Unless you don't have Intel's MKL installed (it is usually distributed now with ICC), or have some other good reason to use the slower reference Lapack sources from Netlib, the following will be simpler:
Remove the '#include ' line
Replace '' by ''
Compile with the command
icc -mkl lapacktest.cpp
You may now run the a.out, and your second greeting (after 'hello world!') will be a Segmentation fault, since you are calling cgeev_ with all NULL arguments.
