mix deps.compile fails on Windows

[ToJans]

After I cloned the dynamo-repo, I tried to compile everthing, but it fails on windows; this is the output:

 C:\dev\MELF\elixir\dynamo>mix deps.compile
 * Compiling mimetypes
 ** (Mix) could not find executable c:/dev/MELF/elixir/dynamo/deps/mimetypes/rebar to compile dependency mimetypes, please ensure c:/dev/MELF/elixir/dynamo/deps/mimetypes/rebar is available

I think this has to do with the fact that on windows the "rebar" file is not executable; we have to invoke rebar.cmd instead.

@ToJans which Elixir version are you running?

[ToJans]

 C:\dev\MELF\elixir\dynamo>iex -v
 Elixir 0.9.0
 Interactive Elixir (0.9.0) - press Ctrl+C to exit (type h() ENTER for help)
 iex(1)> Batchopdracht beëindigen (J/N)?
 ^C

FYI rebar.cmd (which is used on windows) is in my path, this is the version

 C:\dev\MELF\elixir\dynamo>rebar -V
 rebar version: 2 date: 20120417_234834 vcs: git afffb48

So some kind of a fallback on windows where rebar is called without a path would be perfect for me....

Upgraded elixir, still the same; FYI:

C:\dev\MELF\elixir\dynamo>iex -v
Elixir 0.9.1
Interactive Elixir (0.9.1) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> Batchopdracht beëindigen (J/N)? j

C:\dev\MELF\elixir\dynamo>mix deps.compile

@ToJans I have pushed a new precompiled package with master that theoretically solves this issue, could you give it a try?

[ToJans]

@josevalim thanks for the quick fix!
Installed & it compiles the mimetypes library perfectly.

It fails on ranch, but that is probably because I do not have "make" in my path. I will try to fix this and get back to you...

[josevalim]

Great! If we can compile mimetypes, mission accomplished. :) Now, getting make to work on windows is another story... if you find out a way, pls let us know!

[ToJans]

@josevalim I got it working with MinGW minimal system; I keep getting compilation errors, but it seems to work:

FYI I have written a small blog post a few days ago on how to get started with Elixir/dynamo on Windows.

I also can't mix deps.compile for dynamo on Windows. Elixir version is 0.9.4-dev. And I have rebar 2.1.0 installed.

[josevalim]

It is a bug on the mimetypes lib that is choking on a \r, so it can't parse the mimetypes file. We should fix it on the mimetypes lib by improving the parser or not allowing CRLF changes when checking out on windows :) /cc @yrashk
