Hi developers,
I just installed grass 5.7 on cygwin and found dbmi drivers don't work
because db_driver_* functions were defined both in
libgrass_dbstubs.dll and each driver.
For example,
db_driver_open_database in libgrass_dbstubs.dll: memory address: 0x5131f0
db_driver_open_database in dbf.exe: memory address: 0x401310
when a user calls the dbf driver, what the driver is supposed to do is
calling 0x401310. However, it calls 0x5131f0 because both the driver
and libgrass_dbmidriver.dll are compiled with libgrass_dbstubs.dll.
dbf driver (dbf.exe) -> db_driver (libgrass_dbmidriver.dll) ->
db_driver_open_database (libgrass_dbmidriver.dll ->
libgrass_dbstubs.dll, not -> dbf.exe)
I'm not sure if i explained correctly, but is this a problem only in cygwin?
Any comment would be helpful.
Thanks,
Huidae Cho
I forgot something. It causes the following error when I run ./tour in
the g51test-12 dataset:
v.db.connect map=multi.....
dbmi: db_open_database() not implemented
WARNING: Cannot open database '..../dbf'
Thanks.

I solve the problem by "make clean; make." But I don't why it happened.
