Question

我正在尝试在Netbeans上编译HAL API示例。 Netbeans显示有关某些头文件的警告和错误。但我可以使用以下命令行编译我的示例代码：

gcc `pkg-config --libs --cflags dbus-1 hal hal-storage dbus-glib-1 glib-2.0` main.c HalDemos.c HalDemos.h -o HalDemos -lpthread

如何将此命令应用于我的Netbeans项目？

这里是我要编译的代码：

更新

编写我与$$()一起使用的命令并将其添加到其他编译器设置解决了我的问题。

转到您的项目属性 - ＆gt;构建 - ＆gt; C编译器 - ＆gt;附加选项
将编译器标志放在$$()之间，如：

$$(pkg-config --libs --cflags dbus-1 hal hal-storage dbus-glib-1 glib-2.0)

如何在Netbeans上编译HAL示例？
