PACKAGECONFIG ?

PACKAGECONFIG ?

[JC]

Hi,

I'm sorry about that, but it's impossible to find the information anywhere:

In many bb files you find some "PACKAGECONFIG" variables which are 
configure options, such as the following examples:


meta-multimedia/recipes-multimedia/sox/sox_14.4.0.bb:PACKAGECONFIG ??= 
"${@base_contains('DISTRO_FEATURES', 'pulseaudio', 'pulseaudio', '', d)} \
meta-multimedia/recipes-multimedia/sox/sox_14.4.0.bb:PACKAGECONFIG[pulseaudio] 
= "--with-pulseaudio=dyn,--with-pulseaudio=no,pulseaudio,"
meta-multimedia/recipes-multimedia/sox/sox_14.4.0.bb:PACKAGECONFIG[alsa] 
= "--with-alsa=dyn,--with-alsa=no,alsa-lib,"
meta-multimedia/recipes-multimedia/sox/sox_14.4.0.bb:PACKAGECONFIG[wavpack] 
= "--with-wavpack=dyn,--with-wavpack=no,wavpack,"

How can I tell bitbake to use / not use such options? for instance if I 
want to build sox with wavpack and without pulseaudio ?
There's probably something I should add somewhere in my local.conf, but 
I can't figure out what.

Thanks !

Regards
Jay

I usually like to think that I'm not here to be expert, but to rise
experts. So, please, keep
questions coming.

What you would do in local.conf is:

PACKAGECONFIG_pn-sox = "alsa"
PACKAGECONFIG_pn-sox += "wavpack"

in case you want to add alsa AND wavpack (I really have no idea if
this selection makes sense together)


But, from sox_14.4.0.bb file you can see:


PACKAGECONFIG ??= "${@base_contains('DISTRO_FEATURES', 'pulseaudio',
'pulseaudio', '', d)} \
                   ${@base_contains('DISTRO_FEATURES', 'alsa', 'alsa', '', d)} \
                   magic \
"

So, PACKAGECONFIG will be automatica filled (if you don't on
local.conf) based on DISTRO_FEATURES.

At least for pulseaudio, and alsa support.

So, I think it makes sense to you avoid pulseaudio, remove it from
DISTRO_FEATURES. But it will affect your whole system.

Thanks :)

Great!!!

For information, I also figured that in my own layer I can use bbappend 
and tell:

PACKAGECONFIG +="alsa wavpack"

But that's a different need. Yours also make sense :)

BTW, that was an example, I do not intend to do this, that was just a 
package to enlight my question :)

Thanks !!!
