gst交叉编译的问题

[gaoshanzhishui]

当我在mips交叉编译环境下编译好了gst-plugin插件之后，然后拷贝到相应的位置之后，用gst_plugin_load_file（）函数调用，但是当我执行的时候，用GST_DEBUG log出来的数据错误如下：
0:00:05.265398000 1607 0x4c8100 WARN GST_PLUGIN_LOADING gstplugin.c:769:gst_plugin_load_file: module_open failed: File not found

(rygel:1607): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.

这是为什么呢，一开始我怀疑是那些插件都是在gst-plugin的ext目录下得原因，但是我编译源码包ext目录下自带的插件就可以load，然后我又想是不是需要下载支持库的插件会出现这种问题，但是我下载libmad，然后编译mad的时候，也可以load成功。
我真是无语了，求大侠解答。
