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.
|
|
|
|
SunOS 5 (aka Solaris 2) problems
|
|
--------------------------------
|
|
|
|
When building shared libraries and using some combinations of GNU gcc/ld
|
|
you better set the environment variable RUN_PATH to /usr/athena/lib
|
|
(your target libdir). If you don't, then you will have to set
|
|
LD_LIBRARY_PATH during runtime and the PAM module will not work.
|
|
|
|
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'.
|
|
|
|
IRIX problems
|
|
-------------
|
|
|
|
IRIX has three different ABI:s (Application Binary Interface), there's
|
|
an old 32 bit interface (known as O32, or just 32), a new 32 bit
|
|
interface (N32), and a 64 bit interface (64). O32 and N32 are both 32
|
|
bits, but they have different calling conventions, and alignment
|
|
constraints, and similar. The N32 format is the default format from IRIX
|
|
6.4.
|
|
|
|
You select ABI at compile time, and you can do this with the
|
|
`--with-mips-abi' configure option. The valid arguments are `o32',
|
|
`n32', and `64', N32 is the default. Libraries for the three different
|
|
ABI:s are normally installed installed in different directories (`lib',
|
|
`lib32', and `lib64'). If you want more than one set of libraries you
|
|
have to reconfigure and recompile for each ABI, but you should probably
|
|
install only N32 binaries.
|
|
|
|
GCC had had some known problems with the different ABI:s. Old GCC could
|
|
only handle O32, newer GCC can handle N32, and 64, but not O32, but in
|
|
some versions of GCC the structure alignment was broken in N32.
|
|
|
|
This confusion with different ABI:s can cause some trouble. For
|
|
instance, the `afskauthlib.so' library has to use the same ABI as
|
|
`xdm', and `login'. The easiest way to check what ABI to use is to run
|
|
`file' on `/usr/bin/X11/xdm'.
|
|
|
|
Another problem that you might encounter if you run AFS is that Transarc
|
|
apparently doesn't support the 64-bit ABI, and because of this you can't
|
|
get tokens with a 64 bit application. If you really need to do this,
|
|
there is a kernel module that provides this functionality at
|
|
<ftp://ftp.pdc.kth.se/home/joda/irix-afs64.tar.gz>.
|
|
|
|
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
|
|
8321
|
|
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::.
