Dear sirs,
I tried to compile openssh-5.0p1 on a IRIX machine with gcc.
"/sbin/uname -a" gives:
IRIX o2 6.5 07202013 IP32 mips
and "/sbin/uname -R" gives:
6.5 6.5.30f
"gcc -v" gives:
Reading specs from /usr/freeware/lib/gcc-lib/mips-sgi-irix6.5/3.3/specs
Configured with: ../configure --prefix=/usr/freeware
--enable-version-specific-runtime-libs --disable-shared --enable-threads
--enable-haifa --enable-libgcj --disable-c-mbchar
Thread model: single
gcc version 3.3
Talking about OpenSSL libraries and headers, "./configure" says that:
checking OpenSSL header version... 90807f (OpenSSL 0.9.8g 19 Oct 2007)
checking OpenSSL library version... 90807f (OpenSSL 0.9.8g 19 Oct 2007)
"./configure" complains about <sys/stropts.h>:
[...]

checking sys/stropts.h presence... yes
configure: WARNING: sys/stropts.h: present but cannot be compiled
configure: WARNING: sys/stropts.h: check for missing prerequisite headers?
configure: WARNING: sys/stropts.h: see the Autoconf documentation

configure: WARNING: ## ------------------------------------------- ##

Nevertheless a "Makefile" and "config.status" is still
produced.
Issuing a "make" the compilation stops at
[...]
gcc -g -O2 -Wall -Wpointer-arith -Wuninitialized -Wsign-compare
-std=gnu99 -I. -I.. -I. -I./.. -I/usr/local/ssl/include
-DHAVE_CONFIG_H -c bsd-openpty.c
saying that:
In file included from bsd-openpty.c:61:
/usr/include/sys/stropts.h:237: error: parse error before
"t_uscalar_t"
/usr/include/sys/stropts.h:261: error: parse error before
"t_uscalar_t"
/usr/include/sys/stropts.h:267: error: parse error before '}' token
make[1]: *** [bsd-openpty.o] Error 1
make[1]: Leaving directory `/mnt/d0/software/openssh-5.0p1/openbsd-compat'
make: *** [openbsd-compat/libopenbsd-compat.a] Error 2
But an IRIX-based system has <stropts.h>, which in turns includes
<sys/stropts.h>.
So I made a "make distclean" and in:
- configure
- configure.ac
- openbsd-compat/bsd-openpty.c
- config.h.in
I changed all the occurrences of the string "sys/stropts.h" to a
straight "stropts.h"
Something like this, I mean:
*** bsd-openpty.c Mon Apr 14 09:06:12 2008
--- bsd-openpty.c.orig Mon Apr 14 09:06:50 2008
***************
*** 58,64 ****
# include <pty.h>
#endif
#if defined(HAVE_DEV_PTMX) && defined(HAVE_SYS_STROPTS_H)
! # include <stropts.h>
#endif
#include <signal.h>
--- 58,64 ----
# include <pty.h>
#endif
#if defined(HAVE_DEV_PTMX) && defined(HAVE_SYS_STROPTS_H)
! # include <sys/stropts.h>
#endif
#include <signal.h>
"configure" still complains about "present but not compiled"
but I got through "make" with a successful
compilation and working executables which I'm happily using
right now.
Conclusions:
Maybe could any of that be useful for you developers?
I have just a question: am I putting something nasty in my
sshd daemon?
Please, feel free to get in touch with me for any question
regarding this topic. I realize IRIX is not a very common
OS (alas, I'd say) but there are few of us out of there still
using IRIX with such a delight :)
Best regards.
