Hypervolume compile error again. #244
Comments

Is your python aware of your gcc? |
|
So it seems to be a bigger issue with python 3.6 not being compatible with mingw. Installing MSVC 14 (2015) and installing through the c++ command prompt works for compiling and geting rid of this error. Maybe there should be a note regarding python/compiler versions and incompatibilities that exist. |

@PaoloBenigni i'm running into the same problem, with the exact same setup as yours (afaics). i have NOT tried your MSVC14 solution yet, but but i have a bit more logging. upon running any idea what could trigger that gcc error? |
|
Yes, the problem is that ming32 is not compatible with python 3.6, so you have to replace it with mscv2014. I dont recall having to specify the compiler on windows, if its in your PATH correctly it should work. |
|
ah, works now, thx! |

The solution in #240 did not work. Using Windows 10/Python 3.6.6/pip (not conda). pip install --upgrade --upgrade-strategy "eager" --force-reinstall --ignore-installed --compile --process-dependency-links --no-binary :all: deap Error:

Do you have a compiler in your path?

Can you please elaborate which compiler (I'm on Windows 10 64bit) and if there is a way to verify that the path is working? Installed VS 2017 community. before had just MS Visual C++ 2017 redistributeable installed. Tried the following:
Still getting the same error when running |

Do you have Microsoft visual studio installed?

Yes, I detailed above that I installed it and tried again. Again, would you please elaborate a bit more what is required and a quick way to verify that it works? |

Here would be the steps to ensure you have a proper compiler on your path.
Ensure you have the C++ toolset installed.

Is there a how-to link that explains the steps to accomplish this?

Worked! I had some VS 2017 components missing. Added them according to the link and reran the command above! I noted the following a few times. Thanks you! |

The warning is sklearn, not deap :). Glad it worked! |
My windows 10 running py 3.6 is having issues compiling hypervolume. I cant seem to find the error.
Here is a copy of the verbose output when following the recommendation in #240. Mingw is in path, gcc -- version reads 6.3.0
