kline@ux1.cso.uiuc.edu (Charley Kline) (12/22/90)
I just finished a port of X11R4. With a little help from Bill Moran (whose
xterm patches are necessary but not sufficient), everything now works except
xterm, which works mostly but leaves a couple of termio settings undone (and
I have no way to set them without major hacking on the xterm code, a twisty
little maze of #ifdefs, all mostly alike).
Some words of wisdom garnered from my build notes, admittedly a bit terse:
* Set the environment variable IMAKECPP to /usr/lpp/X11/Xamples/util/cpp/cpp
before building, (or hack imakemdep.h to change the default definition of
DEFAULT_CPP.
* You'll need BOOTSTRAPCFLAGS (I set it to -Drs6000).
* Change Imake.tmpl to key on the rs6000 symbol, and make an RS6000.cf
config file. Mine looks like this:
#define OSMajorVersion 3 /* S/6000 AIX Version 3.1 */
#define OSMinorVersion 1
#define SystemV YES
#define OSName AIX 3.1
#define HasNdbm YES
#define CppCmd /usr/lpp/X11/Xamples/util/cpp/cpp
#define PreProcessCmd /usr/lpp/X11/Xamples/util/cpp/cpp
#define StandardCppDefines -Drs6000 -DSYSV
#define BuildServer NO
#define BootstrapCFlags -Drs6000
#define OPERATING_SYSTEM AIX
#define LibraryDefines -DUNIXCPP ibmlibdefs StandardDefines
#define StandardDefines -Drs6000 -DSYSV -DMALLOC_0_RETURNS_NULL
#define LintOpts -ax -Drs6000
#define SpecialMalloc YES
#define ibmSpecialMalloc YES
* Follow the directions in imakemdep.h carefully!
* I found things to work better when I left the xlc.cfg file alone; i.e.,
DON'T try to make the C compiler behave more like the bsd one.
* A few source changes were necessary. Most are trivial, two are massive.
I used #ifdef rs6000 around all my changes to keep things portable. You
should too.
X11/Xos.h
after comment "Get struct timeval", arrange for the following
set of conditionals to include both <time.h> and <sys/time.h>.
There are a couple of ways to do this.
lib/Xaw/Text.c
cast required near line 1560 to keep compiler happy because
operands on either side of the : in a ?: operator were of
wrong types (hereafter referred to as ?: type check).
clients/bitmap/bitmap.c
#include <math.h> needs to be moved up to the top with the
other includes, and the declaration of malloc near line 165
needs to be ifdeffed out.
clients/xmh/command.c
#include <sys/select.h> needs to be added.
clients/xpr/pmp.h
#undef FALSE and #undef TRUE before the declaration of
enum bool.
clients/xpr/x2pmp.c
declaration of calloc near line 37 needs to be ifdeffed out.
clients/xdm/dm.h
declaration of strcpy near line 218 needs to be ifdeffed out
(in AIX this is an in-line optimization by the compiler, so
degenerates to a macro).
clients/xman/man.c
change all calls to realloc to calls to Xrealloc (this is a
more general oversight than for the S/6000!). Change #ifdef USG
to #if defined(USG) || defined(rs6000) at line 443.
clients/twm/events.c
?: type check near line 1418.
clients/twm/iconmgr.c
declaration of strcmp near line 43 needs to be ifdeffed out
for the same reason as strcpy did.
clients/xterm
massive changes required in main.c, mostly having to do with
the unique pty naming scheme under AIX and the fact that the
#ifdefs seemt to take everything into account EXCEPT the POSIX
terminal I/O that AIX likes to use. I hope someone will
correct me if I'm wrong. I still don't have this right. We're
still using the "aixterm" program supplied with X11R3.
clients/xload/get_load.c
AIX doesn't keep the load average in the kernel! I had to add
some code to do this; the result looks just like a real load
average display except all the math is being done by
get_load.c, not the kernel. Contact me for details. For this
reason...
clients/xload/Imakefile
EXTRA_LIBRARIES = -lm since I call exp() in get_load.c.
util/scripts/bsdinst.sh
needs to be modified because /etc/install under AIX expects
-M to set the mode instead of -m.
