Created attachment 215289 [details] Build log
On 2 computers I use (pure ~x86), immediately after the line ;Wrote bootstrapping image: #P"/var/tmp/portage/dev-lisp/clozurecl-1.4/work/ccl/x86-boot32" I have: ;Wrote heap image: #P"/var/tmp/portage/dev-lisp/clozurecl-1.4/work/ccl/lx86cl.image" >>> Source compiled. >>> Test phase [not enabled]: dev-lisp/clozurecl-1.4 >>> Install clozurecl-1.4 into /var/tmp/portage/dev-lisp/clozurecl-1.4/image/ category dev-lisp >>> Completed installing clozurecl-1.4 into /var/tmp/portage/dev-lisp/clozurecl-1.4/image/ And you have instead: > Error: Errors (:SIGNALED 6) reloading boot image: > ;Loading level-1.lx32fsl etc. What can be the difference? My emerge --info is very similar to yours. The first difference is the processor: my laptop has pentium-m, my desktop has celeron. Maybe, the ccl binary does not like amd? (this would be a pity). Another difference is the kernel. My laptop runs 2.6.31-tuxonice, and desktop 2.6.32-gentoo. Both with "Disable heap randomization" - lisps often dislike randomization, non-executable stack and heap, and other security measures. Does your kernel have any of these security features enabled? Several users reported that they use clozurecl successfully. So, it does not fail for everybody. We have to identify the difference.
I have heap randomization turned on, that might be the first problem. But the tinderbox has *everything* in the tree merged in so you might want to look at possible automagic dependencies as well.
(In reply to comment #3) > I have heap randomization turned on, that might be the first problem. > > But the tinderbox has *everything* in the tree merged in so you might want to > look at possible automagic dependencies as well. > I can't reproduce this. Automagic dependencies? From what I've seen nothing from autotools is used, and nothing that seems like an automagic dep either. I think grozin's approach is the right one, I haven't checked my kernel configuration yet.

My guess is that you've compiled the tinderbox kernel wit CONFIG_COMPAT_BRK=n Clozure needs that
Good guess, Stelian. I don't have that enabled at all. But I don't see any particular check for that in the ebuild? I'm pretty sure another lisp ebuild has a check for brk settings…
dev-lisp/sbcl only checks that sys-devel/gcc wasn't compiled with +hardened, nothing more. I wouldn't know how to check for CONFIG_COMPAT_BRK=y other than grepping /proc/config.gz but not everyone enables that(CONFIG_IKCONFIG). Suggestions ?
It seems unlikely that some installed package can interfere with building clozurecl. The tarball contains a binary lisp compiler; it is used to re-build clozurecl from sources on the user's computer. No make, autoconf, ... I make the following experiment: prepended strace -ff -o log before the line ./${CCL_RUNTIME} -n -b -Q -e '(ccl:rebuild-ccl :full t)' -e '(ccl:quit)' in the ebuild. I got 95 log.* files. The process which writes the messages ;Wrote bootstrapping image: #P"/var/tmp/portage/dev-lisp/clozurecl-1.4/work/ccl/x86-boot32" ;Wrote heap image: #P"/var/tmp/portage/dev-lisp/clozurecl-1.4/work/ccl/lx86cl.image" has the minimum pid. You have the first message, but not the second one - you get an error message instead. The strace log for this pid (near the end) looks like write(1, "recl-1.4/work/ccl/x86-boot32\"", 29) = 29 then the messages nanosleep({0, 330000000}, 0xbfc832a0) = 0 gettimeofday({1263506318, 449900}, NULL) = 0 are repeated many times, then nanosleep({0, 330000000}, {0, 281706597}) = ?

On your computer lx86cl.image has not been written, right? Then, if you do a similar experiment, we can find where the difference in behaviour starts. And, maybe, we can identify which kernel feature (if any) is responsible for the difference.
Is this still valid with 1.10?
