Windows 10: Phone Link Error

I'm having trouble with Phone Link. I go through the pairing process and it seems to work on the phone but not the computer. It will give me a failed screen. If I close that window, a new Phone Link will populate, saying my phone is connected but the bluetooth needs to be repaired. When you click Begin Repair, it takes you to a screen that shows my device but doesn't let you do anything but remove it. I have tried unpairing, forgetting device, all of that. And my bluetooth isn't the issue because I have bluetooth headphones connected fine. Any advice?Phone Link Error Part 1Phone Link Error Par

Supported phones for Windows 10 Mobile Insider Preview Mobile

Your list confirms my phone is eligible, Lumia 521. The windows Insider App fails after ~ 15 seconds, restores data and gives me error 80073cf9. I trouble shot this and went thru all the steps mentioned on several websites including MS without any luck. Short of a hard reset, this is where I am now. Suggestions appreciated.

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.
