| How did you build Python 3.6 on Windows? Did you use Visual Studio 2015? Do you use Visual Studio GUI or in the command line? |

| I have installed Visual Studio 2017 and have ran PCbuild\build.bat. From the master branch all have built successfully. |

| I believe that's the case, although I'm somewhat surprised by the nature of the error. I'm just checking diffs at the moment. But VS 2015 is the officially supported compiler for 3.6. |

| > https://haypo-notes.readthedocs.io/cpython_windows.html#python-and-visual-studio-version-matrix Thank you Victor. Therefore I do need to install 4 versions of Visual Studio for building three major maintained branches: 2008, 2010, 2015 and 2017? Oh, now I understand why Victor doesn't have sufficient disk space for running tests. |

| To compile Python 2.7, you need VS 2008 *and* 2010. To compile Python 3.5, 3.6 or master, you need VS 2015. To compile Python 3.4, you need VS 2010. I had to work on Python 2.7, 3.4, 3.5, 3.6 and master, so I installed VS 2008, 2010 and 2015 :-) I didn't give a try to VS 2017 yet. I'm fine with 3 VS versions installed in parallel ;-) |

| If you install VS 2017 and select the "Python native development" option as described in the dev guide, you get the correct compilers (plural) for Python 3.5 onwards. The build.bat file (specifically, the find_msbuild.bat helper) will choose the correct version. You do not need to install VS 2015 anymore. VS 2015 and VS 2017 both include VC toolset v140, which is the officially supported compiler (the VS version is separate). The error is coming from the Tcl makefile at these lines: .SUFFIXES: .SUFFIXES:.c .rc I personally have no idea what these mean or why it is failing, and I don't even know what these are meant to do. But perhaps you have some file called ".SUFFIXES" or similar that is causing the Tcl build to fail? |
