chris larson's cool "bitbake-env" utility

[Robert P. J. Day]

  possibly prompted by my incessant whining, chris larson wrote a
nifty utility called "bitbake-env"; i wrote a quick page about it
here:

http://www.crashcourse.ca/wiki/index.php/OE_bitbake-env_utility

this is going to be more than a little useful in my courses.

Yeah - this looks great.

I put a link to your page on my bitbake cheat sheet page at:

  thanks.  i just started a somewhat different bitbake tutorial page
you can see buried in the midst of a bunch of other stuff here:

  http://www.crashcourse.ca/wiki/index.php/OE_Yocto_pages

i'm collecting links to all of my arbitrary, disorganized OE/yocto
wiki pages in one place, and you can see there's a section for bitbake
stuff, with one link going back to your cheat sheet.

  my (in-progress) bitbake tutorial will be a hands-on walkthrough of
the simpler features of bitbake, so new users can follow along, run
the commands and actually see what happens, so it's definitely not a
reference or cheat sheet in that sense of the word.

  adding more stuff to that "tutorial" page as we speak ...

  as someone who has never bothered to play with any of the UIs and is
thus asking from a position of total ignorance, i have a couple
questions about the "User interfaces" section of that cheat sheet.

  using stock oe-core, i followed your cheat sheet and tried this:

$ bitbake

and got:

ERROR: Timeout while attempting to communicate with bitbake server

so i need to start the server?  should that be mentioned there?

  i then tried:

$ bitbake -u knotty2
FATAL: Invalid user interface 'knotty2' specified.
Valid interfaces: depexp, goggle, ncurses, hob, knotty [default].
$

  just pointing out that if i follow that cheat sheet to the letter, i
run into problems.

what would you expect to get when launching bitbake without any
argument ?

  i was just pointing out the potential confusion in the cheat sheet
for people unfamiliar with the UIs, nothing more.

I was just pointing out the reason of the problem you saw and raised on
this mailing list, sorry for the inconvenience.

Hmmm.  With bitbake from poky-1.2-denzil I get:
"Nothing to do.  Use 'bitbake world' to build everything, or run 'bitbake --help' for usage information."

I think that "bitbake <nothing>" is not really a valid invocation.
I've changed the page accordingly.

It looks like knotty2 was an experimental interface, with features
now folded into knotty in poky-1.3-danny.

I removed it from the page.

Thanks very much for trying things out and reporting the problems.

I've altered the page to hopefully address the issues.

Maybe I should mention that I'm using the bitbake from the yocto project?
I didn't think they were diverged very far.

  never mind, just my incoherence ... when i was reading up on
"bitbake -u hob", i also read that "-u" had a default value of knotty,
so i assumed, oh, then i should be able to run just "bitbake" (even
though i had no idea what that would represent).  just silliness on my
part.
