== Debugging Buildroot
It is possible to instrument the steps +Buildroot+ does when building
packages. Define the variable +BR2_INSTRUMENTATION_SCRIPTS+ to contain
the path of one or more scripts (or other executables), in a
space-separated list, you want called before and after each step. The
scripts are called in sequence, with three parameters:
- +start+ or +end+ to denote the start (resp. the end) of a step;
- the name of the step about to be started, or which just ended;
- the name of the package.
For example :
----
make BR2_INSTRUMENTATION_SCRIPTS="/path/to/my/script1 /path/to/my/script2"
----
The list of steps is:
- +extract+
- +patch+
- +configure+
- +build+
- +install-host+, when a host-package is installed in +$(HOST_DIR)+
- +install-target+, when a target-package is installed in +$(TARGET_DIR)+
- +install-staging+, when a target-package is installed in +$(STAGING_DIR)+
- +install-image+, when a target-package installs files in +$(BINARIES_DIR)+
The script has access to the following variables:
- +BR2_CONFIG+: the path to the Buildroot .config file
- +HOST_DIR+, +STAGING_DIR+, +TARGET_DIR+: see
xref:generic-package-reference[]
- +BUILD_DIR+: the directory where packages are extracted and built
- +BINARIES_DIR+: the place where all binary files (aka images) are
stored
- +BASE_DIR+: the base output directory
