 This ticket is about cross-compiling, #13694 is about native builds (using
 mingw).

Comment:

 We discussed this documentation in the network team meeting.

 We want to document the following use cases:
 * cross-compiling Tor (Tor Browser, Tor Devs using Wine)
 * compiling Tor using mingw (Appveyor, Tor Devs using Native Windows)

 We want to spend some more time reviewing this document, and trying out
 the process, before deciding if we want to merge it as-is, or make some
 more changes.

 Didn't exist when I wrote this :)

 I'm virtually certain that they don't.

 Should be, I forgot about MSYS2. Also I'm not sure if their packages are
 usable for cross-compiling.

 Sounds good.

 I think that was a worse option when I wrote this, but sure.

 For non-Debian users.

 I didn't know ahf had instructions.

 I don't understand why we get cross-compiled libraries from Jenkins, when
 we can just get signed libraries from Debian. I also think that ahf's

 Is there a reason you rewrote/summarised them?

Comment:

 This documentation seems ok to me.

 But I am not sure that the references to compiling on Windows are
 accurate:

 > Compiling tor *on* Windows using mingw is theoretically supported, but
 few
 > developers actually use this configuration, and it is not used to build
 Tor
 > Browser. Therefore, this guide will only cover cross-compilation.

 We compile tor on Windows using MSYS2 on every pull request on 0.3.4 and
 later:
 https://ci.appveyor.com/project/torproject/tor

 MSYS2 contains cygwin as well as mingw. The library and compiler names
 suggest that our builds just use mingw. But I haven't checked if the
 builds or binaries depend on cygwin.

 > 2. Acquire libevent, openssl, and zlib cross-compiled for mingw. ...

 MSYS2 has package repositories containing these libraries. There seem to
 be versions of the libraries that just depend on mingw.

 Once this cross-compiling document is accurate, we should merge it.
 Then we can open tickets for mingw-on-Windows and MXE builds.

 Thanks. Please delete mentions of MXE for now. We can look at that in a
 separate ticket. Also, what do you mean by this:
 > Jenkins is not a part of the Tor infrastructure

Comment:

 Thanks for the new documentation!

 I'm not sure the core team has much experience with MXE or much interest
 in trying it out.  Please delete the MXE section for now.  Feel free to
 submit it under a separate ticket.

 `RUST_TARGET` should be `TOR_RUST_TARGET`.  We changed it to reduce
 chances of environment variable conflicts.

 Please don't refer to yourself as "this author" in a shared-authorship
 document.  Also I'm not sure we should be making such claims about the
 security properties of using the Jenkins build artifacts.  I think it's a
 tradeoff, and maybe one that we shouldn't try to summarize here.  Maybe
 it's enough to mention that the artifacts aren't signed and their
 integrity depends on the Jenkins infrastructure itself and the web CA
 infrastructure.
