The path searched depends on the implementation (and current configuration). The correct way to find the include path is to use pkg-config
搜索的路径取决于实现（和当前配置）。找到包含路径的正确方法是使用pkg-config
pkg-config --cflags gstreamer

The default path for <>stuff is /usr/include, at least on Unix.
至少在 Unix 上，<>东西的默认路径是/usr/include。
You can add as many default paths as you want with -I /my/new/pathcompiler option.
您可以使用-I /my/new/path编译器选项添加任意数量的默认路径。

Try running gcc -v -E -. When I do, part of the output is as follows:
尝试运行gcc -v -E -。当我这样做时，部分输出如下：
#include <...> search starts here:
/usr/lib/gcc/i686-linux-gnu/4.6.1/include
/usr/local/include
/usr/lib/gcc/i686-linux-gnu/4.6.1/include-fixed
/usr/include/i386-linux-gnu
/usr/include
It's not an answer to the gstreamer question, but I hope this still helps!
这不是 gstreamer 问题的答案，但我希望这仍然有帮助！

The default paths are
默认路径是
/usr/local/include
/usr/include
If you use another path, you can add in your compile command with -Iflag. In your case, assuming you have a /usr/local/gst/includedirectory, you may add -I/usr/local/gst/includeand use #include <whatever_you_need.h>
如果使用其他路径，则可以在编译命令中添加-I标志。在你的情况下，假设你有一个/usr/local/gst/include目录，你可以添加-I/usr/local/gst/include和使用#include <whatever_you_need.h>
