wanting to clarify HOSTTOOLS and HOSTTOOLS_NONFATAL

wanting to clarify HOSTTOOLS and HOSTTOOLS_NONFATAL

[Robert P. J. Day]

  again, trying to catch up with new developments, and i want to make
sure i understand these variables. as i read it (and i could be
off-base), HOSTTOOLS represents a list of tools that *must* be
available one way or the other, and any tools listed there are allowed
to be symlinked from the tools available in PATH, is that correct?

  OTOH, HOSTTOOLS_NONFATAL represents whitelisted tools that will be
symlinked if they're there, but their absence is not fatal.

  i'm still not totally clear here ... and there is no mention of
these variables in the YP reference manual variables glossary.

  apologies for my confusion.

  oh, i think i asked this before as well ... how do these variables
relate to ASSUME_PROVIDED? IIRC, ASSUME_PROVIDED is interpreted as "i
have these utilities on my host, use them."

Correct. Perhaps you could send a patch to add these to the manual? :)

ASSUME_PROVIDED means that if something does DEPENDS += "x" and x is in
ASSUME_PRODIDED, bitbake won't try and build it or require a recipe for
it.

HOSTTOOLS is about filtering out tools from PATH for determinism.

Its unfortunate there is overlap between these but both are good things
to have in their own rights and I don't really see a way to automate it
in a 100% accurate way.

Cheers,

Richard
