compiling c++ program with intel compiler icpc in linux

Question

I have installed intel compiler Intel® Parallel Studio XE 2015 and I have written simple hello world program at desktop.

then I can't figure how can I run this cpp file.

I have tried as

icpc helloworld.cpp

but it says command not found.

Answer 1

You need to have icpc in your PATH. If you do know where Intel compiler is installed then append the PATH env variable. If you don't, search for icpc binary.

~> find / -name icpc
/opt/intel/composer_xe_2013_sp1.0.040/bin/intel64/icpc

Once you've found it, a convenient way of changing your environment is to source a script which comes with the compiler.

~> source /opt/intel/composer_xe_2013_sp1.0.040/bin/compilervars.sh intel64
~> which icpc
/opt/intel/composer_xe_2013_sp1.0.040/bin/intel64/icpc

This adding-to-path procedure is explained on Intel website here.
