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"
30 - +install-host+, when a host-package is installed in +$(HOST_DIR)+
31 - +install-target+, when a target-package is installed in +$(TARGET_DIR)+
32 - +install-staging+, when a target-package is installed in +$(STAGING_DIR)+
33 - +install-image+, when a target-package installs files in +$(BINARIES_DIR)+
35 The script has access to the following variables:
37 - +BR2_CONFIG+: the path to the Buildroot .config file
38 - +HOST_DIR+, +STAGING_DIR+, +TARGET_DIR+: see
39 xref:generic-package-reference[]
40 - +BUILD_DIR+: the directory where packages are extracted and built
41 - +BINARIES_DIR+: the place where all binary files (aka images) are
43 - +BASE_DIR+: the base output directory
