Hi and welcome to devnet,

Please don't highjack other people thread with completely unrelated questions. I've created one for your question.

From your error it looks like you don't have the OpenGL development package for your distribution installed.

Also note that Qt 5.2.0 is pretty outdated, the current version is 5.8.0.

One last thing, developing as root is really a bad idea, if you do anything wrong, there won't be any warning or stopping measure so you can brick your system pretty easily.

thanks i come from china ，build qt just 2 days

@The-most-recent-future Do you have to use this old Qt version?
Current version is 5.8

[The most recent future]

@jsulm
yes. version 5.2.0
but , the error ................ can you help me??

[jsulm]

@The-most-recent-future Do you build for desktop or for a device?
Also as @SGaist said you should really not develop as root - this is a very very bad idea.

[SGaist]

What exact options did you pass to configure before building Qt ?

[The most recent future]

@SGaist
./configure
-release

-qt-libpng
-qt-zlib
-qt-libjpeg

[SGaist]

There: -no-opengl. I remember there where some problem at some point building with -no-opengl, it should have been fixed in between but I don't remember if it was prior to or after Qt 5.2.0

[The most recent future]

@SGaist
Whether or not to add
-no-egl
-no-opengl

these error will be show !

@SGaist 大神，就我！！

[The most recent future]

@SGaist
这个问题困扰了我好几天了，大神，你救救我吧！我都要哭了....

[SGaist]

When changing the configure options, are you doing from a clean source ? That's the first thing to do before calling configure again.

Or better: do out of source builds, so if something goes wrong, you juste nuke the build folder and start new.

[The most recent future]

@SGaist
yes ， make clean && make distclean
when i change the configure ， i will be make clean and make distclean,
but, the error will be show .

[SGaist]

What does the configuration summary show ?

[The most recent future]

@SGaist
1 : make and make install

               Looks like a success
               data size : 108 M
               but, why the example files  is not be generated ???
