Hi,

During a rebuild of all packages in sid, your package failed to build
on armhf.


Relevant part (hopefully):
The full build log is available from:
http://qa-logs.debian.net/2024/04/20/sbcl_2.3.7-2_unstable-armhf.log

All bugs filed during this archive rebuild are listed at:
https://bugs.debian.org/cgi-bin/pkgreport.cgi?tag=ftbfs-20240420;users=lucas@debian.org
or:
https://udd.debian.org/bugs/?release=na&merged=ign&fnewerval=7&flastmodval=7&fusertag=only&fusertagtag=ftbfs-20240420&fusertaguser=lucas@debian.org&allbugs=1&cseverity=1&ctags=1&caffected=1#results

A list of current common problems and possible solutions is available at
http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute!

If you reassign this bug to another package, please mark it as 'affects'-ing
this package. See https://www.debian.org/Bugs/server-control#affects

If you fail to reproduce this, please provide a build log and diff it with mine
so that we can identify if something relevant changed in the meantime.

This looks a lot like a problem between the `OBSERVED-INTERNAL-REAL-TIME-DELTA-SEC` which is a word and the new 64-bit counters.

❯ git grep observed-internal-real-time-delta-sec
src/code/thread-structs.lisp:  #-64-bit (observed-internal-real-time-delta-sec 0 :type sb-vm:word)
src/code/unix.lisp:                           (sb-thread::thread-observed-internal-real-time-delta-sec thr))

While the current sources still have:

❯ grep -A 2 -B 2 '(tv-sec' crossbuild-runner/backends/arm/stuff-groveled-from-headers.lisp
(define-alien-type nil
  (struct timeval
          (tv-sec (signed 32))
          (tv-usec (signed 32))))
(define-alien-type nil
  (struct timespec
          (tv-sec (signed 32))
          (tv-nsec (signed 32))))

I’m guessing that this is no longer the case on armhf anymore. I’m trying to test this on the porter box abel.debian.org.

Best regards, Peter

Hi,

Tested this and it’s due to the 64t transition. The grovelled data changed:

I honestly don’t understand how to use 64-bit values on this arch, so I created

Hello,

Thanks Peter.  Looks like upstream might be able to commit a fix.
