Hi all,

     I encounter problems building root 5.26 or 5.30 from source on a CentOS system, both using the system or the root provided libz:

uname -a
Linux a.b.org 2.6.18-lustre21 #1 SMP Thu Jun 9 00:39:39 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

gcc --version
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-50) Copyright (C) 2006 Free Software Foundation, Inc.

yum list zlib
...
Installed Packages

zlib.i386                          1.2.3-4.el5                         
installed
zlib.x86_64                        1.2.3-4.el5                         

installed

1. If I use

./configure linuxx8664gcc
make
.....

     Any ideas what went wrong?
