8 It is possible to instrument the steps +Buildroot+ does when building
9 packages. Define the variable +BR2_INSTRUMENTATION_SCRIPTS+ to contain
10 the path of one or more scripts (or other executables), in a
11 space-separated list, you want called before and after each step. The
12 scripts are called in sequence, with three parameters:
14 - +start+ or +end+ to denote the start (resp. the end) of a step;
15 - the name of the step about to be started, or which just ended.
16 - the name of the package
21 make BR2_INSTRUMENTATION_SCRIPTS="/path/to/my/script1 /path/to/my/script2"
24 That script has access to the following variables:
26 - +BR2_CONFIG+: the path to the Buildroot .config file
27 - +HOST_DIR+, +STAGING_DIR+, +TARGET_DIR+: see
28 xref:generic-package-reference[]
29 - +BUILD_DIR+: the directory where packages are extracted and built
30 - +BINARIES_DIR+: the place where all binary files (aka images) are
32 - +BASE_DIR+: the base output directory
