Other Info

The above is only the bottom several lines of the error output, the actual output is over a thousand lines of similar errors. I'm not sure why these errors are occurring, as far as I know there is nothing wrong with my MinGW installation. This issue may still be on my side. If so, any help would be greatly appreciated.

@olekukonko I do not see how this could possibly be related to my issue.

From what I have looked at a big part of my issue must be related to the preprocessor. But how to fix it, or if it's fixable, is beyond my knowledge.

@drako0812 its a bit related ... am still doing some investigation on the issue, but this is the more reason why Terminal progress bar for Go should not depend on it for such a simple task ... so many other things not relating to screen size can make it fail

[drako0812]

I managed to hack user32.go in a way that allowed w32 to build on my system.

The original was:

import (
  // #include <wtypes.h>
  // #include <winable.h>
  "C"
  "fmt"
  "syscall"
  "unsafe"
)

The modified version:

import (
  // #include <windows.h>
  "C"
  "fmt"
  "syscall"
  "unsafe"
)

I'm not entirely sure why this worked except that some sort of preprocessor defines were affected.

If you using windows 64-bit then you need download go for amd64 architecture.
