我正在嘗試在Ubuntu 12.04（32位）生成系統上爲ARM主機交叉編譯gstreamer。我將要描述的i686-linux-gnu GCC沒有任何描述。我在Ubuntu 12.04編譯使用該GCC：鏈接可執行文件時發現共享庫依賴關係

GCC從Ubuntu默認12.04的PPA安裝。當構建系統到達鏈接GST-發現者 - 1.0可執行文件，我得到以下錯誤：
/usr/lib/gcc/arm-linux-gnueabihf/4.6/../../../../arm-linux-gnueabihf/bin/ld: warning: liborc-0.4.so.0, needed by ../gst-libs/gst/video/.libs/libgstvideo-1.0.so, not found (try using -rpath or -rpath-link)

GST-發現者 - 1.0依賴於libgstvideo-1.0.so。 libgstvideo-1.0.so（在此過程中較早建立）對liborc-0.4.so具有依賴性。檢查與ARM-Linux的gnueabihf-readelf -a的libgstvideo-1.0.so得到下面的代碼片段：
Dynamic section at offset 0x29ed8 contains 33 entries:

home/test/gst/gstreamer/gstreamer/gst/.libs:/home/test/gst/gstreamer/orc/orc/.libs]
的路徑liborc-0.4.so在RPATH項正確。 gst-discoverer-1.0的鏈接行不包含對liborc的引用，因爲它不直接依賴於它（僅間接依賴於libgstvideo-1.0.so）。我曾嘗試在我的LDFLAGS中添加「-rpath-link =/home/test/gst/gstreamer/orc/orc/.libs」，但它不起作用。有關爲什麼交叉編譯鏈接程序無法找到此共享庫的依賴關係的任何想法？
