带有Quartz的GTK窗口
我正在尝试使用GStreamer SDK的basic-tutorial-5来处理OSX。
SDK从http://gstreamer.freedesktop.org/data/pkg/osx/1.2.4.1/下载
来自http://cgit.freedesktop.org/~slomo/gst-sdk-tutorials/的教程（适用于1.0）
我收到以下错误
basic-tutorial-5.c:5:10: fatal error: 'gst/video/videooverlay.h' file not found 我跑的时候
gcc `pkg-config gstreamer-1.0 gtk+-3.0 --cflags --libs` basic-tutorial-5.c -o basic5
任何指针都会有所帮助！
谢谢。
编辑：
gst/video/videooverlay.h中有一个gst/video/videooverlay.h /local/frameworks/Gstreamer.framework/Headers 。
pkg-config gstreamer-1.0 gtk+-3.0 --cflags --libs不包括/Library/Frameworks/Gstreamer.framework/Versions/1.0/Headers
感谢@Biffen使用时
gcc `pkg-config --cflags --libs gtk+-3.0` -o basic5 basic-tutorial-5.c -I/Library/Frameworks/Gstreamer.framework/Versions/1.0/Headers -framework GStreamer
还有一点动作：

所以它符合……这似乎向前迈出了一大步，但仍然没有雪茄……
当我尝试运行basic5时，我得到：
(process:73178): GLib-GObject-WARNING **: cannot register existing type 'gchar' ** GLib-GObject:ERROR:gvaluetypes.c:455:_g_value_types_init: assertion failed: (type == G_TYPE_CHAR) Abort trap: 6
编辑v2：
感谢nemequ我现在可以使用gcc -o basic5 basic-tutorial-5.c pkg-config –libs –cflags gstreamer-1.0 gstreamer-video-1.0 gtk + -3.0“进行编译并运行./basic5以获取以下内容错误：
Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded! (basic5:77683): Gtk-WARNING **: cannot open display:
似乎/Library/Frameworks/Gstreamer.framework/Versions/1.0/Headers文件夹中缺少gtk文件夹（以及其他文件，毫无疑问），所以使用pkg-config..是一种解决方法。
如果我在XQuartz终端中运行./basic5 ，我会收到以下错误：
Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded! (basic5:78227): GLib-GIO-ERROR **: No GSettings schemas are installed on the system Trace/BPT trap: 5
别人有什么想法吗？
对于最初的问题，解决方案取决于您的系统，因此给您一个很好的答案有点困难，但gst / video / videooverlay.h是gstreamer-video-1.0软件包的一部分， 而不是 gstreamer-1.0 。
也就是说，如果您正在使用GStreamer SDK，那么根据GStreamer SDK文档， 您应该使用-framework GStreamer ，而不是pkg-config。
至于您所看到的“无法注册现有类型”的错误，当您尝试链接同一个库的两个不同版本时，往往会发生这种错误。 TBH我从来没有见过它与gchar一起发生，但它可能意味着你正在尝试链接到两个不同版本的glib或gobject，这是有道理的 – gtk+-3.0 pkg-config文件将gobject-2.0 glib-2.0和gobject-2.0作为依赖项，它们都已包含在GStreamer SDK中。 AFAICT GTK +也包含在GStreamer SDK中，所以试着摆脱pkg-config的东西：
gcc -o basic5 basic-tutorial-5.c -I/Library/Frameworks/Gstreamer.framework/Versions/1.0/Headers -framework GStreamer
