The directory structure for the OS/2 port is laid down in
named/pathnames.h. See section Directory layout for further information
and means to fit your personal setup without recompiling. The EMX
runtime and IBM TCP/IP have to be installed. HPFS is required.
You will find the executables in the source directories
(named/, tools/,
tools/nslookup), make install does (of
course) not work (yet).
It is a good idea to have syslogd running the first time
you start named. Try parameter -d for
extensive debug info and/or -q for query logging. Default
log level is 1; a log level of -d 20 produces over 60 kb
of output during the first 2 seconds - beware...
OS/2 specific stuff
What happened to the code?
Actual code is pretty unchanged, I adapted the makefiles (and named 'em
Makefile.OS2, so make sure to type make -f Makefile.OS2
from the bind distribution root directory, issuing make
from subdirectories won't work), figured out a suitable
compat/lib/lib44bsd.a, read
conf/protability.h very carefully :) and while doing so my
OS/2 box turned into a unix-lookalike (you may wish to get GNU
shell|file|text utilities, sed 3.0, flex 2.4.5, ksh 5.27, ... from
hobbes).
Look for __EMX__ defines in the code (you won't find many) to see what changed.
Upon request (I was really forced to do so:) I made the path-setup somewhat more dynamic for OS/2 -- now the code evaluates the environment variables ETC, TMP and TEMP and adapts accordingly. Two (hopefully) new environment were introduced:
/tcpip/bin/named-xfer is used)
named looks for TMP/namedb/named.boot)
nslookup assumes to find its helpfile as
/tcpip/help/nslookup.help)
nice() and renice() code has been
replaced with dummy code, so the OS/2 port may consume more CPU time
than neccessary.
named this time.
In order to re-compile the bind port you'll need a syslog
library (on hobbes or cdrom.com; for IBM's CSet, a
port of the port to EMX is available from the author) and flex 2.4.5.
/emx/include/sys/time.h was extended to include stuff we
need for setitimer(). Maybe we will see this in one of the
next EMX distributions\dots [bad hack :)]
I removed the contrib/, shres/,
doc/rfc/ directory from the original distribution, some
postscript files about DNS security were also removed. If you are
interested, just ftp the
latest bind distribution.
A way to send signals under OS/2 is provided with the Apache httpd port. See the
OS2/ directory in the OS/2 Apache archive.
bind493a.zip, initial
release
bind493b.zip contains a wonderful
LaTeX-README and, more important, a fix for the 'core dump' bug when
set up as a secondary name server (well, now everything is linked
static); some cleanups were done to the Makefiles; this is just an
update release, it contains only executables and this
README!
bind493c.zip to fix a bug
which occurred when transferring a zone; it contains only named.exe and
an updated README.

full at exit and we take away the final buffer. this is really a
kernel bug but it's harmless on systems that are not broken, so...*/
compat/lib/rename_unixstyle.c).
nsloopup.help is now searched in
the path specified by the HELP environment variable; the following
optional environment variables are supported now: NAMED_XFER may point
to the named-xfer program, NAMED_BOOT locates the
named.boot file and NSLOOKUP_HELP may point to the
nslookup.help file; important: upon request
temporary files are now created in /tmp (not in
/temp anymore) per default, set TMP or TEMP environment
variable to override this behaviour.

named, these shell scripts in the named\-directory won't work for us.
I'm very interested in your comments and flames about the OS/2 port of bind:
Still, if everything is running fine please tell me the domain you are
serving with this bind port, just for my ego :)
