Hello,

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

Bug#1069520: sbcl: FTBFS on armhf: make[1]: *** [debian/rules:53: override_dh_auto_build] Error 1

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

Best regards, Peter

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,

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