[Request for install] MinGW W64

Hello,

Currently, the images have the "legacy" (old & unmaintained) mingw project. However, mingw-w64, is a fork of mingw, which is maintained. Could we have that instead/besides the legacy mingw? It would help a lot to not have to manually install it everytime.

The only "issue" is that there are two "variants" of threading: posix & win32. But we could have the two possible installed in different directories, so we can just chose whichever we want.

How does that sound?

    What about MSYS2? Is it not the same?

    Well, not really. MSYS2 is Cygwin-based, but MinGW (and MinGW-W64, by
    definition is native to Windows)

    OK, I presume we need mingw-w64 then with "win32" flavor? Can you drop a URL with download and installation instructions please?

    It can be quickly installed by chocolatey:

    |choco install mingw
    |

    |and|

    |choco install mingw --x86
    |

    |There will install mingw in:
    |

    |* C:\tools\mingw32|

    |* C:\tools\mingw64
    |

    There are also numerous mingw installations inside C:\Qt folder, for example: C:\Qt\5.6\mingw49_32

    I would suggest the 32 and 64 bit flavors of tdm-gcc,
    but i'm not sure about the "variants" of threading it supports.

    http://tdm-gcc.tdragon.net/download

    Sadly, the tdm-gcc installer executable doesn't support silent or automated installs.
    A pre-installation on Appveyor would be really helpful.
    Normally i install with type "MinGW stable, C++" and zip the install folder to make it portable.

    I would like to upvote the request to pre-install MinGW 32 and 64 through their chocolatey packages.

    I am trying to run an extensive matrix (all architectures, all compilers, statically and dynamically linked) and these packages work fine but take time and create stochastic 404 failures when they are being installed.

    Would you need all "thread" and "exception" permutations for both 64- and 32-bit versions?

    Nah - the vanilla versions installed using choco (as mentioned above by Timotei) are working fine for me.
    IMHO doing combinations on libraries would be beyond the limit of keeping things reasonable.

    BTW. You can't regularly install both 64 and 32 bit versions on a single system, as they are two flavors of the same package for choco. This will requires manual copying both into to same image or making choco force-install the second flavor.

    By "flavors" do you mean 64- and 32-bit versions? It's not an issue to install all flavors without Chocolatey. What command do you use to install mingw with Chocolatey?

    Yes, I mean the 32 vs. 64 bit versions.

    With Chocolatey I am using
        cinst mingw
    for the 64 bit version, and
        cinst mingw --x86
    to force installing the 32bit version.

    This will install in the places Timotei mentioned.
