Hi Gary,
The most effective thing you can do to reduce the installed size is to disable the debug symbols that are normally kept in the compiled Cantera code by setting the SCons option debug=n. You can disable the Fortran and Matlab interfaces with the f90_interface=n and matlab_toolbox=n options, respectively. To work with CTI files, you only need the “minimal” Python module, which just includes the scripts for converting mechanisms. You can specify this with the option python_package=minimal. Or if you can convert your mechanisms to YAML on another computer, you can skip the Python module entirely by setting python_package=n.
There is no option to omit the reactor / flame solvers, but I don’t think that would actually reduce the size very much. At least on my system, the first change, disabling the debug symbols, decreases the size of the static library (libcantera.a) by an order of magnitude, from 167 MB to 16 MB.
Regards,
Ray
