带有 Quartz 的 GTK 窗口 [从 GStreamer 的问题开始]

Question

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

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

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

我收到以下错误

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

当我跑

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：

有一个gst/video/videooverlay.h在/local/frameworks/Gstreamer.framework/Headers。

的输出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：

多亏了 nemequ，我现在可以使用gcc -o basic5 basic-tutorial-5.cpkg-config --libs --cflags gstreamer-1.0 gstreamer-video-1.0 gtk+-3.0`` 进行编译并运行./basic5得到以下错误：

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

(basic5:77683): Gtk-WARNING **: cannot open display:

似乎文件夹中缺少 gtk 文件夹（以及其他文件夹，毫无疑问） /Library/Frameworks/Gstreamer.framework/Versions/1.0/Headers，因此使用它可能pkg-config..是一种解决方法。

如果我./basic5在 XQuartz 终端中运行，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？

Answer 1

对于最初的问题，解决方案取决于您的系统，因此给您一个好的答案有点困难，但 gst/video/videooverlay.h 是包的一部分gstreamer-video-1.0，而不是 gstreamer-1.0.

\n\n

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 。

\n\n

至于您看到的有关“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，往往会发生这种情况。说实话，我从未见过 gchar 发生这种情况，但这可能意味着您正在尝试链接到两个不同版本的 glib 或 gobject，这是有道理的\xe2\x80\x94pkg- gtk+-3.0config 文件将拉入glib-2.0并gobject-2.0作为依赖项，并且它们都已包含在 GStreamer SDK 中。AFAICT GTK+ 也包含在 GStreamer SDK 中，因此请尝试删除 pkg-config 内容：

\n\n

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