- I have found that clients/xdm/sessreg.c and clients/xterm/main.c
- won't compile in building X11R5 patchlevel 21 under RISCos 4.51
- (on a Mips Magnum 3000).
-
- The problem is associated with a missing ut_host functionality
- and so I don't think my configuration is at fault --- or is there
- something I've overlooked?
-
- Basically, RISCos is SYSV but has (most) BSD43 functionality. Thus
- we find in the Mips.cf file
-
- * X11r5 only builds using the berkeley libraries and compiler. Make
- * sure your path includes /bsd43/bin before /bin/ or /usr/bin.
-
- and
-
- #define StandardDefines -DMips -DBSD43
-
- but this crashes in the clients/xdm section:
-
- cc -O -signed -systype bsd43 -Olimit 2000 -Wf,-XNd8400,-XNp12000 -I../

- and if we push on, again in clients/xterm:
-

-
- Both of these sections of code clearly indicate that problems can be
- expected here with missing ut_host functionality in SYSV systems (while
- at the same time commenting that SYSV actually provides superior
- alternatives).
-
- Hence I managed to compile sessreg.c by hand simply by switching the
- -DBSD43 compilation flag to -DSYSV and in main.c I turned off the
- HAS_UTMP_UT_HOST switch:
-
- % diff -c main.c~ main.c
- *** main.c~ Tue Jan 5 14:53:29 1993
- --- main.c Wed Jan 6 15:04:09 1993

- #include <sgtty.h>
- #include <sys/resource.h>
- #define HAS_UTMP_UT_HOST
- + /* add Mips fix: RISCos is really SYSV */
- + #ifdef Mips
- + #undef HAS_UTMP_UT_HOST
- + #endif /* Mips */
- #define HAS_BSD_GROUPS
- #endif /* !SYSV */
-
- but I don't understand the dependencies on this code and so can't be sure
- this will work; nor can I understand how this flaw has survived without
- being fixed by now.
-
- Is there a known workaround? I would have expected this code to have
- Mips dependencies extensively built in to take advantage of the SysV
- nature of RISCos. But no. What gives? Wouldn't something like
- HAS_UTMP_UT_HOST be useful in sessreg.c?
-
- If you e-mail a reply please note my address below. This is being
- posted by roundabout means and hitting reply almost certainly
- won't work.
