-----BEGIN PGP SIGNED MESSAGE-----
Last time I sent a C-related question to -chat and I was told to send it to
- -questions, so I hope this is the right list.
I have a static array of structs declated in module dblist.o as so:
static fieldInfo DB_TYPES[DB_NUMTYPES]={ blah , blah , blah };
I have an extern statement in dblist.h as follows:
extern fieldInfo DB_TYPES[DB_NUMTYPES];
I can use data fields from DB_TYPES[] fine in the dbtypes.o module. In another
module (dblist.o) I look up some fields from DB_TYPES[]. dblist.o includes
dbtypes.h and it compiles fine without any errors. However, when I try to link
both of these modules together with other assorted modules gcc tells me:
dblist.o: Undefined symbol `_DB_TYPES' referenced from text segment
Do I need to use static in the extern declaration or something? Any help
appreciated.
