Have had a lot of problems trying to get a recipe running.
I finally discovered that "COMPATIBLE_MACHINE" is sensitive to whitespace.
This is a real PITA expecially since COMPATIBLE_MACHINE is yet to be
documented in the manual
Indeed, it's a regular expression. This is mentioned in
documentation.conf:
COMPATIBLE_MACHINE[doc] = "A regular expression which matches the
MACHINES support by the package/file. Failure to match will cause the
file to be skipped by the parser."
If you think the description can be improved then I'm sure patches would
be welcome.
Its pretty clear, but this assumes that you are aware of the file itself.
Have just started looking into openembedded-core, so I didnt even know
the file existed.
Is this file mentioned anywhere?
I was looking at the openembedded "manual" in the home page
where COMPATIBLE_MACHINE is mentioned, but not much else.
Is there a reason to use a regular expression?
Why not a list of compatible machines?
Obviously you can have
COMPATIBLE_MACHINE = "at91*"
but if you need to list machines, and you have plenty of them
you have one very long line...
Working:
COMPATIBLE_MACHINE = "machine1"
COMPATIBLE_MACHINE = "machine1|machine2"
COMPATIBLE_MACHINE = "(machine1)"
COMPATIBLE_MACHINE = "(machine1|machine2)"
COMPATIBLE_MACHINE = "machine1"
COMPATIBLE_MACHINE += "|machine2"
I'm slightly surprised that this last example would work. It ought to
be equivalent to...
It seems to work for me.
I have in my U-Boot recipe:
COMPATIBLE_MACHINE =
"at91sam9260ek|at91sam9xeek|at91sam9g20ek|at91sam9g20ek_2mmc"
COMPATIBLE_MACHINE += "|at91sam9261ek|at91sam9g10ek"
COMPATIBLE_MACHINE += "|at91sam9263ek"
COMPATIBLE_MACHINE +=
"|at91sam9g45ek|at91sam9g45ekes|at91sam9m10ekes|at91sam9m10g45ek"
COMPATIBLE_MACHINE +=
"|at91sam9g15ek|at91sam9g25ek|at91sam9g35ek|at91sam9x25ek|at91sam9x35ek"
COMPATIBLE_MACHINE += "|at91sam9rlek"
MACHINE = "at91sam9g35ek"
If I add a space in the COMPATIBLE_MACHINE definition somewhere,
then the recipe is not used.
Hmm, I just realized why it will work.
If I try to build for "at91sam9263ek" then the regexp becomes
"at91sam963ek " (with a space),
so it will only work for machines which are not at the end of a line...
If I want to split into several lines, then I guess an ugly hack would be.
COMPATIBLE_MACHINE =
"at91sam9260ek|at91sam9xeek|at91sam9g20ek|at91sam9g20ek_2mmc|
XX1"
COMPATIBLE_MACHINE += "|at91sam9261ek|at91sam9g10ek|
XX2"
COMPATIBLE_MACHINE += "|at91sam9263ek|
XX3"
COMPATIBLE_MACHINE +=
"|at91sam9g45ek|at91sam9g45ekes|at91sam9m10ekes|at91sam9m10g45ek|
XX4"
COMPATIBLE_MACHINE +=
"|at91sam9g15ek|at91sam9g25ek|at91sam9g35ek|at91sam9x25ek|at91sam9x35ek|
XX5"
COMPATIBLE_MACHINE += "|at91sam9rlek"
