Question

我正在尝试使用wirePiPi库通过clion IDE运行c程序。 Hello world运行良好，因此我可以确保与pi的连接已正确建立。但是，当我添加connectioningPi-Library #include并运行connectionPictureSetup（）时；我收到一条错误消息。

为了解决此问题，我在Clion / Preferences / Build，Execution，Deployment / CMake / Build选项中添加了“ -lwiringPi”。但是，这没有任何改变。也许在CMakeLists.c中缺少一些东西，但我实际上不知道什么。

#include <stdio.h>
#include <wiringPi.h>

// Code I want to make running
int main() {
    wiringPiSetup();
    return 0;
}

错误消息：

带有-lwiringPi的错误消息：
