在Ubuntu上为Raspberry Pi交叉编译opencv项目

我现在正在为此挣扎2天，并没有得到它的工作。

到目前为止我所做的是：

• 在Ubuntu 12.04 LTS上从源代码构buildopencv 2.4.8 – > OpenCV项目编译并在ubuntu上运行

• 在Raspberry Pi上build立opencv 2.4.8来源Raspian – > OpenCV项目在Raspberry Pi上编译和运行

  • 在32位系统上安装64位glib2进行交叉编译
  • 在cygwin上的crosstool-ng构build中，gettext编译失败
  • 添加python-scipy到buildroot AM3352
  • mipsel-linux-gcc：找不到命令
  • “asm”错误中不可能的约束

• 用crosstools-ng为Raspberry Pi构build了一个交叉编译器（ http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi / ） – >在Ubuntu上构build的c ++程序，交叉编译器运行在Raspberry Pi上

我有什么问题：

|2|fatal error: opencv2/highgui/highgui.hpp: No such file or directory|

有了这个工具链，我试着用这个命令交叉编译OpenCV：

 cmake -DCMAKE_TOOLCHAIN_FILE=../Toolchain-RaspberryPi.cmake ../ 

在make命令之后，编译到27％。 有这个错误停止

所以我的问题是：

我怎样才能在Ubuntu上得到一个交叉编译器来使用opencv？ 我只想在Ubuntu上编译，在Pi上复制程序并在那里运行。

非常感谢
