hello ,

=20=20
   1.  I compiled and linked two source files one=20=20=20=20=20=20=20
       of which is c and other is c++ . I called=20=20=20=20=20=20=20=20
       a function which was in c++ file from c file .=20=20=20
       gcc flagged an error..

       I gave :
=20
       $>gcc a.c a.cpp

        Error was  : undefined reference to that=20=09
               	     function
=20=20=20
        When i ran the same with g++ , it worked
=20
        $>g++ a.c a.cpp=20
=20
         No error

         What happens exactly ?

      2. Now i want to add c++ code to objc compiler=20=20=20=20
         cc1obj . i.e i will link one more file which=20=09
	 is .cpp with other objc source files which are=20
          .c . Here the same problem arises .
          The thing that we can't make here compiler=20=20=20=20
         g++ as it happens through stages..and it=20=20=20=20=20=20=20
         changes

           What can be done for this ?

=20=20=20=20=20=20=20=20
         Thanking you in anticipation ...
