Special Compiling Cases

This guide explains some of the less common ways to build Cantera

Intel Compilers

  • Before compiling Cantera, you may need to set up the appropriate environment variables for the Intel compiler suite, e.g.:

    source /opt/intel/bin/compilervars.sh intel64
  • For the Intel compiler to work with SCons, these environment variables need to be passed through SCons by using the command line option:

  • If you want to use the Intel MKL versions of BLAS and LAPACK, you will need to provide additional options. The following are typically correct on 64-bit Linux systems:

    blas_lapack_libs=mkl_rt blas_lapack_dir=$(MKLROOT)/lib/intel64

    Your final SCons call might then look something like:

    scons build env_vars=all CC=icc CXX=icpc FORTRAN=ifort blas_lapack_libs=mkl_rt blas_lapack_dir=$(MKLROOT)/lib/intel64
  • When installing Cantera after building with the Intel compiler, the normal method of using sudo to install Cantera to the system default directories will not work because sudo does not pass the environment variables needed by the Intel compiler. Instead, you will need to do something like:

    scons build ...
    sudo -s
    source /path/to/compilervars.sh intel64
    scons install

    Another option is to set the prefix option to a directory for which you have write permissions, and specify the USER value to the python_prefix or python3_prefix option.
