Using the same instance mentioned in #101 , the output file header lines contains following content

# WORD_SIZE is: 8
# POINTER_SIZE is: 8
# LONGDOUBLE_SIZE is: 16

Should I worry to set these parameters properly before executing clang2py? If yes, how? Thanks for any hint.

Already figured this out. The target needs to be customized according to the specific hardware setup.

  -t TARGET, --target TARGET
                        target architecture (default: x86_64-Linux)
