this option has not worked since gcc 3 and is an error since 4.5ish

Ah, good to know. Fixed.

I have a first draft of the documentation put together now in this PR. I tried to be somewhat more general compared to the old version given how much active development is going on currently. If there is anything missing or inaccurate, please let me know! |

this will install cygwin linked versions of openblas which work well with cygwin's python but probably not python.org native python
edit: this should be one line lower, sorry

No worries and fair point.

@tkelman : I made your suggested changes. If there is anything else that needs to be changed or is inaccurate, do let me know! |

This links to the 'Visual C++ redistributable package', which is not enough to build yourself

Does anyone else have anything to add to this at the moment? Otherwise, it seems like it can be merged. |

So on Windows it doesn't need icc, like it does on Linux? That's probably worth mentioning explicitly.

No AFAICT. Based off the log, my builds use cl.exe from Visual Studio. I will add a comment to make it clear that icc is not strictly necessary.

Other than my nitpicks LGTM |

@Eric89GXL : Updated PR with your comments. If no one else has anything to add, I think this is good to merge. |

Thanks @gfyoung |

@Eric89GXL : Thanks! Are you able to upload the changes to the website? I still see the original documentation. |
|
I haven't done that before, so I'm not sure what the procedure is. |

Not to worry. Somebody already did it. I believe the command is |
