Custom Linux distro - mono runtime not found

Question

I am trying to add mono to core-image-minimal for P202RDB custom Linux distro. Here is my bblayers.conf file:

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
LCONF_VERSION = "6"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
  /home/testuser/QorIQ-SDK-V1.9-20151210-yocto/sources/poky/meta \

  "

Now, when I try to build image using bitbake core-image-minimal, I get following output from it:

It seems mono repository is found, then I prepare SD card using this image and it boots without problems on target board, however, mono command is not available. What am I missing?

Answer 1

Add

 IMAGE_INSTALL_append = " mono"

to your local.conf. Just adding a layer doesn't add any package to your image.

Even better, create your own image, and add mono to IMAGE_INSTALL in that recipe.
