I tried that and bitbake still fails when disabling the network

Hi Mohammad,

If it's failing during parsing that means you still have a recipe that does 
not have a proper SRCREV set, which you need to fix as described by the page 
that Alex linked. The error will be reporting which recipe that is.

Cheers,
Paul

Re: can bitbake build offline ?

Well, actually I used the find command in that wiki page to find the 
recipe that uses tag name to chose github revision and it found only one 
recipe

 >meta-openembedded/meta-initramfs/recipes-devtools/mtd/ubi-utils-klibc_1.5.1.bb

I masked this recipe in the local.conf file and bitbake failed at 
parsing other recipes, looking at those recipes I saw that they don't 
use tag names but they use

 >SRCREV = "${AUTOREV}"

which is logical since bitbake has to issue ls-remote to know what is 
the latest revision on the remote git repo (maybe the wiki page needs 
update to point this ?)

Now I can't remove this AUTOREV in these recipes since I need bitbake to 
fetch the latest updates ( I push updates regularly on that repo and I 
don't want to update the recipe file each time to add the latest revision)

So, here comes the hard part, Is it possible to tell bitbake to issue 
ls-remote if there is network and to use the latest fetched revision in 
the sources directory if the network is disabled ? that way I can use 
${AUTOREV} in my recipes and bitbake will build from the local repo in 
the sources directory unless there is network to update the local repo, 
probably there is no such thing :) .

Thanks

Hmm, right, it seems like you're using a previous branch - this got fixed
in a later update of that recipe.

So there isn't a mechanism to do exactly that, no, however you can sort of
achieve the same thing if you set up a .inc file that sets the SRCREV values
for each recipe and sets BB_NO_NETWORK at the same time (though the
latter could still be separate). e.g. let's call it no_network.inc:

BB_NO_NETWORK = "1"
SRCREV_pn-abc = "b4c2bd84ee6f699e348d602a82d2d0963384cdea"
SRCREV_pn-xyz = "e3b30def2cd1c9ede7630489c3949a45b6eba6ee"
..

Then to build offline you would just add the following to your config:

require no_network.inc

FYI you can enable buildhistory and use the buildhistory-collect-srcrevs 
script to generate all those SRCREV lines so you don't have to do that
by hand:

Re: can bitbake build offline ?

Wow that's a cool trick and it worked for me so ,thank you.

Also after some digging I found a solution that does exactly what I 
described in my previous message(I think), and I'm gonna leave it here 
in case someone face the same issue and find this message:

You can use set BB_SRCREV_POLICY = "cache" the local.conf which will 
prevent the AUTOREV recipes from failing by using the local cache for 
revisions

https://www.yoctoproject.org/docs/2.1/bitbake-user-manual/bitbake-user-manual.html#var-BB_SRCREV_POLICY

But If there is a new commits on the remote repo you probably need to 
disable this and rebuild to let bitbake fetch the latest revision and 
you can re enable it afterwards.


Regards

can bitbake build offline ?

[MOHAMMAD RASIM]

Hi, is there a way I can run a bitbake build offline? I have all the 
required sources of the target in the sources directory, and I have 
built the target multiple times with internet connection, but when I 
build offline it fails because it needs internet access during parsing 
recipes.
Can I tell bitbake to skip running `git ls-remote` during parsing 
recipes so I can build offline?

Thanks
