bdbstore status

[Jim Meyering <ji...@meyering.net>]

FYI, I've converted bdbstore to use autoconf, automake, and libtool.
And now it compiles with the same set of warning options used by qpidc.
It builds and passes "make check" on Debian unstable, and builds
but fails the system_test.sh check on rawhide.

In case anyone can guess the cause off hand, I've included
valgrind output and a gdb stack trace below.  For reference,
here's the command I used:

  libtool --mode=execute valgrind ../../qpidc-0.1/src/qpidd \
    -s ../lib/.libs/libbdbstore.so

BTW, to get this far, I needed not only qpidc (aka cpp), but also the
python/ and specs/ directories in order to be able to run the tests.

Here's the valgrind output:
