ARM 9处理器的opencv交叉编译
我需要为 ARM 9 处理器交叉编译 opencv。我有处理器的工具链，但不知道如何交叉编译。请告诉我为arm板交叉编译的过程。
提前谢谢大家
i need to cross compile opencv for ARM 9 processor. I have the tool chain for the processor but don't know how to cross compile. Can some on please tell me the procedure of cross compiling it for the arm board.
Thank you all in advance

请参阅参考，了解交叉编译的说明。如果要编译的源代码支持 GNU 构建系统，则只需键入
./configure --host=arm-none-linux-gnueabi而不是./configure即可轻松完成>，但是所有类型的问题都可能发生（例如，构建系统尝试在构建过程中运行已编译的代码，这是不可能的，因为您是在 X86（我假设）机器上构建 ARM 代码）。也就是说，我在 OpenEmbedded 中查看了 opencv 的配方，并且它有大量的依赖项（您需要首先构建的东西）；例如 python、swig、glib (1)。所以我想说，您还有一些工作要做;)
(1) ：这些依赖项是 OpenEmbedded 给出的依赖项，您可能可以使用比指定的少的依赖项。
Look at this reference for a explanation of cross compiling. If the source to be compiled supports the GNU build system it should be as easy as typing
./configure --host=arm-none-linux-gnueabiinstead of./configure, but all types of problems can occur (e.g. that the build system tries to run compiled code during the build process which is not possible since you are building ARM code on a X86 (I assume) machine).That said I looked at the recipe for opencv in OpenEmbedded and it has an impressive number of dependencies (stuff you need to build first); e.g. python, swig, glib (1). So I would say that you have some work ahead of you;)
(1) : These dependencies are those given by OpenEmbedded and you might be able to get away with fewer than those specified.
我按照以下说明进行操作，并能够在 Ubuntu 工作站上交叉编译 OpenCV 2.4.2。我的目标是 ARM A8，但我相信它应该是相似的，即使不是完全相同的过程。

I followed the below instructions and was able to cross-compile OpenCV 2.4.2 on Ubuntu workstation. I am targeting ARM A8, but I beleive it should be similar if not exactly the same procedure.
