Hi
I'm really desperate; does any of you have experience with writing a custom collation driver for Interbase?
I've downloaded a paper describing how to do that with examples included but I don't get it all up and running; the URL is
http://www.ibphoenix.com/main.nfs?a=ibphoenix&page=ibp_collation
I had to adapt the makefile a little until I was able to compile
gdsintl2.dll. Now I wanted to run the cs_example.sql file (to be found
at the above link) but when I start it, I get a lot of error messages
so would any of you please have a look at my console log and tell me
what the problem ist:
