-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Peter,
during this initial fetch it is true, that the repo fetcher has to download the repo sources from googlesource.com. But during this first fetch the fetcher also needs to download any sources listed in the repo manifest anyway, so internet access is a given. Consequential fetches will only re-run repo if: a) the SRC_URI or SRCREV has changed within the recipe b) the SRCREV is set to AUTOREV Both cases do not apply when reproducing a build offline. So if you have done this initial fetch of your sources and stash your working dir away, you can do an offline build. - -- With best regards Jasper Orschulko DevOps Engineer Tel. +49 30 58 58 14 265 Fax +49 30 58 58 14 999 [email protected] • • • • • • • • • • • • • • • • • • • • • • • • • • iris-GmbH infrared & intelligent sensors Schnellerstraße 1-5 | 12439 Berlin https://iris-sensing.com/ On Thu, 2021-11-11 at 14:11 +0000, Peter Kjellerstedt wrote: > > -----Original Message----- > > From: Jasper Orschulko <[email protected]> > > Sent: den 11 november 2021 13:10 > > To: [email protected]; openembedded- > > [email protected]; [email protected]; Peter > > Kjellerstedt > > <[email protected]>; [email protected] > > Cc: [email protected]; Daniel Baumgart > > <[email protected]>; > > [email protected] > > Subject: Re: [bitbake-devel] [oe-core][PATCH 1/2] devtools: Initial > > recipe > > for repo 2.17.3 > > > > -----BEGIN PGP SIGNED MESSAGE----- > > Hash: SHA256 > > > > Hi Peter, > > > > > However, this means > > > that only the source for the repo wrapper is available in DL_DIR. > > > So > > > when the repo wrapper executes it will try to go on the Internet > > > to > > > fetch the rest of the repo source, which will fail. > > > > just to clearify: Are we talking about installing repo on a target, > > or > > are we talking about the repo fetcher? > > The repo fetcher, i.e., when repo is used by bitbake. > > > When installing repo on the target, we do not call any "repo" > > command > > within the bitbake build process.
