[yocto] yocto layer dependencies

[chandrasekhar chandrasekhar]

Hi ,   Some recipes produce many more packages. You can see what packages a given recipe produces using BitBake’s -e (show environment) command line switch   bitbake -e package_name | grep ^PACKAGES=        In your case if you want to know what packages available for petalinux just give bitbake -e petalinux | grep ^PACKAGES=Regards,ChandraFrom: ktreddy 70 <ktreddy70 at gmail.com>Sent: Sun, 3 Sep 2017 04:07:13 GMT+0530To: Fabian Knapp <knapp at ambibox.de>Cc: "yocto at yoctoproject.org" <yocto at yoctoproject.org>Subject: Re: [yocto] yocto layer dependencies Hi,Thank you,  issue got resolved after updating build/conf/bblayers.conf file,
Sorry to trouble you but now I am getting the following error what could be the reason

Do you have configured /meta-openembedded/meta-qt4/ in your bblayers.conf (build/conf/bblayers.conf)?

I am trying to set up yocto build environment for openlte, meta-sdr has most of the openlte depends
I am getting following error when I try to build sdr, 
 
 
/build$ bitbake sdr
Loading cache: 100% |############################################################################################################################################| Time: 0:00:00
Loaded 1642 entries from dependency cache.
ERROR: ParseError at /home/ktreddy/zcu102/sources/poky/../meta-openembedded/meta-sdr/recipes-applications/gqrx/gqrx_git.bb:8: Could not inherit file classes/qt4x11.bbclass
 
 
I do have meta-qt4 under meta-openembedded layer  as below.
 
zcu102/sources$ ls meta-openembedded/meta-qt4/classes/
qmake2.bbclass  qmake_base.bbclass  qt4e.bbclass  qt4x11.bbclass
 
 
could you please help me on why am I getting this error ?
How can I make one layer visible to another layer ?
Ex:  How can I make meta-sdr visible to openlte ? I mean how can I say to openlte that the dependency recipes are available under meta-sdr ?
 
if new recipes are available for a layer how can I get those on to my build environment ?
 
Thanks for your help.--_______________________________________________yocto mailing listyocto at yoctoproject.orghttps://lists.yoctoproject.org/listinfo/yocto
