<div dir="ltr">Hi Users and Developers, I am trying to compile and build a CUDA build of CP2K and end up getting these annoying errors. dbcsr_types.f90(275): error #7747: Invalid parameter expression. [DBCSR_MEMTYPE_TYPE] TYPE(dbcsr_memtype_type), PARAMETER :: dbcsr_memtype_default = dbcsr_memtype_type(pool=Null()) -----------------------------------------------------------------^ dbcsr_types.f90(276): error #7747: Invalid parameter expression.

TYPE(dbcsr_memtype_type) :: memory_type = dbcsr_memtype_default Here is the ARCH (Linux-x86-64-cuda.sopt) file that I used.

It would be great, if there are any pointers that can help me to fix this issue. Appreciate your time and effort.
