Windows 10: one drive error symbol

In my PC shows One drive error symbol

:)

 

CD drive error

1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Control
Class
{4D36E965-E325-11CE-BFC1-08002BE10318}
4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

UpperFilters
LowerFilters
UpperFilters.bak
LowerFilters.bak
5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.

And it likely has something to do with the emulated drive you have listed there.

Hi Alex,

Virus and malware could be one of the possible reasons why you're having trouble with symbols on your keyboard. To isolate the issue, we'd like to ask you a few questions:

• Have you made any recent changes to your device before the issue started?
  
• Did you encounter any error messages while typing the symbols?
• Can you tell us the troubleshooting steps that you've performed?

Meanwhile, we suggest scanning your device using an antivirus program and see if it's infected by a virus.

We'll keep an eye out for your response.

 

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.
