How to compile AtChem2

AtChem2 is compiled with the script build.sh, located in the tools/ directory. Depending on the version of AtChem2, the build.sh script takes 3 or 4 positional arguments (i.e., the arguments must be provided in a precise order).

version 1.2

build.sh has 3 positional arguments:

1. path to the chemical mechanism file (.fac)
2. path to the model configuration directory - default: model/configuration/
3. path to the MCM data files directory - default: mcm/

./tools/build.sh ./model/mechanism.fac ./model/configuration/ ./mcm/

version 1.1.*

build.sh has 4 positional arguments:

1. path to the chemical mechanism file (.fac)
2. path to the auto-generated Fortran files directory - default: src/gen/
3. path to the model configuration directory - default: model/configuration/
4. path to the MCM data files directory - default: mcm/

./tools/build.sh ./model/mechanism.fac ./src/gen/ ./model/configuration/ ./mcm/

version 1.0 and earlier

build.sh has 3 positional arguments:

1. path to the chemical mechanism file (.fac)
2. path to the Fortran source files directory - default: src/
3. path to the model configuration directory - default: modelConfiguration/

./tools/build.sh ./mechanism.fac ./src/ ./modelConfiguration/
