Trouble with playing videos in green_shoes gem

Question

Here's my problem. I've tried video example from greenshoes samples. But I can't run it because of this:

require': cannot load such file -- win32api (LoadError)

So this gives me a message that I have to install win32api gem. I've tried to install win32api with this:

gem install win32-api

But it gives me this message:

Building native extensions.  This could take a while...

ERROR: Error installing win32-api: ERROR: Failed to build gem native extension.

Here's the part of backtrace:

Did you succeed in installing gstreamer stackoverflow.com/questions/25158867/… ? If so, what did you do? This error seems to be closely related to gstreamer. I can't get this running either (in Fedora Linux, but my error is LoadError: cannot load such file -- gst) so I don't think I will be able to help you any further. — dcorking
It is not an answer, but you could experiment with why's Shoes: shoesrb.com In contrast with green_shoes, Shoes::Video relies on different video libraries: videolan and ffmpeg , which tend to be well supported in Linux and might bring you more luck. shoesrb.com/manual/Video.html — dcorking
Please post the stack trace that was printed with the LoadError. This may help someone to track down which ruby file is trying to use win32_api and why. — dcorking
I've already fixed my gstreamer problem. stackoverflow.com/questions/25158867/… — Milos Dolobac
(I guess ordinary green_shoes programs work for you, but I'll ask just in case.) — dcorking

The message fatal error: windows.h: No such file or directory means that your C compiler cannot find your Windows SDK, and in particular the windows.h header file.

If you have that header file, you need to fix your C compiler's configuration.

If not, you need to obtain the Windows SDK.

windows.h is in several places in Debian-derived GNU/Linux distributions. One such place is the mingw-w64-i686-dev package, but I don't know which package, if any, you need to run green_shoes video.
