Hello all

I compiled the VASP 5.3.3 with openmpi 1.2.9, ifort 9.1.052 and mkl 10.0.5.025 without problems. Now , I tried to compile the VASP 5.3.5 and got this message:

mpif90 -heap-arrays -I/opt/intel/mkl/10.0.5.025/include/fftw -FR -lowercase -O2 -ip -c chi_base.f90
fortcom: Error: chi_base.f90, line 2606: Error in opening the compiled module file. Check INCLUDE paths. [ISO_C_BINDING]

compilation aborted for chi_base.f90 (code 1)
make: *** [chi_base.o] Error 1

Any idea?

Thank in advance

VASP 5.3.5 uses the intrinsic module ISO_C_BINDING .
To compile the code you need newer compiler.
When using intel/composer_xe_2011_sp1.11.339
the error is not reproduced.

The problem might be related to the fact that chi_base.F contains (twice) the instruction
USE mpi
instead of
USE mpimy
that is present in all other .F files. I suspect this is a bug
