64-bit C Compiler

[Ankit Grover]

I am working on HP Itanium Machine(HP-UX B.11.23 IA64). While trying to compile C programs using cc compiler, it is making 32-bit C objects. What settings need to be made to compile them into 64-bit objects?

I am using ANSI C compiler and cc is pointing to /opt/ansic/bin.
(fnsonld)hpux1572:/opt/ansic/bin>ll

It is not a setting, but a compiler flag

# man cc would have told you

# cc +DD64 -o foo foo.c

Enjoy, Have FUN! H.Merijn
