What does that error mean? How to fix it?

Hi,

When I start icfb command, i get the follwing error message in the
calling terminal, then it starts normally, however i am not sure if
there's internal problems.

This is the error message:
"Incorrectly built binary which accesses errno or h_errno directly.
Needs to be fixed."

Thanks and regards,
Ahmad

 

Hi Ahmad,

I've had a similar problem couple of years ago when moved a machine
from RH 7.2 to RH Entreprise Linux 3.0.
I think this was because the Redhat Version (kernel version) I was
using was not supported by Cadence and the solution to make working at
this time is to set an env variable called LD_ASSUME_KERNEL to 2.4.1

So my first advice is to follow the same, it may help.
So before running Cadence, set up your Unix environment by adding :
CSH> setenv LD_ASSUME_KERNEL 2.4.1
or
SH> LD_ASSUME_KERNEL="2.4.1" ; export LD_ASSUME_KERNEL

You can get your kernel version by using the following unix command :
UNIX> uname -r
==> 2.6.22.5-31-default (In my linux box). I would have tried
LD_ASSUME_KERNEL="2.6.2" in my case. Well give it a try and see how it
goes.

I'm very happy for you if this fixes your problem otherwise you need
more inverstigation and it's worth involve your Cadence support for
it.

Anyway, I don't really like this LD_ASSUME_KERNEL and I'm seeing it
set by default almost everywhere.
You have to know that this variable has been introduced a while back
when Linux was changing threading models. Those new models have broken
many applications like Java.This env variable have been introduced
then to get back the the old threading behavior. This was ages ago
when transition was needed but thinks are ine now.Setting
LD_ASSUME_KERNEL could be harmful for certain applications today. Just
Google it if you want to read more about this.

What is your opinion Guys ?

These days you don't really need to set LD_ASSUME_KERNEL most of the time. The
particular error message could either be ignored, or in fact in more recent
versions doesn't happen any more.

LD_ASSUME_KERNEL on RHEL5 (which I'm using, for various reasons, discussed in an
earlier post - even though it's not fully "supported" for all releases) breaks
pretty much everything (even "ls"), so I tend not to use it.
