c - Quartz的GTK窗口[从GStreamer的问题开始]

我正在尝试让GStreamer SDK的basic-tutorial-5在OSX上工作。

从http://gstreamer.freedesktop.org/data/pkg/osx/1.2.4.1/下载的SDK

http://cgit.freedesktop.org/~slomo/gst-sdk-tutorials/的教程(针对1.0)

我收到以下错误

basic-tutorial-5.c:5:10: fatal error: 'gst/video/videooverlay.h' file not found

当我运行时

gcc `pkg-config gstreamer-1.0 gtk+-3.0 --cflags --libs` basic-tutorial-5.c -o basic5

任何指针都将有所帮助!

谢谢。

编辑:
gst/video/videooverlay.h中有一个/local/frameworks/Gstreamer.framework/Headers。
pkg-config gstreamer-1.0 gtk+-3.0 --cflags --libs的输出不包括/Library/Frameworks/Gstreamer.framework/Versions/1.0/Headers
感谢@Biffen在使用时

    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

所以它符合...这似乎是向前迈出的一大步，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:

多亏了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``编译并运行./basic5来获取以下错误:

Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded!

(basic5:77683): 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(以及其他无疑的文件夹)，因此使用pkg-config..可能是一种解决方法。

如果我在XQuartz终端中运行./basic5，则会出现以下错误:

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

其他人有什么想法吗？

最佳答案

对于最初的问题，解决方案取决于您的系统，因此很难给您一个好的答案，但是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，如果您使用的是GStreamer SDK，则根据GStreamer SDK文档you should be using -framework GStreamer而不是pkg-config。

至于您看到的关于“无法注册现有类型”的错误，当您尝试链接同一库的两个不同版本时，往往会发生这种错误。 TBH我从未见过gchar会发生这种情况，但这可能意味着您正在尝试链接到glib或gobject的两个不同版本，这很有意义-gtk+-3.0 pkg-config文件将把glib-2.0和gobject-2.0作为依赖项，它们都已经包含在GStreamer SDK中。 GStreamer SDK中还包含AFAICT GTK +，因此请尝试摆脱pkg-config的内容:

gcc -o basic5 basic-tutorial-5.c -I/Library/Frameworks/Gstreamer.framework/Versions/1.0/Headers -framework GStreamer
