I'm trying to use the distutil compiler to preprocess some header (to be used with the cffi package).
The code is
compiler = distutils.ccompiler.new_compiler()
compiler.add_include_dir(join(sys.prefix, 'include'))
compiler.preprocess(source)
This raises this exception (on Linux):
File ".../distutils/unixccompiler.py", line 88, in preprocess
pp_args = self.preprocessor + pp_opts
TypeError: unsupported operand type(s) for +: 'NoneType' and 'list'
caused by 'set.preprocessor' to be set to None (with the preceding comment:
# The defaults here
# are pretty generic; they will probably have to be set by an outsider
# (eg. using information discovered by the sysconfig about building
# Python extensions).
Seems that code never got fully implemented.
Further, the MSVC version of the compiler (msvccompiler.py) doesn't even implement a "preprocess()" method, so this falls back to the CCompiler.preprocess() default, which does nothing !

Distutils does not evolve anymore — if CFFI still needs something like this, I think it should build on setuptools and request features there. |
