CAUSE

This is because the gcc used by the installer to relink the binaries is 32bit which should not be the case while installing 64bit software.

SOLUTION

Query the following :

1. : gcc -v

The output displayed is:

Using built-in specs.
Target: i386-redhat-linux

The actual output should be:

gcc -v
Using built-in specs.
Target: x86_64-redhat-linux

64 bit gcc should be picked up by the installer .

Before doing the install check that 64 bit gcc is installed and in use.

2.  : rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep gcc

Output should show:

gcc-4.4.6-4.el6 (x86_64)
gcc-c++-4.4.6-4.el6 (x86_64)

3. : ls -ltr /usr/lib/gcc/x86_64-redhat-linux

4. Else, point the gcc to use 64 bit version by creating a link:

: ln -s /usr/bin/x86_64-redhat-linux-gcc /usr/bin/gcc

: ln -s /usr/bin/x86_64-redhat-linux-g++ /usr/bin/g++
