[yocto] to build the opencv lib

[Cui, Dexuan]

opencv_1.0.0.bb seems pretty out of date?

I think you can try opencv_2.3.bb of the meta-oe layer(this layer is well maintained):

https://github.com/openembedded/meta-oe/blob/master/meta-oe/recipes-support/opencv/opencv_2.3.bb
https://github.com/openembedded/meta-oe/blob/master/meta-oe/recipes-support/opencv/
https://github.com/openembedded/meta-oe

Good luck!

Thanks,

Subject: [yocto] to build the opencv lib

Hi,
   I want to build the opencv lib into yocto,but I have no idea to do it. I have copyed a opencv_1.0.0.bb file
into my layer,and after I do :bitbake opencv.,it comes the error:Nothing PROVIDES 'swig'(but ....)....
The recipe is the following,
