I'm working on a HP-UX IA box:
$ uname -a HP-UX t06 B.11.23 U ia64 2438279764 unlimited-user license
With gcc 3.3.2:
$ gcc --version
gcc (GCC) 3.3.2
Copyright (C) 2003 Free Software Foundation, Inc.

When I try to compile this file:
#include <net/if.h>
int main()
{
}With gcc, everything works fine. But if I use g++, not ok:
$ g++ -c test.c -o test
In file included from test.c:1:
/usr/include/net/if.h:181: error: 'uint64_t' is used as a type, but is not defined as a type.
But, if I use g++ with "-U__STDC_EXT__" (or -mlp64, but I need -milp32 to work), it works:
$ g++ -U__STDC_EXT__ -c test.c -o test
<command line>:4:1: warning: undefining "__STDC_EXT__" $
The problem seems to be with a line in net/if.h:
/* Note: The extended flags field "ifru_xflags" is a uint64_t which is not * a valid type for strict ANSI C compilation for ILP32. Applications that * need access to extended flags field should be compiled in extended ANSI * (-Ae) or LP64 mode. */
#if defined(__STDC_EXT__) || defined(__LP64__)
Is there a better way to do this than by undefining __STDC_EXT__? Or is it be safe to undefine that? I've tried searching google and these mailing lists with no luck... Or should I be sending this question to HP?
Thanks- Ryan
