Windows 10: Store cross platforming

Hey.

If I buy a game on my laptop for $50 dollars, do I have to pay for it again to play the game with the same account on another device?
If it help, I'm wishing to buy Sea of Theives

Thanks.

:)

 

Minecraft cross platform

Is the cross platform now available for Minecraft windows ten and xbox one? if so is it as simple as putting minecraft on my computer and signing in with xbox live?

Moved from Windows / Windows 10 / Microsoft Store )

 

cross-platform play questions


I do not own an Xbox one or an Xbox 360, but my friend has an Xbox 360 and I have a windows 10 gaming PC. I was able to add him as a friend and send messages, but I see that a number of games do not show up in the windows 10 or Xbox one section of the store through the Xbox app or the windows store. So I have a couple of questions that I could not find any answers to through google.

First off, would a windows 10 PC be able to play games online with an Xbox 360 user?

Second, is it possible to do the cross-platform play if I do not own any Xbox consoles?

Third, will the steam versions of the game work for cross-platform play? Or must it be purchased through the Xbox app or windows store? (If through the Xbox app, then would I look in the Xbox one section or the windows 10 section?) [If through the windows 10 section in the Xbox app, would the Xbox one section games be playable if bought without the console?]

Fourth, If I am understanding correctly, older games (most on Xbox 360) will not work for the cross-platform play, and newer games (most, if not all on Xbox one) would work for cross-platform play?

fifth, regardless of my specific situation, would GTA: V work for cross-platform play with windows 10 to Xbox live players?

Thank you to anyone who takes their time to read and answer all my questions!

 

RPi2 from Windows cross compilation Error "The test for linking against libxcb failed!"

Error in Cross Compilation, I am using Qt5.0, Windows10, Raspberry Pi 2.
I was following this tutorial and the process failed at step 16 and tried with its suggestion but cannot find a solution.

Error prompted after step 16 is:

Running configuration tests...
The test for linking against libxcb failed!
Use of pkg-config is not enabled, maybe you want to pass -force-pkg-config?
You might need to install dependency packages for libxcb.
See src/plugins/platforms/xcb/README.

and when I printed log in file as tutorial suggested, there are some errors mentioned like:

• cc1plus.exe: error: unrecognized command line option '-fuse-ld=gold'
  
• error "Symbolic function binding on this architecture may be broken, disabling it (see QTBUG-36129)."
  
• etc.
  

I tried but still find no solution.
