32-bit libraries needed to install C++ compiler on Linux

Hello

While installing ICC on a Debian linux system, I see this message:

Step 5 of 7 | Prerequisites > Missing Optional Prerequisite
--------------------------------------------------------------------------------
32-bit libraries not found on this system.
This product release requires the presence of 32-bit compatibility libraries
when running on Intel(R) 64 architecture systems. One or more of these libraries
could not be found:
libstdc++ (including libstdc++6)
glibc
libgcc
Without these libraries, the compiler and the debugger will not function
properly.  Please refer to Release Notes for more information.
--------------------------------------------------------------------------------
1. Finish with prerequisites and continue installation [default]
2. Back to Prerequisite summary dialog

h. Help
b. Back to the previous menu
q. Quit
--------------------------------------------------------------------------------
Please type a selection or press "Enter" to accept default choice [1]:

However I do have the latest versions of these libraries installed:
# apt-get install libgcc1:i386 libc6:i386 libstdc++6:i386
Reading package lists... Done
Building dependency tree     
Reading state information... Done
libgcc1:i386 is already the newest version.
libstdc++6:i386 is already the newest version.
libc6:i386 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 22 not upgraded.

Also added architecture i386 since my normal arch is amd64
# dpkg --print-foreign-architectures
i386

my command line:
./parallel_studio_xe_2015_update1_online.sh --cli-mode --ignore-signature

Debian version is Jessie D-I B2

I am only trying to install the C++ compiler portion, GDB and eclipse integration:
7. Intel(R) C++ Compiler XE 15.0 Update 1 [Custom]
12. GNU* GDB 7.7 [Custom]

What am I missing ? Any info would be great.
