Overview

GEOS-Chem and GCHP use two build systems to compile source code files into an executable file:

  1. GNU Make
  2. CMake

At present, both GEOS-Chem "Classic" and GCHP use GNU Make. CMake will soon replace GNU Make in both GEOS-Chem "Classic" and GCHP.

Which versions can use GNU Make and which can use CMake?

GEOS-Chem "Classic" compatibility matrix

Some GEOS-Chem "Classic" versions are compatible with both CMake and GNU Make, as shown below.

GEOS-Chem "Classic" version Uses GNU Make? Uses CMake?
12.5.0 and prior YES NO
12.6.* YES YES
12.7.* YES YES
12.8.* YES YES
12.9.* YES YES
13.0.0 (release TBD) and later NO YES

GCHP compatibility matrix

Unlike GEOS-Chem "Classic", GCHP will have a "hard" transition from GNU Make to CMake in 13.0.0:

GCHP version Uses GNU Make? Uses CMake?
12.5.0 and prior YES NO
12.6.* YES NO
12.7.* YES NO
12.8.* YES NO
12.9.* YES NO
