Fail to compile on SPARC Linux

Sat Mar 20 23:24:46 UTC 2010

Hi all,

I am the maintainer of the Virtuoso package at Debian[1]. Virtuoso is
important to us because we strive to have package working on all our
supported architectures and Virtuoso is a dependency of recommended features
of newer versions of KDE.
I am working hard to make sure that Virtuoso compiles and works properly on
all platforms.
I have so far squashed porting issues on FreeBSD kernel and ARM of Debian
but SPARC is still problematic[2].

I suspect it is a memory alignment issue, similarly to the ARM 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].

Note that I compile with the --with-debug/ configure flag.

After compiling for a while, I see:
Waiting Virtuoso Server start on port 1111...
Waiting Virtuoso Server start on port 1111...
Waiting Virtuoso Server start on port 1111...
At this point, I just Ctrl-C the build. It has already crashed.

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

By the way, my incantation for an incremental compilation for any edited
files under libsrc/Wi/:
$ cd libsrc/Wi/ && make clean && cd ../..

Do you know how to fix this?

We are trying to get Virtuoso working on all our release platform so that
the soon upcoming Debian "Squeeze" 6.0 release can has a KDE with Semantic
Web functionalities on all platforms, powered by Virtuoso.

Cheers

Arthur
