我正在努力为BeagleBoard开发。 因此我安装了CodeSourcery Sourcery_G ++ _ Lite工具链。linux交叉编译和动态库/链接
我想使用opencv库。所以我将源码下载到我的Ubuntu devolepment系统中，并使用gcc编译为共享库并安装了该库。 当我为x86架构构建helloworld应用程序时，一切都很好。
现在，我想编译相同的应用程序与ARM架构的其他工具链。
我得到这些警告/错误回报在编译/链接：
[email protected]:~/Downloads/BeagleTest$ arm-none-linux-gnueabi-g++ -c ImageProcessing.cpp -o ImageProcessing.o -I/usr/local/include

显然，使用相同的IM包含的目录使用的x86架构和库pathes像IM。这不起作用。但我需要做什么？我必须交叉编译opencv库吗？
好的。非常感谢你。我会试一试。 – benlismo 2011-04-01 11:47:53
