OCCI (Oracle 9i) in cygwin on W2K

Question

I would like to know if it's possible to compile and link the samples (for example occipool.cpp) in cygwin.
I am having problems to link to the Oracle libraries. They all seems to be .lib and I was expecting something like .a or .so
Thanks.

Answer 1

Maybe I was not clear, but what I want to link with, are the OCCI libraries. And for some reason, this is not working (that's why I ask here and not in Cygwin forums).
The compilation was fine, but the linking gives the message :
undefined reference to `oracle::occi::Environment::createEnvironment
That's Oracle specific.
You say that there's a version using gcc 2.95.x does it have something to do with this :

But this solution works for RedHat and I am using Cygwin.
Please tell me if it is possible to link from Cygwin with libraries of the Oracle9i W2K installation.
Here is the command :
