C++ Compiler error

[ScottShingler]

I'm trying to install lz4 using pip install lz4, but I get the following error:

I'm running Python 2.7 and have the matching Microsoft Visual C++ Compiler for Python 2.7 installed. Is this lz4 package not compatible with Python 2.7?

[darkdragn]

No, this doesn't have anything to do with python. The C++ compiler for your system doesn't like the /W switch without an argument, which setup.py is throwing in. I'll just throw in a test for microsoft and have it change the compiler flags for your system. Not sure if I'll get to it tonight though, and I'm terribly sorry I didn't get to this sooner.

V/R, Chris

[darkdragn]

That compiler string was mainly a holdover from another project. I just removed the blank -W switch, and left the others. I know you haven't even looked at this in a while, but if by some slight of fate, you get this message, please give it another try. Tomorrow, I'll kick up an old windows VM and give it a try as well.

What is the status of this issue?

I think simple including -W only on non-Windows system should fix this issue.
