Hello.
While preparing our systems to run KYLIX I have to patch glibc
libs with special version patched by Borland. While doing this
I realised a strange phenomenon on two SMP machines:
I started up with a Linux shell by typing /compat/linux/bin/tcsh
and then I tried to run rpm -i as I did this three times before on
other machines successfully. I received this:
error: failed dependencies:
/sbin/ldconfig is needed by glibc-2.1.3-22B
This looked like as Linux can not find its tools the right way
or a mixture between Linux and FreeBSD has been tasken place. I checked
with 'uname -a' what kind of environment I use and got FreeBSD
(on the three successors I got Linux!).
Netxt step was to figure out obvious differences between the machines,
but they all use the same Linux configuration as it has been installed
by the installer (linux_base). The systems of success are two UP systems with
AMD CPUs and on SMP machine with two PII - so I think it is not a point of
the difference in UP and SMP, maybe.
Then I unmounted linprocfs on one of the unsuccessful machines and tried again.
All right, after running Linux tcsh and typing uname -a I got Linux as expected.
Then I cd'ed to my source directory, tried rpm again - and got the same error!
Immediately after receiving this error again I typed uname -a again and got
FreeBSD!
It seems that Linux emulation is switching ... This happens exactly the same way
on another SMP server. The strange behaviour showing uname -a (I use this to check
in which 'mode' I'am actually) is shwoing up not in a deterministic way and it is
really strange and surely a bug!
I reported a few days ago strange things regarding to Lahey F95 compilated software.
A simple Fortran prgram 'hello world' runs after compilation on these machines the first
time - if it get called a second time it shows an libc error regarding to getcwd.
Has anyone a suggestion?
