Hi, it's me again...
I did manage to find the information on using both DLL as well as static
library but neither of them work when I try to do anything with RSA algorithm
:( I get errors when linking ;(
Here is my very short program that does nothing - it's really just a couple of
functions cut out from test.cpp:

When I try to bild it with a DLL I get this error:

I'm sorry for the lenghty post.
What am I doing wrong? What should I do? Please, I really need help :(
I've tried using the latest source from CVS but it doesn't compile :|
Best regards,
Crocodil
