Intel C++ 10.0 for linux
Get the most out of it
I like gcc very much but now I have a Intel Core 2 Duo notebook, and I think it’s time to get the most out of it. That’s why I go for the Intel C++ 10.0 compiler today.
Intel provides a “free for non-commercial usage” download, that’s pretty nice and one more reason to give’em a try!
The other thing I am really interested in is the openMP integration. If you had troubles with pthreads you know why!
Start of my report
Go to the download page, confirm non-commercial agreement, register with email address, then start downloading the 45 MB package (in the IA32 version).
Untar the package and as root type
./install.sh
The installation went smooth, had to agree to several license agreements, answer some question (always took the default). Until suddenly:
Your platform :
architecture = i686
kernel = 2.6.18
glibc = glibc-2.5-25
operating system = unknown
This product is supported for use with the following combinations :
Machine Type Kernel glibc
IA-32/Intel(R) 64 2.4.x 2.2.5
IA-32/Intel(R) 64 2.4.x 2.2.93
IA-32/Intel(R) 64 2.4.x 2.3.2
IA-32/Intel(R) 64 2.6.x 2.3.x
IA-32/Intel(R) 64 2.6.x 2.4.x
IA-32/Intel(R) 64 2.6.x 2.5.x
Would you like to perform an unsupported install of this product [yes/no] (no) ? :
At this point I face my fear but typed YES.
After some other questions (always answer with default) I finally got the “successful” message:
Successfully installed:

First compilation
My first compilation will be a “Hello World” as it is good tradition in the C business:
#include <stdio.h>
int main(int argc, char **argv)
{
fprintf(stdout, "Hello ICC Worldn");
return 0;
}
To get the icc environment up, Intel delivers a Shell-Script. Source it then compile like this:
source /opt/intel/cc/10.0.023/bin/iccvars.sh
icc hello.c
Then run the result:
./a.out
Watch the output and be happy 
Hello ICC World
This is so great! Tomorrow I’ll report on first experiences with openMP!
See you soon!
