Thanks for your reply. Will the hello executable execute the code of dynamic linker from the file a.out.c in the following directory /usr/src/cmd/sgs/rtld/common
But I have a i386 machine and I don't know why cc is not taking -xarch=v8. Though -xarch=generic or -xarch=386 are working. Also why the executable file shows as ELF File ? I think cc is not a cross compiler.
