# MLNLFFIGen

mlnlffigen generates a MLNLFFI binding from a collection of .c files. It is based on the CKitLibrary, which is primarily designed to handle standardized C and thus does not understand many (any?) compiler extensions; however, it attempts to recover from errors when seeing unrecognized definitions.

In order to work around common gcc extensions, it may be useful to add -cppopt options to the command line; for example -cppopt '-D__extension__' may be occasionally useful. Fortunately, most portable libraries largely avoid the use of these types of extensions in header files.

mlnlffigen will normally not generate bindings for #included files; see -match and -allSU if this is desirable.
