Cross-compile

[Jongsik-mo]

Is it possible to cross-compile for the ARM processor ?
If so, please give me some advice.

I have built with yocto(bitbake).
And i am faced with the difficult errors as below.
Please help me..

you can build it from source, like every other software

Hi,

I was able to compile for mips using Open Embedded (I guess it will work for arm as well).

Here is the bitbake.

PS. I wasn't able to use sink-test yet, but that is not related with compiling thing.

Hi @athoik

Did you get to work with sink-test? I can build wds for arm using your recipe, but my Android can't find device to connect.

When I run sink-test I get:

# sink-test
* Registering Wifi Display with IE 00000600111C440032  

but I can't find any device from Android.

If I run scan p2p in connmanctl, connman finds my Androind device.

Hi @fbertux

I had a crash when using sink-test and never had time make further tests/debug.

So I shared my bitbake at least to make it usefull for others, that might have more time to play with.
