README
This directory contains drivers for the DBMI library.
The driver functions are for internal usage.
The DBMI API to be used for module programming is available in:
grass6/lib/db/
NOTE:
db__driver_* functions are implemented in a driver. If some of them
are not used or defined, the driver will use stub functions in
grass6/lib/db/stubs/
For some platforms like Cygwin, multiply defined symbols are not
resolved in a way that UNIX does. Even worse is that it is impossible
to build shared libraries with undefined symbols. For example,
libgrass_dbmidriver.so cannot be built without any implementations
of db__driver_* functions which should be specific to a db driver.
To work around this problem, function pointers are defined to use
driver's implementations instead of those of the db stubs library.
To do this automatically, run '../mk_dbdriver_h.sh' in driver's
directory, #include "dbdriver.h" from main.c, and execute init_dbdriver().
Function pointers are defined in grass6/lib/db/dbmi_driver/dbstubs.h
This header file can be generated with
grass6/lib/db/dbmi_driver/mk_dbstubs_h.sh
Please read grass6/lib/db/README
