2. Pay attention to these two settings when creating a Qt4 project:
Qt's location:/usr
"Debug/Release" options Output dir.: And Objects output dir.: Set to null, that is, the project root directory.

3. When you need to use the Q_OBJECT macro, an error is reported when you Build the macro directly. We need to use Qmake:
Click [Tools]-> [Configure tools...] to add two new Tools:
1)
Name: Create Qt Project File
Executable:/usr/share/qt4/bin/qmake <-- the absolute path of qmake on the local machine
Parameters:-project
Working directory: $ {PROJECT_DIR}
Launching options select Launch tool hidden with standard output redirected
Note: The command line window will not pop up.
Click OK.

2)
Name: Create Qt Makefile
Executable:/usr/share/qt4/bin/qmake <-- the absolute path of qmake on the local machine
Parameters:-makefile
Working directory: $ {PROJECT_DIR}
Launching options select Launch tool hidden with standard output redirected
Note: The command line window will not pop up.
Click OK.

4. Click [Project]-> [Properties...]-> [Project settings],
Check "This is a custom Makefile" to use the custom Makefile.

5. Click the "Build targets" option page above,
Change the "Type:" drop-down list box to "GUI application ".

6. Click [Project]-> [Build options...]-> "Make" commands option page to delete all $ targets.

After the preceding settings are complete, use the Create Qt Project File and Create Qt Makefile tools before compilation,
You can build it again.
