'make html' error/warning

[Greg Ercolano]

Noticed this today while building the docs:

$ make html
Converting Doxyfile to doxygen version 1.9.8
Generating HTML documentation
/usr/local/src/fltk-1.5.x.git/documentation/src/migration_1_5.dox:110: warning: explicit link request to 'icon() const ' could not be resolved
Built target html

Hi Greg,

thanks for reporting this. It's obviously a bug in your doxygen version (1.9.8). I can reproduce it with this (pretty old) doxygen version as well. The warning erroneously mentions line 110 (instead 106) which is another indication of this buggy doxygen version.

Later doxygen versions (for instance my test version 1.13.2) work fine, hence there's nothing to do on the FLTK side.

    I see, ok.

    I just 'apt install'ed doxygen this morning on a "new" Ubuntu 24.04.3 LTS machine with the latest updates.
    Looks like doxygen 1.9.8 was released Aug 2023.
