Linking on IA-32 Architecture Systems

The following examples illustrate linking that uses Intel(R) compilers.
Most
 examples use the
.f
 Fortran source file. C/C++ users should instead specify a
.cpp
 (C++) or
.c
 (C) file and replace
ifort
 with
icc
.
In these examples,
MKLPATH=$MKLROOT/lib
/ia32
_lin
,
MKLINCLUDE=$MKLROOT/include
.
If you successfully completed the Scripts to Set Environment Variables Setting Environment Variables step of the Getting Started process, you can omit
-I$MKLINCLUDE
 in all the examples and omit
-L$MKLPATH
 in the examples for dynamic linking.
