SRCREV variable

SRCREV variable

[Saxena, Rahul]

[-- Attachment #1: Type: text/plain, Size: 482 bytes --]

Hi ,

Can anyone explain how to set the SRCREV variable for a recipe ?

I get a error: "Please Set SRCREV to a valid value"

The poky manual simply has the following explanation:

'SRCREV               Revision of source code used to build package (Subversion, GIT, Bazaar only). '


For example if my source is MesaLib-7.9.tar.bz2 file from following site...what steps do I need to do to get the SRCREV ?

ftp://ftp.freedesktop.org/pub/mesa/7.9/



Thanks
Rahul

There is a bit more in the Yocto Project Reference Manual at http://www.yoctoproject.org/docs/latest/poky-ref-manual/poky-ref-manual.html.   It states:

SRCREV - The revision of the source code used to build the package.  This variable applies to Subversion, Git, Mercurial and Bazaar only.  Note that if you wish to build a fixed revision and you wish to avoid performing a query on the remote repository every time BitBake parses your recipe, you should specify a SRCREV that is a full revision identifier and not just a tag.

Also, Section 5.1.6 of that reference manual has some information on developing within Yocto Project for a package that uses an external SCM.

I am not sure if these will help you but this is where the latest documentation is for SRCREV.

Yes I saw this other stuff too...but I don't see anywhere the explanation of how a revision identifier is generated or obtained.

Thanks
Rahul

Rahul,

Okay - I was not sure whether it would help.  Hopefully one of the developers will chime in here and help.  My stuff was from the technical documentation point of view.

The value is entirely dependent upon the scm in use. git hash, svn
revision #, etc.

SRCREV is only used when you are fetching from some remote version control 
system (git, etc.). If it's complaining about it not being present then there 
must be some reference to a VCS in your SRC_URI. You can check this by running 
the following (replacing targetname as appropriate):

bitbake -e targetname | grep ^SRC_URI

Paul

Could you post some logs of the build showing this problem please?

Elsewhere you pointed out a recipe with a plain SRC_URI = "ftp://xxx"
address which would be the correct way to do this.

I suspect you have multiple mesa recipes and its selecting a "git://"
based one over the "ftp://" one you think its using. The "easy" way to
tell would be to delete the git mesa recipes and then it will probably
use the one you're expecting.

The better way to tell it to use the right recipe would be:

PREFERRED_VERSION_mesa = "7.9"

(assuming the recipe is called mesa)

It would be easier to help if we had some logs and more information
about what you're trying to do though, I'm just having to guess.

Cheers,

Richard
