I am in the process of making my code compatible with Intel Cluster Studio 2011 XE and I came across an issue with compilervars.sh. When compilervars.sh called ippvars.sh, it fails with the error: INSTALLDIR: no such file or directory The issue is with setting of IPPROOT: IPPROOT=/ipp Ii looks like the script doesn't know what to do with INSTALLDIR.  Was this suppose to be replaced with a pathway during install?  Does this mean the install was not done correctly? The other scripts called by compilervars.sh seem to have worked fine and the envornoment variables (i.e. MKLROOT) are being set correctly. I am using bash on RHEL5. Thanks in advance for any assistance you can provide.
