Building FPC 3.2.2 on Debian "Testing" (Bookworm) x86_64
MarkMLl:
I've been rebuilding my main system from Debian "Buster" to "Bookworm" since I need it to be pretty close to the bleeding edge for some stuff that I might need to build manually.
An existing FPC 3.2.2 runs OK on this, as does current Lazarus etc. and various application software built using it subject to a symlink issue I've mentioned elsewhere.
I can rebuild FPC 3.2.2 using 3.0.4 on a different system based on Debian 11 ("Bullseye") without problem.
If I try rebuilding 3.2.2 using 3.0.4 on the new system ("Bookworm") I get a failure, which appears to boil down to

So far I've had no success trying to get a backtrace

I'll try working through other versions on the same system, but think I'm out of my depth.
Later: on the "Bullseye" system I can build 2.6.4 using an existing 2.6.4. On the new "Bookworm" system that fails in a way similar to that described above. I assume intervening versions behave similarly.

MarkMLl:
Does anybody have any thoughts on this? Trying to look at it (with my very imperfect recollection of gdb) it appears that the problem is before I have any chance of setting a breakpoint etc.

Hello Mark.
In my Bullseye system, I can build fpc 3.2.2, 3.2.3 and 3.3.1 with the "classical" script and fpc 3.2.0 or 3.2.2 compiler:
--- Code: Bash [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---COMPILER=fpcmake cleanmake all FPC=$COMPILER OPT="-Fl/usr/local/lib" make FPC=$COMPILER install INSTALL_PREFIX=/usr/
But I did not try yet to build fpc 2.6.4. nor install last unstable Debian Bookworm.
Did you try to build fpc 3.2.2 using fpc 3.2.0 on Debian Bookworm?
Also do you have a idea of what difference between Bullseye vs Bookworm that could explain the fail of compilation?

Bullseye is no problem at all, I can definitely build 3.2.2 and 2.6.4 so presume that the intervening versions are also OK.
The error as described was using 3.0.4 as the starting compiler, which I thought was SOP. If I switch to using 3.2.0 to build 3.2.2 things appear to progress further... I'll update this in a few minutes but want to post early in case anybody else is scratching their head.

Ho, many thanks to be the explorer and save us a lot of hair, I will deeply study your result (and then maybe install Bookworm for testing).
