--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).
|
||
|
|
|
||
|
|
--machines=<machines>
|
||
|
|
List of MACHINEs separated by space, will use the environment variable MACHINES if it is not specified.
|
||
|
|
Default value is "qemuarm qemux86 qemux86-64".
|
||
|
|
|
||
|
|
--targets=<targets>
|
||
|
|
List of targets separated by space, will use the environment variable TARGETS if it is not specified.
|
||
|
|
Default value is "core-image-base".
|
||
|
|
|
||
|
|
--analyze
|
||
|
|
Show the differences between MACHINEs. It assumes:
|
||
|
|
* First 2 MACHINEs in --machines parameter have the same TUNE_PKGARCH
|
||
|
|
* Third optional MACHINE has different TUNE_PKGARCH - only native and allarch recipes are compared).
|
||
|
|
* Next MACHINEs are ignored
