Dear All,

I met a problem on installing VASP5.2.11. I use intel compiler and openmpi. Here are error information:

hessian.f90(24): error #6457: This derived type name has not been declared. [IN_STRUCT]
TYPE (in_struct) :: IO
---------------^
hessian.f90(51): error #6404: This name does not have a type, and must have an explicit type. [IO]
IF (IO%IU0>=0) write(*,*) 'HMAT has been reset!'
-------------^
hessian.f90(51): error #6460: This is not a field name that is defined in the encompassing structure. [IU0]
IF (IO%IU0>=0) write(*,*) 'HMAT has been reset!'
----------------^
compilation aborted for hessian.f90 (code 1)
make: *** [hessian.o] Error 1

Many thanks for your help!

Problem solved by adding "USE base".

Hi,

I'm getting the same error that you were getting. Where did you add "USE base"

Thank
