飞碟和杂波-我怎么设置它？

Question

我已经使用了一段时间，但我不知道如何使它正确地识别克拉特。根据我发现的一个教程，我在Emacs中输入了这个(非常简单)程序：

#include <stdlib.h>
#include <clutter/clutter.h>

//draws a basic, black window
int main(int argc, char *argv[])
{
  ClutterInitError e = clutter_init(&argc, &argv); //pass it any
                                               //options - these
                                               //can be fed
  if (e == CLUTTER_INIT_SUCCESS) {
    ClutterColor stage_color = {0, 0, 0, 255}; //RGBA [0, 255]
    ClutterActor *stage = clutter_stage_new();
    clutter_actor_set_size(stage, 512, 512);
    clutter_actor_set_background_color(stage, &stage_color);
    clutter_actor_show(stage);
    clutter_main();
    return EXIT_SUCCESS;
  } else {
    return 1;
  }
}

现在，在第2行( #include <clutter/clutter.h>)中，我收到了Flycheck关于无法找到clutter/clutter.h的警告。很公平--在编译器中，我需要使用pkg-config成功地编译它。在我的系统中，pkg-config clutter-1.0 --cflags --libs输出：

-pthread -I/usr/include/clutter-1.0 -I/usr/include/pango-1.0 -I/usr/include/cogl -I/usr/include/cairo -I/usr/include/atk-1.0 -I/usr/include/pango-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/harfbuzz -I/usr/include/libpng16 -I/usr/include/cogl -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng16 -I/usr/include/libdrm -I/usr/include/json-glib-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -lclutter-1.0 -lcogl-path -lcairo-gobject -latk-1.0 -lpangocairo-1.0 -lpango-1.0 -lcairo -lcogl-pango -lcogl -lgmodule-2.0 -pthread -lgdk_pixbuf-2.0 -lwayland-egl -lgbm -ldrm -lEGL -lXrandr -ljson-glib-1.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0 -lwayland-cursor -lwayland-client -lxkbcommon -lwayland-server -lX11 -lXext -lXdamage -lXfixes -lXcomposite -lXi

现在，我有点像个C(也有点像一个Flycheck noob)，所以请原谅我。我知道我需要使用M-x customize-group flycheck-options，在那里，我需要在Flycheck GCC Include Path和Flycheck GCC Includes中添加一些东西。但是，我不知道上面输出的哪些部分(如果有的话)到哪里去了？我真的很想得到一些帮助，所以当我和其他库一起工作时，我会知道如何正确地设置它们。

在-I输出中以pkg-config clutter-1.0 --cflags --libs为前缀的所有路径都包括路径。

具体地说：

/usr/include/clutter-1.0
/usr/include/pango-1.0
/usr/include/cogl
/usr/include/cairo
/usr/include/atk-1.0
/usr/include/pango-1.0
/usr/include/cairo
/usr/include/pixman-1
/usr/include/freetype2
/usr/include/libpng16
/usr/include/harfbuzz
/usr/include/freetype2
/usr/include/harfbuzz
/usr/include/libpng16
/usr/include/cogl
/usr/include/gdk-pixbuf-2.0
/usr/include/libpng16
/usr/include/libdrm
/usr/include/json-glib-1.0
/usr/include/glib-2.0
/usr/lib/glib-2.0/include

将这些添加到Flycheck GCC Include Path中。
