fst folder is a library I added.

Problem

I can compile active file and intellisense is fine. But every time I click the Run Code button, it gives the following error:

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.

CodePudding user response：

Okay

First

Try use CMake extension

Second

Run Code does one simple thing - it compiles and runs the program from your current file.

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

Compilation at this point knows nothing about your CMake project, compilation flags, include paths, etc.

If you're trying to build your entire CMake project this way, it won't work. You need to build exactly the CMake project, and run exactly the compiled application (the easiest way to do this is with the extension from the first paragraph).
