Duplicate declaration warnings in dashboard

[jhlegarreta]

The Linux Examples Documentation build of the Insight dashboard:
https://open.cdash.org/viewBuildError.php?type=1&buildid=7112107

is signalling duplicate declaration warnings for the classes that are marked as being demonstrated in each example's Documentation.rst file with the .. breathelink:: tag:
e.g.

[CTest: warning matched]
/home/kitware/Dashboards/Tests/ITKExamples-doc-build/ITKEx-buildCore/Common/
BuildAHelloWorldProgram/Documentation.rst:102:
WARNING: Duplicate declaration,
template<typename TPixel, unsigned int VImageDimension = 2> itk::Image :
public itk::ImageBase< VImageDimension >

Not sure why this is being reported. Also, the build seems not to trigger nightly (or it might take a long time to build), and hence the reporting frequency is not consistent.

I think this was resolved meanwhile. Can you confirm Jon?

I think this was resolved meanwhile. Can you confirm Jon?

I am unable to find recent builds in the dashboard, even going a few days back. So I cannot confirm. But if you feel confident that it has been resolved, please close the issue 👍.

Thanks for the effort @dzenanz.

What kind of build are you looking for? Does today's CI build or its dashboard work?

[jhlegarreta]

I was looking at the dashboard regular builds, as the issue report build seemed a regular build that was reporting about the examples documentation builds.

This issue is still observed. Updating to Sphinx 4.4.0 changed the error message slightly:

ITKEx-build/src/Bridge/VtkGlue/ConvertAnitkImageTovtkImageData/Documentation.rst:131: WARNING: Duplicate C++ declaration, also defined at src/Bridge/VtkGlue/ConvertAnRGBitkImageTovtkImageData/Documentation:129.

Please see #324 for additional investigation notes to date. 50 warnings about duplicate declarations in breathelinks are blocking CI from publishing updating docs.

@tbirdso thanks for the detailed investigation!

It sounds like we should exclude the warnings here:

After adding the warning to be excluded in #327 it looks like the build is still failing with CDash warnings 😕

@thewtex @dzenanz Do you have ideas on what I might be doing wrong? It looks like the other warning exclusions in the file were copied from ITK, I'm not sure whether they are being used here.
