Hi,
looks like the current db2 driver code has not yet been updated to the
latest driver API. In other words, the driver fails to load because it
lacks functions considered essential by libdbi. This is not a linker
issue, therefore your ldd output is perfectly fine. There were a couple
of major changes in the past, including the introduction of instances
and of reentrant functions wherever this is needed. As none of the more
or less active developers seems to run db2, there was no chance to
update this driver. If you have some programming skills, you may use any
of the officially supported drivers, such as mysql, as a guidance to
retrofit these changes to the db2 driver.
best regards,
Markus
