[mdb-dev] compile error for 0.6pre1

[Rikul P. <rik...@gm...>]

There is a "static GHashTable *mdb_backends" declared in
src/libmdb/backend.c  but there is also a "extern GHashTable
*mdb_backends" in include/mdbtools.h .  This caused compile to fail on
 Mac OS X 10.4.7 with "gcc version 4.0.1 (Apple Computer, Inc. build
5363)" I commented out the extern declaration in mdbtools.h and it
compiled fine.
