Compilation flags are invalid on OS X

[Charlie_X]

As long as libxml2 and libxslt are around (installed by MacPorts or Homebrew) then lxml installs fine on MacOS X.

However, building from source is another matter. There seems to be a problem disabling the optimisation flags leading to errors like: 'error: invalid integral value '0 -g' error: command '/usr/bin/clang' failed with exit status 1`

Commenting out the line that sets these flags "solves" the problem. I assume this is due to a slight difference between clang and gcc.

This was tested with lxml 3.4.0 on OS X 10.10 (Mavericks) with Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)

what line is that? and does it help to reverse the flags into "-g -O0" instead of "-O0 -g" (which I assume you're using)?

It's from the standard tox configuration. Changing it as you suggest does resolve the problem. Do we need to add a check for clang?

No, if the order is a problem, I can just change it:

Fixed in lxml 3.4.1.
