In qvfb of QT, compilation fails.

In qvfb of QT, compilation cannot be successful. for details, refer to Linux general technology-Linux programming and kernel information. I am downloading the embedded QT4.8.2. At this time, the entire embedded QT has not been edited. An error occurred while compiling the tool qvfb. (As shown below)
I have queried the file. there is no extensions folder or XTest. h header file.
How can this problem be solved? Thank you!
