When I link my application, I get an unresolved symbol error about constraint functions (e.g., extern int _cnstr_by1_fn(struct ossGlobal *, msg *, void **);). How do I get rid of this error?

To suppress such function declarations, please recompile your ASN.1 syntax with the -noUserConstraints compiler option specified. Please refer to the OSS ASN.1 Compiler Reference Manual (section 4.3.71, April 2011 edition) for more on this. Then, re-link the produced files with your application code.
