documentation in our documentation how to build our documentation:

I am totally fine with closing this issue since describes only warnings.
