Subject: FTBFS for virtuoso-opensource on SPARC
To: debian-sp...@lists.debian.org
Cc: pkg-virtuoso-maintain...@lists.alioth.debian.org
Hi all,
I am the maintainer of virtuoso-opensource[1], a newly packaged
semantic database on which new versions of KDE will depend.
It is therefore important to get it to build on all architectures[2].
I have so far squashed issues on kfreebsd-* and armel but hurd-i386
and sparc are still problematic.
While the hurd-i386 problems are probably too deep right now for a
fix, I believe sparc can be fixed.
I suspect it is a memory alignment issue, similarly to the armel
fix[3], although my attempts at fixing them
similarly[ftbfs-sparc.patch attached] have not been successful yet.
Here's the crash without any patching (full backtrace further below):
Program received signal SIGBUS, Bus error.
sequence_next_inc_1 (name=0x1391148 "RDF_PREF_SEQ", in_map=0,
inc_by=1, err_ret=0x0) at regist.c:714
714 res = (*place);
Location[4].
Here's how to reproduce the crash:
dchroot sid # as needed
dget
http://www.milliways.fr/debian/packages/virtuoso/virtuoso-opensource_6.1.0+dfsg2-2.dsc
dpkg-source -x virtuoso-opensource_6.1.0+dfsg2-2.dsc
cd virtuoso-opensource-6.1.0+dfsg2
# We want to enable debug symbols by adding --with-debug to the ./configure
sed -i 's/\(zlib$\)/\1 --with-debug/' debian/rules
dpkg-buildpackage -us -uc -d
After a while, you should see:
Waiting Virtuoso Server start on port 1111...
Waiting Virtuoso Server start on port 1111...
Waiting Virtuoso Server start on port 1111...
Just Ctrl-C the build. It has already crashed by this point.
Now, to reproduce the crash:
cd binsrc/rdf_mappers
rm vad.db
# This should crash:
../virtuoso/virtuoso-t +wait +foreground +debug +configfile virtuoso.ini
# Now to make it crash again, wipe the database and run it again under gdb:
rm vad.db
gdb --args ../virtuoso/virtuoso-t +wait +foreground +debug +configfile
virtuoso.ini

Note that the build system is quite horrible, but the following
incantation should approximate an incremental compilation for any
edited files under libsrc/Wi/:
$ cd libsrc/Wi/ && make clean && cd ../..
If you have an easy fix for this, I'd be very grateful.
If there's none, I'll escalate to upstream in a few days.
I'm not subscribed to debian-sparc@ but I'm on
pkg-virtuoso-maintainers@ (cc'ed).
Cheers
Arthur
