Error using compilervars.csh or ippvars.csh - arch: Undefined variable.

A defect was reported with the Intel® Integrated Performance Primitives (IPP) 8.1 Initial release ippvars.csh file distributed for Linux* (found under: /opt/intel/composer_xe_2013_sp1/ipp).

OS X 10.9 Xcode 5 error can't open "stdlib.h" OR ld: library not found for -lcrt1.10.6.o

Environment:  OS X 10.9 (Mavericks) and Xcode 5.0

Command line compilations/links fail with either:

"catastrophic error: cannot open source file "stdlib.h" OR with "ld: library not found for -lcrt1.10.6.o"

Affected compiler:  Intel Composer XE 2013 Update 1

Root cause:  Xcode 5.0 installation does not install all command line tools (include files, libraries, SDKs) need for the compiler to link user applications.

autoparallelization problem

When I compile the following small program with -O2 or -O3 and -parallel and run it with OMP_NUM_THREADS>1 it crashes with signal 11 either immedeately (-O2) or when trying to print out res (-O3). Running the parallel binary with OMP_NUM_THREADS=1 does work. When the last printf statement is commented out, the program will run with more than one thread if compiled with -O3 -parallel.

running icl from command line

Guys, I know intel's compiler needs VS in order to work. I have VS2013 Pro installed.

I need to run icl (your compiler) from command line. 

I've tried to run it by simply going into directory and typing icl [pathTo]main.cpp but I'm getting error:

icl: error: #10114 Microsoft Visual C++ not found in the path.

How to pass path to visual studio to icl from the command line?

Thank you.
