To include strace in your system, add the following to your conf/local.conf file:

IMAGE_INSTALL_append = " strace" 

Strace is also part of the tools-debug image feature, so you can also add it with:

EXTRA_IMAGE_FEATURES += "tools-debug" 

Strace is also included in the -sdk images.

Before starting, we will also include pgrep, a process utility that will make our debugging easier by looking up process IDs by name. To do so, add the following to your conf/local.conf configuration file:

IMAGE_INSTALL_append = " procps"
