Problems compiling Kerberos
|
|
===========================
|
|
|
|
Many compilers require a switch to become ANSI compliant. Since krb4 is
|
|
written in ANSI C it is necessary to specify the name of the compiler
|
|
to be used and the required switch to make it ANSI compliant. This is
|
|
most easily done when running configure using the `env' command. For
|
|
instance to build under HP-UX using the native compiler do:
|
|
|
|
datan$ env CC="cc -Ae" ./configure
|
|
|
|
In general `gcc' works. The following combinations have also been
|
|
verified to successfully compile the distribution:
|
|
|
|
`HP-UX'
|
|
`cc -Ae'
|
|
|
|
`Digital UNIX'
|
|
`cc -std1'
|
|
|
|
`AIX'
|
|
`xlc'
|
|
|
|
`Solaris 2.x'
|
|
`cc' (unbundled one)
|
|
|
|
`IRIX'
|
|
`cc'
|
|

|
Linux problems
|
|
--------------
|
|
|
|
The libc functions gethostby*() under RedHat4.2 can sometimes cause
|
|
core dumps. If you experience these problems make sure that the file
|
|
`/etc/nsswitch.conf' contains a hosts entry no more complex than the
|
|
line
|
|
|
|
hosts: files dns
|
|
|
|
Some systems have lost `/usr/include/ndbm.h' which is necessary to
|
|
build krb4 correctly. There is a `ndbm.h.Linux' right next to the
|
|
source distribution.
|
|
|
|
There has been reports of non-working `libdb' on some Linux
|
|
distributions. If that happens, use the `--without-berkeley-db' when
|
|
configuring.
|
|
|
|
HP-UX problems
|
|
--------------
|
|
|
|
The shared library `/usr/lib/libndbm.sl' doesn't exist on all systems.
|
|
To make problems even worse, there is never an archive version for
|
|
static linking either. Therefore, when building "truly portable"
|
|
binaries first install GNU gdbm or Berkeley DB, and make sure that you
|
|
are linking against that library.
|
|
|
|
Cray problems
|
|
-------------
|
|
|
|
`rlogind' won't work on Crays until `forkpty()' has been ported, in the
|
|
mean time use `telnetd'.
|
|
|
|
AIX problems
|
|
------------
|
|
|
|
`gcc' version 2.7.2.* has a bug which makes it miscompile
|
|
`appl/telnet/telnetd/sys_term.c' (and possibily `appl/bsd/forkpty.c'),
|
|
if used with too much optimization.
|
|
|
|
Some versions of the `xlc' preprocessor doesn't recognise the
|
|
(undocumented) `-qnolm' option. If this option is passed to the
|
|
preprocessor (like via the configuration file `/etc/ibmcxx.cfg',
|
|
configure will fail.
|
|
|
|
The solution is to remove this option from the configuration file,
|
|
either globally, or for just the preprocessor:
|
|
|
|
$ cp /etc/ibmcxx.cfg /tmp
|
|
$ed /tmp/ibmcxx.cfg
|
|
8328
|
|
/nolm
|
|
options = -D_AIX,-D_AIX32,-D_AIX41,-D_AIX43,-D_IBMR2,-D_POWER,-bpT:0x10000000,-bpD:0x20000000,-qnolm
|
|
s/,-qnolm//p
|
|
options = -D_AIX,-D_AIX32,-D_AIX41,-D_AIX43,-D_IBMR2,-D_POWER,-bpT:0x10000000,-bpD:0x20000000
|
|
w
|
|

|
|
q
|
|
$ env CC=xlc CPP="xlc -E -F/tmp/ibmcxx.cfg" configure
|
|
|
|
There is a bug in AFS 3.4 version 5.38 for AIX 4.3 that causes the
|
|
kernel to panic in some cases. There is a hack for this in `login', but
|
|
other programs could be affected also. This seems to be fixed in
|
|
version 5.55.
|
|
|
|
C2 problems
|
|
-----------
|
|
|
|
The programs that checks passwords works with `passwd', OTP, and
|
|
Kerberos paswords. This is problem if you use C2 security (or use some
|
|
other password database), that normally keeps passwords in some obscure
|
|
place. If you want to use Kerberos with C2 security you will have to
|
|
think about what kind of changes are necessary. See also the discussion
|
|
about Digital's SIA and C2 security, see *Note Digital SIA::.
