c# - Issue with importing tlb into c++ client code -


suppose have following definitions : 

namespace baseifsnamespace   //defined in assembly a1 {     [comvisible(true)]     [guid("2e6cb2b7-8884-4250-87a5-83bf52ee5d29")]     public interface baseifs     {         void testm(string s1);     } }

and 

namespace derivedcom  //defined in assembly a2 {     [comvisible(true)]     [progid("derivedcom.derivedcom")]     [guid("ac01fd21-4708-4296-9b2e-b268bc1d880b")]     //[classinterface.none]     public class derivedcom : baseifs     {         public void testm(string s1)         {             //some implementation         }      } }

i generate type libraries a1.tlb , a2.tlb correspondingly. when use a2 in c++ client code following

#import "c:\path11\derivedcom.tlb" no_namespace raw_interface_only

i got error c1084 typelibrary cannot imported. how correctly should generate tlbs ( checked regasm ) , there need somehow define a2.tlb depends on tlb1 ? saw related post here , know openning oleview can locally resolve issue need more common solution ( work on build server ) in advance
