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,

opencv_1.0.0.bb seems pretty out of date?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,

You can not just copy a recipe - if it has dependencies, then you need to copy those recipes too.

OR - the simpler thing to do

Add the entire meta layer to bblayers.conf

This is where the recipe says that it depends on "swig" and you likely do not have swig in any of your meta layers. Chances are - you can get swig from the same place you got the recipe for opencv
