Compile error on MSYS2 64 bit

[jhasse]

I'm running latest Rust and Cargo through a MSYS2 mingw64 shell. When trying to compile my program I get this error:

~/git/rust-opengl-test (master %=) cargo run
   Compiling rust-opengl-test v0.1.0 (file:///C:/msys64/home/jhasse/git/rust-opengl-test)

error: aborting due to previous error
Could not compile `rust-opengl-test`.

To learn more, run the command again with --verbose.

The strange thing is, when I copy the build command and paste it into the shell, it compiles just fine and also the resulting .exe file works. Running with --verbose doesn't give any more information. What could cause this?

Hm interesting! The windows bots have been sporadically failing for a very similar problem. I've been quite curious as to why, and unable to ever replicate it!

Is this repository somewhere that I could play around with? Do I need to install any prerequisites to get it working?

It's here: https://github.com/jhasse/rust-opengl-test

You need to edit ~/.cargo/git/checkouts/glfw-4fd4342c6777c12d/cargo-3.0.4/makefile.cargo: Quote the variables and add -G "MSYS Makefiles" to the cmake command (the latter is a "bug" of MSYS2 which some people have discussed on the mailing list some time ago. I might bring that up again and hope I can fix it in MSYS2's cmake or upstream).

Sadly this is rust-lang/rust#17442, not the error I was looking for :(

[jhasse]

I see. Thanks for looking into this :)
