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"
|
||
|
|
----
|
||
|
|
|
||
|
|
That script has access to the following variables:
|
||
|
|
|
||
|
|
- +BUILDROOT_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
