PDF files missing for HTML output

[hcw70]

Describe the bug I get a lot of reports like Warning: The file /home/hcw/work/Deuta/qdmi/build-x86/doc/qdmi-ref/html/d1/dc2/classqdmi_1_1msg_1_1_msg_router__coll__graph.pdf does not exist, skipping it...

while on the other hand i get such files for latex output:

$ fdfind classqdmi_1_1msg_1_1_msg_router__coll__graph.pdf
doc/qdmi-ref/latex/d1/dc2/classqdmi_1_1msg_1_1_msg_router__coll__graph.pdf

The referenced file shows the inheritance graph for the qdmi::msg::MsgRouter class.

Expected behavior No error message is shown. Looks like the file is generated for latex but not for html. Or the path is wrong.

However, the HTML output is correct, since it references the SVG file.

Version Doxygen version 1.9.1 running on ubuntu linux 22.04 $ pkg -l doxygen

The 1.9.1 version is from January 8, 2021, what happens when using the current doxygen version 1.9.6?

edit are you building also CHM of QHP?

Furthermore:

• Can you please attach a, small, self contained example (source+configuration file in a, compressed, tar or zip file) that allows us to reproduce the problem? Please don't add external links as they might not be persistent.

Can confirm that it is still present in 1.9.8 (0ea6a2376f93d1bde432429f58666884e018a07a*)
Additional information:

• GENERATE_QHP = YES
• Setting QHG_LOCATION = qhelpgenerator produces the warning

qhelpgenerator seems rather old: Qt Help Generator Version 1.0 (Qt 4.8.7) although Qt is installed in versions 6.5.0 and 5.15.9 (Fedora 38)

Attached a small example. Archiv.zip

Probably for this issue there is already a proposed PR #8770

[albert-github]

I've just checked the PR #8770 (and resolved the conflicts) and this solves the issue as mentioned in https://github.com/doxygen/doxygen/issues/9966#issuecomment-1564349853

OK, I'll give it a try as soon as the PR is merged.
