1 个解决方案

You have 2 main() functions in the application that you are trying to compile. 您正在尝试编译的应用程序中有2个main()函数。

One is in task11.o and another one in main.o . 一个在task11.o ，另一个在main.o 。 Your application can have only one main function so remove one - not sure what exactly you are doing and which one is redundant. 您的应用程序只能有一个主要功能，因此请删除一个 - 不确定您正在做什么以及哪个是多余的。
