[Insight-users] Linking problem [optimizer?]

[J Mst]

Hi all,

I was making a little programming which can do registration. I use an MFC 
interface. The compiling process is going ok but when VC++ start linking I 
get the following error message:

I have tried many different ways to "call" the optimizer.. but without 
success. Does anyone know how to correct my problem??

Many thanx in advance
