I want to develop an ALSA application on my i.MX6 sabre development board, but it looks like no headers (i. e. <alsa/asoundlib.h>) for ALSA aren´t installed in the imx-image-full image. I´ve checked the packages in the recipe and ALSA is included. I do not understand why the headers aren´t included.
alsa-lib
alsa-plugins
alsa-state
alsa-tools
alsa-topology-conf
alsa-ucm-conf
alsa-utils
imx-alsa-plugins
I´ve read that I need alsa-dev added to the recipe. Is this correct? And how can I add these headers to my image?
alsa-lib Rprovides alsa-dev
You just need to add alsa-dev to IMAGE_INSTALL:
IMAGE_INSTALL:append = " alsa-dev"
Before flashing your image, check your rootfs:
bitbake -e <your_image_name> | grep ^WORKDIR=
And do:
ls <workdir_path_from_previous_command>/rootfs/usr/include/asoundlib.h
