Hello, Manuel,
In building the tarball from 09/15/2021 and enabling the jvm build, I

$env-get-error-handler is not provided by the JVM runtime.
Disabling the jvm backend results in a successful build.
Thank You,

A possibility to debug such things might be to use the libbacktrace (by
Ian Taylor, also inside GCC)
https://github.com/ianlancetaylor/libbacktrace
This is seems quite interesting but it lacks a little bit of documentation
and examples. I'm not even sure how to get started. Would you have examples?
The GCC compiler (http://gcc.gnu.org/ ....) is using libbacktrace (since
at least GCC 9).
I don't have examples with Bigloo. But the RefPerSys software (symbolic
artificial intelligence system, GPLv3+, for Linux only; see
http://refpersys.org/ for more) is using libbacktrace. The header files
are well written with lots of comments.
You may want to look inside the C++ file
https://github.com/RefPerSys/RefPerSys/blob/master/backtrace_rps.cc
French speaking persons could look talks at
https://afia.asso.fr/journee-hommage-j-pitrat/
And you could be interested in reading Jacques Pitrat's last book:
Artificial Beings, the conscience of a conscious machine. ISBN
978-1-84821-101-8 (published in 2009, Wiley & ISTE).
Jacques Pitrat was not aware of libbacktrace.
I don't know how difficult it would be to patch Bigloo to use
libbacktrace. Potential issues might be related to the garbage collector.
Regards
PS. Offtopic for Bigloo: For people living in Europe, I am seeking
HorizonEurope applications and funding for RefPerSys. Contact me then
