A revised R4 ERRATA file has been placed on expo; here it is. Most of this
has already been discussed on xpert, although you may find a few things you
missed. Please note that any source code changes described will come out as
"official" patches in the future, so if you make them now, be prepared for
patch failures later. The file by no means describes everything we know
that's wrong with R4. :-)
R4 Errata
1. You are building servers on 680x0 or VAX platforms, you should probably
use GCC if you have it, especially for the server. However, please note
that the system has only been tested with gcc version 1.35. It is known
that the XtNewString macro in Xt miscompiles under gcc 1.36. It is also
known that some parts of the system miscompile under gcc 1.36 on the SPARC.
Make sure you have run "fixincludes" from the gcc distribution before you
build the system, or ioctl() calls will miscompile. If you have installed
your gcc-include files somewhere besides /usr/local/lib/gcc-include, you
will have to edit line 197 of the file mit/util/makedepend/main.c to
point at the proper directory.
2. If you are trying to install library files into a directory other than
/usr/lib/X11, you'll need to change XFILESEARCHPATHDEFAULT and ERRORDB
in the file mit/lib/Xt/IntrinsicI.h to point at the correct directories.
You'll also need to change SYSTEM_INIT_FILE in mit/clients/twm/parse.c.
You'll also need to add the following line to mit/lib/Xmu/Imakefile:
DEFINES = -DBITMAPDIR=\"$(INCDIR)/bitmaps\"
3. Do not turn on InstallXdmConfig as there is no longer a default directory
under mit/clients/xdm/config/. Install xdm configuration files by hand.
4. Some versions of tcsh erroneously set the eighth bit on characters they
emit. If you are not seeing text in your xterm windows and are using
tcsh, try using a different shell (e.g. xterm -e /bin/sh).
5. Sites running BSD 4.3 on vaxes will need to enable the qvss and/or qdss
servers and will need to specify -DX11R4 in the ServerDefines line in
mit/config/bsd.cf if building the qdss server:
#ifdef VaxArchitecture
#define XqvssServer Xqvss
#define XqdssServer Xqdss
#define ServerDefines StandardDefines ExtensionDefines -DXDMCP -DNOSTDHDRS -DX11R4
#endif
6. If you are building on a macII without gcc, you need to define CcCmd in
mit/config/macII.cf as follows:
#define CcCmd cc -B /usr/lib/big/
7. If you are building on a vax, the lucida typewriter fonts will not
display correctly. To correct this, change line 410 of the file
mit/fonts/bdftosnf/fontutil.c from:
inwidth = GLWIDTHBYTESPADDED (pCI->metrics.characterWidth, glyphPad);
to:
inwidth = GLWIDTHBYTESPADDED (pCI->metrics.rightSideBearing -
pCI->metrics.leftSideBearing, glyphPad);
8. If you are building with shared libraries on a Sun (we suggest that you
do), remember that you need to run "ldconfig" as root after installing
the shared libraries. While building and installing the distribution,
you need to be careful to avoid linking against any existing X shared
libraries you might have (e.g. those distributed with OpenWindows). You
should make sure you do not have LD_LIBRARY_PATH set in your environment
during the build or the installation. If you are going to keep xterm and
xload as setuid programs, please note that the shared libraries must be
installed in /usr/lib or /usr/5lib for these programs to work (or else
those programs must be linked statically).
9. The IBM server does run on the RT under AIX. It should work under AOS
on the RT, and under AIX on the PS/2.
10. Make sure your own resource files don't try to specify xterm geometry with
xterm*geometry: <...>
This will cause menu geometries to be incorrect. Instead, use one of:
xterm.geometry: <...>
xterm*VT100.geometry: <...>
The same problem may exist with other clients.
11. Various R3 clients will get protocol errors when run against an R4 server.
If you need to run these clients without fixing them, try "xset bc".
12. When the "utmpInhibit" resource is turned on, xterm exits with no error
message. To fix, change lines 1784 and 1785 of mit/clients/xterm/main.c
to:
if ((pw = getpwuid(screen->uid)) &&
!resource.utmpInhibit &&
Also change line 1855 to read:
if (geteuid() == 0 && pw)
13. If you are building the server on an old SunOS (e.g. 3.5), you will have
to add the following defines to mit/server/ddx/sun/sunCG3C.c to get it
to compile:
#define CG3AC_MONOLEN (128*1024)
#define CG3AC_ENBLEN CG3AC_MONOLEN
#define CG3BC_MONOLEN CG3AC_MONOLEN
#define CG3BC_ENBLEN CG3AC_MONOLEN
14. The twm feature to use window borders to highlight the active window is
broken. The fix is to replace lines 2458-2471 of
mit/clients/twm/menus.c with the following:
if (onoroff) {
XSetWindowBorder (dpy, tmp->frame, tmp->border);
if (tmp->title_w)
XSetWindowBorder (dpy, tmp->title_w, tmp->border);
} else {
XSetWindowBorderPixmap (dpy, tmp->frame, tmp->gray);
if (tmp->title_w)
XSetWindowBorderPixmap (dpy, tmp->title_w, tmp->gray);
}
15. The AsciiDiskSource compatibility has bugs that may cause contributed
clients to fail. Change the expression "TWO" to "ONE" on line 1309 of
mit/lib/Xaw/AsciiSrc.c, and move the call to XtMergeArgLists from
line 1302 to line 1307 (just before the call to XtCreateWidget).jne@goldhill.COM (01/13/90)

1) Is there some change to XtNewString that will make it compile correctly
under gcc 1.36?
2) Is there any other known problems with gcc 1.36 on the Sun3 and 386i.

Ok. I give up. I tried to do the right thing and reply to this message instead of following up, but the return address is worthless. | From: jne@goldhill.COM | | > It is known that the XtNewString macro in Xt miscompiles under gcc 1.36. | | 1) Is there some change to XtNewString that will make it compile correctly | under gcc 1.36? Yes. Change the form of it from: str == NULL ? NULL : ... to str != NULL ? ... : NULL Casey
