[gnu.g++] using C header files with C++

riedl@cs.purdue.EDU (John T Riedl) (10/06/89)

I have a library of C routines that I want to use from C++.  Of
course, the function declarations in the header file are in C form
without any argument specifications (e.g., int f();).  Is there a
trick to get G++ to accept these declarations?  If not, is there a
solution that doesn't require me to make a separate header file for
G++ (with the '...' argument notation)?  How do other people solve
this problem?

Thanks,
John

Try using the -fno-strict-prototype option.  Perhaps a better
long-term solution is to get ahold of Ron Guilmette's `protoize'
program and ANSIify your header files...  You can contact 
Ron at rfg@ics.uci.edu.
