OpenCL SDK on Ubuntu

--- Quote Start ---

On my CentOS 6.4 x86_64 machine I can compile with aoc but I can't run my host code without adding $ALTERAOCLSDKROOT/host/linux64/lib to the LD_LIBRARY_PATH. However, that directory has a version of libstdc++ that conflicts with the system version of libstdc++, so some other applications don't load for me while my library path includes the Altera library path.

Does anyone else experience this or any other issues with CentOS 6.4 x86_64?

Sure. For runtime you'll need the libstdc++ that is shipped with the AOCL. I'd say the best way to go around it is to call your executables from a script that exports $ALTERAOCLSDKROOT/host/linux64/lib to your LD_LIBRARY_PATH temporarily. Otherwise, it can be somewhat annoying if you try to run your OpenCL application also on a GPU and you constantly need to redefine LD_LIBRARY_PATH.

You name the following as runAOCL

# !/bin/bash

ldBak=$LD_LIBRARY_PATH

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ALTERAOCLSDKROOT/host/linux64/lib

$1

export LD_LIBRARY_PATH=ldBak

and just call runAOCL <myexecutable>

Although I'm not that sure about how to handle several arguments to your executable, something quite similar should work.
