问题

我可以编译活动文件并且智能感知很好。但是每次我点击 Run Code 按钮时，都会出现以下错误：

cyan@machine:~/proj10$ cd "/home/cyan/proj10/" && g++ main.cc -o main && "/home/cyan/proj10/"main
main.cc:1:10: fatal error: A.h: No such file or directory
 #include <A.h>
          ^~~~~
compilation terminated.

好的

第一个

尝试使用 CMake extension

第二

Run Code 做一件简单的事情 - 它编译并运行从您当前的文件中提取程序。

cd "/home/cyan/proj10/" && g++ main.cc -o main && "/home/cyan/proj10/"main

此时的编译对您的 CMake 项目、编译标志、包含路径等一无所知。

如果您尝试以这种方式构建整个 CMake 项目，那将行不通。您需要准确地构建 CMake 项目，并且运行准确地构建已编译的应用程序（最简单的方法是使用第一段中的扩展）。
