Oh, this is awesome! Thanks for the report.

@AlbertMoscow, how have you compiled Elixir on Windows? Doesn't it require make to run all the Makefile commands?

[alexrp]

Last I checked, you can build Elixir in a MinGW shell.

[AlbertMoscow]

@josevalim, that's right! I used MinGW shell with MSYS installed when was trying to compile Elixir on Windows.

http://www.mingw.org/wiki/MSYS

http://www.mingw.org/wiki/Getting_Started

http://sourceforge.net/projects/mingw/files/Installer/mingw-get-inst/

One should never forget to add to his or her Path:

;C:\MinGW\bin;C:\MinGW\msys\1.0\bin

and restart the computer. :)

[josevalim]

Thanks @AlbertMoscow! I have fixed a couple of those but I don't have a Windows machine set up. Would you be interested in helping us getting our suite green on Windows? I am making myself available for any kind of help you may need on this task. :)

[AlbertMoscow]

@josevalim, of course! Do you mean testing your fixes on my Windows machine, don't you?

[josevalim]

@AlbertMoscow I mean by testing my fixes and helping us investigating and fixing the other ones. :)

[AlbertMoscow]

@josevalim, I believe we understood each other! :)

[AlbertMoscow]

José, are your fixes in master branch? I'd like to test them.

[josevalim]

In the master branch, yes.

[AlbertMoscow]

Great news! There are two books awaiting for Elixir 1.0 to come out by the end of this year, so you guys have whole six months to fix all 46 remaining failures in 1074 tests on Windows. :)

[josevalim]

And with our community growing every day, hopefully many developers will help us tackle this task by sending lovely pull requests! :D ❤️ 💚 💙 💛 💜

@AlbertMoscow I also have mingw etc, and eveything in the path, but somehow I get the following error:

Any tips/pointers/... ?

[josevalim]

All, you need to run make compile and make test. Please don't use mix to compile elixir as it runs into bootstrapping issues! :D

[ToJans]

Tried with make, other error:
