Edit: for reference, see here,

Ok, for others in the same situation, here's a proper way of doing it.

In your LEDE toolchain, call
./scripts/feeds update -a
./scripts/feeds install alsa-lib
./scripts/feeds install alsa-utils

run make again and your sysroot will be populated with alsa goodies.

As @Maximilian-Gerhardt mentioned, you need to actually install alsa on the Omega2 as well.

Sweet, thanks! This is allows me to continue.

If I find a way to add libasound to LEDE, I'll post something here. I believe this might be the right path, though seems a bit cumbersome.

Hi all,

noobish question perhaps, but how do I cross compile using libasound?

I have an app which now complains on a missing <sysroot>/include/alsa/asoundlib.h.

I'm compiling it with LEDE cross compiler according to this tutorial. In vain, I've done the menuconfig and enabled just about everything soundrelated under Kernel Modules/Sound Support and rebuilt the toolchain. I just can't seem to get libasound-dev into my sysroot

Or is there another way to install libs to LEDE sysroot?

Thanks a millions / Peter
