- These are hints for people building X11R5 with AIX3.2. BTW, the X11R5
- parts of the FAQ is way old: the section by Andy Pierce probably should
- be deleted because it is no longer relevant.

- Sections of this posting
- 1. Fun with xlc 1.2.0.x (AIX3.2)
- 2. BSD 4.4 networking (AIX3.2)
- 3. xdm and /etc/environments
- 4. Contrib patches

- --------------------
- Fun with xlc 1.2.0.x
- --------------------
-
- I've had problems with every version of XLC in AIX3.2 that I've installed.
- To find out what version you have, type "lslpp -h xlccmp.obj".
-
- xlc 1.2.0.0:
- Eats >50megs of page space on large files when optimizing; ANSI
- mode flags legitimate constructs as errors. Because of the large
- time and space requirement, it fails to finish in finite time.
- Solution: Don't build optimized, so in the file mit/config/ibm.cf,
- add somewhere after "#ifdef RsArchitecture":
- #define OptimizedCDebugFlags
-
- xlc 1.2.0.5
- Still problem with optimizing: use above solution.
-
- xlc 1.2.0.7
- Faulty inlining of memcpy(). To turn off,
- #define OptimizedCDebugFlags -O -D__STR31__
-
- xlc 1.2.0.12
- Have not installed yet but inlining of memcpy() fixed.
-
-
- --------------------
- BSD 4.4 networking
- --------------------
-
- In AIX3.2, because of changes in the socket address structure for
- BSD4.4 networking, mit/lib/X/XConnDis.c must be patched for UNIX
- domain sockets to work. Note that these are not full patches, so do
- _not_ turn off the network option "compat_43" (to check, type "no -a"
- and look for "compat_43 = 1") or else TCP/IP sockets will break. The
- full patch, unfortunately, hits a _lot_ of files. Save patch to
- sky-aix32.patch and type:
-
- mv sky-aix32.patch mit/lib/X
- cd mit/lib/X
- cp XConnDis.c XConnDis.c.save
- patch -p -s < sky-aix32.patch
- make libX11.a

-
- addr = (struct sockaddr *) &unaddr;

- -------
-
-
- --------------------
- /etc/environments
- --------------------
-
- If you use xdm, you should add this to "/usr/local/lib/X11/xdm/xdm-config"
- so that you get the system environment variables set:
-
- DisplayManager.exportList: TZ LANG LOCPATH NLSPATH ODMDIR
-
-
- --------------------
- Contrib patches
- --------------------
-
- Patches to improve the performance of the colorgda adapter (aka, skyway)
- are available by anonymous ftp from export.lcs.mit.edu. Look for
-
- contrib/sky.README
- contrib/sky-perf-1.tar.Z
- contrib/sky-cfb.patch
-
- The above BSD4.4 networking patch is also in
-
- contrib/sky-aix32.patch
