[R] Are sockets supported on Irix?

Tue Mar 20 17:15:59 CET 2001

You didn't mention it (and I haven't learned how to read the configure
script yet), but if the include of tcp.h failed, would that cause
HAVE_BSD_NETWORKING to be undefined?  Here is the relevant portion of
config.log:

configure:9643: checking for netdb.h
configure:9653: gcc -E -I/usr/people/setzer/programs/include
-I/usr/local/includ
e  conftest.c >/dev/null 2>conftest.out
configure:9643: checking for netinet/in.h
configure:9653: gcc -E -I/usr/people/setzer/programs/include
-I/usr/local/includ
e  conftest.c >/dev/null 2>conftest.out
configure:9643: checking for netinet/tcp.h
configure:9653: gcc -E -I/usr/people/setzer/programs/include
-I/usr/local/includ
e  conftest.c >/dev/null 2>conftest.out
In file included from /usr/include/netinet/tcp.h:29,
                 from configure:9649:
/usr/include/sys/endian.h:32: #error "<standards.h> must be included before
<sys
/endian.h>."
configure: failed program was:
#line 9648 "configure"
#include "confdefs.h"
#include <netinet/tcp.h>

Indeed, netinet/tcp.h includes sys/endian.h, which has the following
notation:

/*
 * NOTE: Use of this file is deprecated. Though, if this file should be
 *       included in a program, standards.h should be included before
 *       endian.h
 */
#if !defined(_SGIAPI)
#error "<standards.h> must be included before <sys/endian.h>."
#endif

standards.h defines _SGIAPI (so why not just replace the #error statement
with #include <standards.h>?  just rhetorical)

I don't know about that system. The message means that configure set
HAVE_BSD_NETWORKING to be not defined, and to define it headers
netdb.h, netinet/in.h and sys/socket.h are needed and connect
and gethostbyname need to be found.  You need to look in config.log to see
what happened.

It's possible that you need to specify some other libraries via LIBS.
We are not aware of many people using Irix, nor of many people using that
socket mechanism, so the intersection might be empty.
