Build fails on Windows/MSYS2

[nesteruk]

Your Windows build instructions are out of date. First of all, the set of commands doesn't install GCC, so that has to be done separately. But even after that, there are plenty of issues that prevent compilation.

Please verify compilation on Windows and update the build instructions accordingly.

GCC is mingw-w64-x86_64-gcc, which is contained in the mingw-w64-x86_64-toolchain group, so it will be installed if you follow the instructions. Can you be a bit more specific? What exactly is the error you're getting?

[petrochenkov]

Sounds like you are trying to build it from "MSYS2 Shell" and not "MinGW-w64 Win64 Shell"

[nesteruk]

Yes, I'm building from the MSYS2 shell. Will try the mingw shell now.

Here is the output I'm getting

Are you actually building inside your Dropbox folder? If so it's likely that googledrivesync.exe is interfering files as the build process is attempting to modify them. Antivirus software can also do this.

[nesteruk]

No, that's definitely not it - I tried taking the files out of the folder. Also, googledrivesync, that has nothing to do with dropbox.

[mingwandroid]

Yeah, I needed more caffeine when I wrote googledrivesync, obviously I meant the dropbox client.

I'm trying to build rust with 64bit MSYS2 on Windows10 with the steps described in README.MD (installing a separate MinGW GCC 4.9 based toolchain). However MinGW cannot be installed right now, since the installer fails to download repositories.txt (this bug reappers from time to time, the last instance is here: https://sourceforge.net/p/mingw-w64/bugs/528/)

Is there any way to get around it? Maybe using the mingw-get utility which works? Which packages should i choose in mingw-get to get the same environment? Or what about using Cygwin which is known to have a more stable installer? I'm using it's derivate called Babun daily in my work and I'm really satisfied with it.

(Just as a side note, I've tried downloading compiler suites from http://www.drangon.org/mingw/ but I'm getting various errors with that way too, and I'm not so experienced with GNU toolset compiling to know exactly if it's not my error. Also i like to stay with the GNU way since i would like to build rust in the end with --target=arm-unknown-linux-gnueabi using the Linaro ARM Windos toolchain in place).

Build instructions for Windows were rewritten several times and the old build system is removed.
Please, open a new issue if something suspicious still happens.
