Hello Kazik,

When you enter the comand :
make libem64t complex_3d_double_ex1, 
It will rebuild libfftw3xc_intel.a to current directory.
But from the error message : mkdir: cannot create directory `/local/intel/Compiler/11.0/081/mkl/examples/fftw3xc/lib': Read-only file system ,
looks you haven't write right with the directory?  Could you please check it and add write if possible?

Regarding icpc problem, icpc is supposed for c++ file. Since dfti_example_support.c complex_3d_double_ex1.c are c language, you may use icc to build them for example.

icc  -I/opt/intel/Compiler/11.0/083/mkl/include/fftw   source/complex_3d_double_ex1.c source/dfti_example_support.c -L./lib/em64t -lfftw3xc_intel -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -o complex_3d_double_ex1


You mentioned g++ can work? do you use special compiler option when build the complex_3d_double_ex1.c ?
(my test show g++ show many compiler error too, where if use gcc, the compile processing is ok).


Best Regards,
Ying
