Hi,
I'm trying to build Boost.GIL documentation with Sphinx,
using also Breathe and Exhale extensions.
The whole toolchain runs Sphinx, which runs Exhale, which runs Doxygen to
generete XML.
Doxygen and Exhale seems fine, as I can see this logged:
```
[+] Exhale: doxygen ran successfully in 11.75 seconds.
[~] Exhale: adding tree view css / javascript.
[+] Exhale: added tree view css / javascript.
[~] Exhale: parsing Doxygen XML.
[+] Exhale: finished parsing Doxygen XML in 35.71 seconds.
[~] Exhale: generating reStructuredText documents.
...
[+] Exhale: generated reStructuredText documents in 23.86 seconds.
```
Next, Sphinx is taking over
```
building [html]: targets for 4515 source files that are out of date
...
```
Sphinx fails with a very long list of warnings like
```
WARNING: Error when parsing function declaration.
WARNING: Duplicate explicit target name
WARNING: Duplicate ID
WARNING: Duplicate declaration.
WARNING: doxygenfunction: Unable to resolve multiple matches for function
...
```
Eventually failing with
```
Exception occurred:
File
"/mnt/d/boost.wsl/libs/gil/.venv/lib/python3.6/site-packages/sphinx/domains/cpp.py",
line 635, in <lambda>
return self._stringify(lambda ast: ast.get_display_string())
AttributeError: 'str' object has no attribute 'get_display_string'
```
I'm not very experienced with Sphinx and I find it difficult to figure out
where is the problem.
Am I doing anything wrong or would this qualify as bug report for
https://github.com/sphinx-doc/sphinx
Here I posted complete story with all logs
https://gist.github.com/mloskot/ad6f79b9c5fd15027467e9a55429b52e
and pointer to Git branch with Sphinx config
