I’ve been testing this alpha release on our codebase.
So far I’ve only encountered one problem inside SCons. In Scanner/__init__.py
When I use TryCompile() the header files are scanned and there is a problem if the header files can’t be converted to Unicode.
This triggered for me in boost-python where some of the header files have a corrupt character in the author’s name (German double-s I think). This leads to get_text_contents() returning bytes instead of str which causes the regex to fail. The fix is pretty straightforward:
Add
self.creb = re.compile(regex.encode(), re.M)
to have a bytes version of the regex, and then do:
def find_include_names(self, node):
text = node.get_text_contents()
if isinstance(text, bytes):
return self.creb.findall(text)
return self.cre.findall(text)
This allows me to build code that uses boost-python.
