On attempting to update wxmaxima, there is a build problem, with many messages like:
In file included from /home/james/.cache/yay/wxmaxima-git/src/wxmaxima/src/main.cpp:49:
/home/james/.cache/yay/wxmaxima-git/src/wxmaxima/build/addprivatefonts.h: In function ‘void addprivatefonts()’:
/home/james/.cache/yay/wxmaxima-git/src/wxmaxima/build/addprivatefonts.h:7:91: error: ‘AddPrivateFont’ is not a member of ‘wxFont’
7 | if (wxFileExists("/usr/share/wxMaxima/fonts/LibertinusKeyboard-Regular.otf")) wxFont::AddPrivateFont("/usr/share/wxMaxima/fonts/LibertinusKeyboard-Regular.otf");
| ^~~~~~~~~~~~~~
This is (I think) not connected to this issue: Meeting wxwidgets and wxwidgets-common requirements is suddenly complicated - #4 by outsidefactor as the reason that there was a new package is that the AUR maintainer of wxmaxima acted with commendable celerity in updating his package.
I have also reported this on AUR but thought it worthwhile adding a note here both as a heads-up and also in case (unlikely I think) that it is in fact a Manjaro-specific problem.
