Hi Jeremy,

The trouble you're having might be due to the gdbm database for your
collection being incompatible with Windows.

After you build your collection on Mac OSX there should be a file called
something like gsdl/collect/your-collection/index/text/your-collection.bdb
(where "your-collection" is the name you've given your collection). This
file is the GDBM database containing all the metadata and such for your
collection. Unfortunately GDBM is endian specific so building your
collection on a big-endian computer (e.g. Mac OS X) creates a GDBM database
that won't work on a little endian machine (e.g. Windows).

What you need to do is to create a little-endian version of the GDBM
database, call it your-collection.ldb (as opposed to your-collection.bdb for
the big-endian file) and put it in the your-collection/index/text folder of
your exported collection.

The easiest way to create a little-endian version of your GDBM is to first
convert the big-endian file to text on a big endian machine, then copy the
text file to a little-endian machine and convert it to a little-endian GDBM.
To do that follow these steps:

1. On your Mac OS X machine open a shell and change directory to your gsdl
directory.

2. There should be a program in $GSDLHOME/bin/darwin called db2txt. Run that
program in the following way to convert your GDBM database to a plain text
file.
db2txt your-collection.bdb > your-collection.bdb.txt
This should create a "your-collection.bdb.txt" file that's a plain text
version of the "your-collection.bdb" GDBM database.

3. Copy the text file to a windows box.

4. On the windows box, in $GSDLHOME/bin/windows, there should be a program
called txt2db.exe. Use this program to convert your text file to a
little-endian GDBM database. Use a command like the following
txt2db your-collection.ldb < your-collection.bdb.txt

5. Copy the your-collection.ldb file you created back to your Mac OS X
machine and put it in the gsdl/collect/your-collection/index/text folder
(i.e. the same folder as the your-collection.bdb file lives).

6. Re-export the collection - this time the .ldb file will be exported along
with it.

If you have trouble converting your GDBM database send it to me off list and
I'll do it for you.

Stefan.
