Just to add to what Stephen wrote,
When you upload the collection to your mac, the only part of the
collection that is affected by the endian problem is the gdbm database.
The mg indexes in the collection and the associated files will be fine.
A quick way of dealing with the gdbm database is to use two utilities
provided with greenstone, db2txt and txt2db
db2txt - converts the gdbm database for a collection from binary form to
txt2db - converts the gdbm database for a collection from text form back
to binary form
You can find the gdbm database for a collection in that collections
It will be named as a *.ldb file, or a *.bdb file, the l stands for
little endian, the b stands for big endian. So on a windows machine, if
you had a built collection with the name "apples", you would find a
apples.ldb file here: gsdl\collect\apples\index\text\apples.ldb
So, to successfully transfer your gdbm database from a windows machine
to a mac, you would need to use the db2txt utility on the windows
machine, to convert the *.ldb file to a text form, something like this
db2txt apples.ldb > apples.ldb.txt
Once you have uploaded that ldb file to the mac, you can use the mac's
version of txt2db to convert your text version back to a *.bdb file in
this case, something like
txt2db apples.ldb.txt > apples.bdb
Put this file in the index/text directory, and your collection should
work properly on the mac.
Hope this helps,
