dtrnlspbc_init problem

Hi, All,
when i use the trust region algorithm, i meet some problem with "dtrnlspbc_init"
What i got is the return of "TR_INVALID_OPTION"
I have checked my parameters, it seems there is no obvious error.
I don't know what else situation, such kind of return may happen?
thank you very much!

Can you show the appriopriate lines of code (with parameter(s)) values? It's hard to give any advice without it.

Thank you very much for your kind reply.
I have tried the standard example, it doesn't succeed either.
So i modify the link library and it works now.
I am a green hand in intel library.
i don't know what is the
difference between ilp64 and lp64?
my CPU is Core 2 Duo, and my system is Win XP 64.

well, I didn't help you at all. ilp64 and lp64 are integer models specific for x64 platform. Take a look at Chapter 3 Support for ILP64 Programming in User's Manual.
