Run C ++ in eclipse and report launch failed. Binary not found Solution

After the configuration is complete, create a project test. You can run the test after setting up a project of the hello World C ++ project type. If you directly create an empty project and write a test class, the system prompts "launch failed. binary not found ", cause: after each new project in the CDT is built, the system generally performs the first build by default, that is, the executable file is automatically generated. However, the fact is that the newly created project does not even have source code
Of course, it will not generate executable files. When we create a new source code file, click the execute button to display the "launch failed. Binary not found" prompt description (the executable binary file cannot be found ).

Solution: Right-click the project folder on the left of the window, select build deployments ---> build --> select from the pop-up menu, and select debug or release to build.After the configuration is complete, create a project test.
