Hi Laura,

This looks exactly like a problem I frequently have.

Did you build the demo collection yourself, or get it pre-built with the
distribution? I ask because the GNU GDBM files are
architecture-dependent.

If you have a big-endian system (e.g. PPC) then Greenstone will look in
the demo collection for index/text/demo.bdb; if you have a little-endian
architecture (e.g. x86) it will look for index/text/demo.ldb. Since
you're using Solaris, and Greenstone is looking for demo.bdb, I assume
you're using SPARC hardware, which is big-endian. If you have demo.ldb
but not demo.bdb, this is your problem.

(Note that in each case, the file is a GDBM file, not a Berkeley DB file
which is also sometimes given a bdb extension).

Anyway, if you have a index/text/demo.ldb file, you can convert it to
demo.bdb in two ways. First: rebuild it with buildcol.pl. Simple.
Second: if you have an x86 installation of Greenstone handy, you can
(using the programs GSDLHOME/src/db2txt) convert demo.ldb to text with
db2txt, copy it as text to the SPARC installation, and use txt2db to
generate an equivalent demo.bdb file, and drop it in the demo/index/text
directory. I do this all the time, because I build collections on my
iBook and transfer them to my x86 Web server, and can confirm that it
works.
