Some common questions:
----------------------------------------------------------------------
Q: My operating system isn't supported, but it was supported in Pidentd 2!
A: Please send me patches to add the needed support for Pidentd 3!
(Don't forget to make the old kernel-growling code threads safe at the
same time if you take the code from Pidentd v2!)
----------------------------------------------------------------------
Q: I use Solaris 7 and I just recompiled Pidentd. But now it
only responds with "kvm_open: Bad file number" whenever I try
to run it one our Ultra workstations.
A: Pidentd needs to be compiled with a 64 bit compiler when run
on a 64 bit platform (which almost all Ultras are). Currently
(981126) this requires atleast the WorkShop 5.0 compilers from Sun.
Gcc can not be used. Compile with:
csh/tcsh: setenv CC cc ; ./configure
sh/ksh/bash/zsh: CC=cc ./configure
----------------------------------------------------------------------
Q: I use IBM AIX 4.2 and Pidentd returns user numbers instead of names, why?
A: Because of a bug in the reentrant libc versions of getpwuid_r(). Either
install patch APAR IX60843 (recommended), or build the non-threaded
version of Pidentd (not recommended) with "./configure --without-threads".
----------------------------------------------------------------------
Q: My Unix doesn't have a threads library - where can I find one?
A: One usable Pthreads library that has been ported to a number
of Unixes is Proven's library. It can be FTP'd from:
ftp://sipb.mit.edu/pub/pthreads/
However, I do not guarantee that it will work to build a
threaded pidentd for your operating system with that threads library.
----------------------------------------------------------------------
Q: I just upgraded from Solaris 2.x to Solaris 2.y _and_ have recompiled
Pidentd - but it doesn't work (fails compilation or at runtime).
A: Make sure you are using GCC 2.8 (or later) or have updated your GCC
compiler installation so that it has installed *new* header files.
You can not use a GCC <2.8 configured for 2.x on a 2.y machine (the
"fixed" header files will be incorrect).
----------------------------------------------------------------------
Q: I just upgraded from Solaris 2.5 to Solaris 2.6 _and_ have recompiled
Pidentd, and have read question 3 - it still fails compilation:
A:
Also make sure you have applied the patch to GCC <2.8 from the Solaris FAQ:
http://www.wins.uva.nl/pub/solaris/solaris2.html
----------------------------------------------------------------------
Q: I use the beta version of IRIX 6.5 and are getting incorrect
results.
A: There is a bug in the reentrant function getpwuid_r(). You
must configure with "--without_getpw_r" and recompile (or complain
to SGI so that you'll get a fixed libc).
----------------------------------------------------------------------
Q: I just compiled it on Solaris 2.4 - and it doesn't work. All I
get is "NO-USER".
A: Make sure you have only installed _one_ of the patches:
102049-04 (I recommend this one)
102303-05
You can't have both installed at the same time.
----------------------------------------------------------------------
Q: I'm trying to compile with Gcc on Digital Unix 4.0D or 4.0E
but I'm getting errors from <c_asm.h>.
A: You must use Dig^H^H^HCompaq's own C compiler when building
multithreaded programs - or install patch kit #3 for 4.0D and
patch kit #1 for 4.0E which will fix this bug in the pthread.h
header file (it shouldn't include the c_asm.h header file for
non-DEC C compilers). Or you can manually patch the Gcc "fixed"
"pthread.h" header file so that the "#include <c_asm.h>" is moved
down one line.
----------------------------------------------------------------------
Q: I'm trying to compile with Gcc on HP-UX 9, but the server always
responds with "NO-USER" when I test it.
A: Make sure that your GCC is configured for exactly the right
machine type you are running it on. A Gcc built on a HP9K/800-series
will not build correct kernel lookup could on a HP9K/700-series
machine (and vice-versa). A workaround for HP9K/700 machines
is to build Pidentd with:
make "CC=gcc -D__hp9000s700"
