why generate a Makefile with Fortran77 instead of Fortran90 for one mechanism in KPP

[Lily_Zh]

Hi,

I begin to learn to modify wrfchem code and copy one mechanism in KPP to be a new one. I don't know how it can generate a Makefile_mechanism name with the first line--
# Set here the Fortran77 compiler and the desired optimization options

I saw others with the line
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# User: Set here the F90 compiler and options
# Pedefined compilers: INTEL, PGF, HPUX, LAHEY

When I compile model, it can not find the mecahnism with .f90, because only .f generate there.

I am thankful for any idea about this.

Thank you in advance.

Lily

Solved it, I need to keep consistent format strictly in .eqn and .spc files
