This is a small file. But I'm from the cocos2d-2.1rc0-x-2.1.3 under the official website. Then install the build-win32.bat. All went well. The third-party library files of each platform are missing in cocos2dx \ platform \ third_party. Cocosdenshion \ third_party is also a small library file. I don't know why I didn't extract it. But these library files are in the compressed files of the cocos2d-2.1rc0-x-2.1.3. No matter. If you extract the package and overwrite it, there will be no problem.
3. An error is reported when compiling the cccommon. cpp file.

This problem also occurs when Google goes to a foreign forum.
Because my ndk is R9, someone suggested to switch back to R8. I didn't try it. Finally, someone found this solution.
Modify the proj. Android \ JNI \ application. mk file of your project, and add
App_cppflags + =-wno-error = format-security.
