How am I to install the 32-bit version of Google's NaCl SDK?

Question

I'm looking at playing with Google's Native Client SDK, so I've downloaded the tool to install it, installed pepper_46, and attempted to build the "getting started" project, and I was given the following response.

As far as I can tell, the relevant parts are [Errno 8] Exec format error and Command was: /home/rob/.../bin/clang. After a touch of investigation, I found this.

rob@asmodeus:~/Downloads/nacl_sdk/pepper_46/toolchain/linux_pnacl/bin$ file clang
clang: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.24, BuildID[sha1]=a828789c24cefbb485103da1bf609d35e447dda2, stripped
rob@asmodeus:~/Downloads/nacl_sdk/pepper_46/toolchain/linux_pnacl/bin$

The worrying part of this is "x86-64", as my system is a plain x86 system! Google's page covering installing the SDK states that it supports x86-32, but does not say how to do it, and I have not been able to find 32-bit binaries anywhere or a way to install them. How do I go about getting a 32-bit set of these files?

Answer 1

After doing some more research, I have found that even though Google does state support for x86-32 for NaCl, they do not support it for the SDK.
