Invalid object module -- on linking C++ with MF cobol

We are trying to link a C ++ object with a MicroFocus cobol object.
On using the following command to link these objects we got the error
L1101 : Invalid object Module

Link cobol11 [+sam] + mfc6intf + c6dosif + c6doslb,,,lcobol + stdlib ;
                       here  cobol11 --- is Microfocus Cobol Obj
                               sam --- is C++ obj.

Please suggest how can we get rid of this error , Also , let us know
if there is any additional settings that needs to be done with the
compiler to get the interface working.

versions we are using : Microfocus Cobol : Ver 3.4.23
                                  Microsoft Visual C++ : Ver 6

Thanks
