我正在努力爲BeagleBoard開發。 因此我安裝了CodeSourcery Sourcery_G ++ _ Lite工具鏈。linux交叉編譯和動態庫/鏈接
我想使用opencv庫。所以我將源碼下載到我的Ubuntu devolepment系統中，並使用gcc編譯爲共享庫並安裝了該庫。 當我爲x86架構構建helloworld應用程序時，一切都很好。
現在，我想編譯相同的應用程序與ARM架構的其他工具鏈。
我得到這些警告/錯誤回報在編譯/鏈接：
[email protected]:~/Downloads/BeagleTest$ arm-none-linux-gnueabi-g++ -c ImageProcessing.cpp -o ImageProcessing.o -I/usr/local/include

顯然，使用相同的IM包含的目錄使用的x86架構和庫pathes像IM。這不起作用。但我需要做什麼？我必須交叉編譯opencv庫嗎？
好的。非常感謝你。我會試一試。 – benlismo 2011-04-01 11:47:53
