[gdal-dev] Basic plugin questions

[David Adler]

If a data source is created as a plugin and GDALRegisterAll invokes 
GDALRegister_myDS, won't this cause an error at runtime if the DLL/so is 
not found?

Does GDAL need to be rebuilt specifically to include support for a 
particular plugin and then distributed separately?

Is there a repository for plugin DLL/so and how do the shared libraries 
get there?

Related to this but for the current non-plugin version of the DB2 OGR 
driver, I added
#ifdef DB2_ENABLED
     RegisterOGRDB2();
#endif
to
OGRRegisterAllInternal() in ogrregisterall.cpp
and
-DDB2_ENABLED
to
ogr\ogrsf_frmts\generic\makefile.vc

This works ok for the current ODBC-based implementation which has no 
external dependencies, but it would be better to switch to the DB2 CLI 
interface (basically the same as ODBC but supports directly platforms 
other than Windows).

Please excuse the basic questions as I'm not that familiar with how this 
all works, especially the various macro variables used in makefiles and 
source code.

Regards,
David
