Makefile:6: *** missing separator (did you mean TAB instead of 8 spaces?). Stop

I did a diff between my makefile.intel and yours, and another difference is that you have switched the compiler to use gcc and the gcc compiler flags.

Please see the following issue for flags that can be used successfully with gcc for this program:

How to set flag options of MEGANv3.2 Makefiles in accordance with the gfortran compiler?

Hi, I’m new to biogenic emission modeling, and I’m trying to use the gfortran compiler to build and run the MEGANv3.2 model. I got an error when running “make_all_programs.scr”. I don’t know how to set the flag options of the Makefiles (under DAYMET, IOAPI2UAM, MEGCAN, MEGSEA, MEGVEA, MET2MGN, MGN2MECH, TXT2IOAPI) in accordance with the gfortran compiler. Could anyone help me to set the suitable flag options for the Makefiles? Thank you for any help in advance. Reza [image]

I’ve also attached the makefile that worked for the gcc compiler here.
