Welcome to sysroot cruft finding utility.

--tmpdir=<tmpdir>
|

|
|
Specify tmpdir, will use the environment variable TMPDIR if it is not specified.
|
||
|
|
Something like /OE/oe-core/tmp-eglibc (no / at the end).
|
||
|
|
|
||
|
|
--whitelist=<whitelist-file>
|
||
|
|
Text file, each line is regular expression for paths we want to ignore in resulting diff.
|
||
|
|
You can use diff file from the script output, if it contains only expected exceptions.
|
||
|
|
'#' is used as regexp delimiter, so you don't need to prefix forward slashes in paths.
|
||
|
|
^ and $ is automatically added, so provide only the middle part.
|
||
|
|
Lines starting with '#' are ignored as comments.
|
||
|
|
All paths are relative to "sysroots" directory.
|
||
|
|
Directories don't end with forward slash.
