Federico and all,
I've found a better solution for this issue (a little late, but better
than never). If you use the latest version of castxml, the massive error
problem is solved. Here's the steps:
1) Download the latest pre-built version of castxml at:
https://github.com/CastXML/CastXMLSuperbuild/releases
For Ubuntu 24.04, I used:
https://github.com/CastXML/CastXMLSuperbuild/releases/download/v2025.09.03/castxml-ubuntu-24.04-x86_64.tar.gz
2) Install the tar.gz file into any directory.
3) Set a path to the newly installed castxml binary. For example, I
installed into /media/re/nvme/castxml:
export PATH=/media/re/nvme/castxml/bin:$PATH
gr_modtool bind now works good.

Hi,
Thanks (publicly) to Ron for his solution, it worked like a charm. For
anyone finding a similar problem, I've used a Docker with a 22.04
Ubuntu (you may use mine at
https://github.com/git-artes/docker-gnuradio/, although there are
several other out there), migrated the OOT through the required
gr_modtool bind, and it also worked perfectly in my "native" 24.04.

I just tried gr_modtool bind on Ubuntu 24.04, and I'm getting the
same
results (huge error dump).
For the last OOT I updated to 3.10, I just went back to Ubuntu
20.04 and
gcc 9.4.0. Then I checked that it builds okay on Ubuntu 24.04.
I've pasted my Ubuntu 24.04 gr_modtool bind error dump onto the
end of
this e-mail.
