我正在努力为BeagleBoard开发。

因此我安装了CodeSourcery SourceryG ++ Lite Toolchain。

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，我想用ARM架构的其他工具链编译相同的应用程序。

编译/链接时，我得到这些警告/错误：

collect2: ld returned 1 exit status显然，即时通讯使用相同的include-directories和library-pathes，如im用于x86架构。这不起作用。但我需要做什么？我必须交叉编译opencv库吗？
