Yocto - "bitbake projucer-native" gives pkg-config error?

Linux
1

Hi all,
I am trying to use yocto to build a linux distro for my raspberry pi 3 Juce project.
If I try to “bitbake projucer-native” I always get errors related to the pkg-config, as if some packages where missing.
If I try “pkg-config --list-all” it shows these packages (‘gtk±x11-3.0’ and 'webkit2gtk-4.0’ ) are there. (on my build machine, since it`s na native) I also compiled JUCE/Projucer successful before without yocto on my build machine using the installJUCE.sh script from the Forum.

Any ideas would be appreciated.
Thx, Clemens

It seems there is no ‘gtk±x11-3.0’ installed as well as 'webkit2gtk-4.0’
Maybe just try to install them again?

I had similar problem to get working the software under Yocto which uses this webkit2gtk-4.0. AFAIR the webkit was not neccessary in JUCE 4. I have no time to investigate it, so I just removed the modules from my software referring to the webkit package when compiling with JUCE 5.

Yes. I know it seems like this. But I successfully installed JUCE 5 with the install script (and it has the same dependencies, right?)
Also “pkg-config --list-all” gives me a list of all pkg-config-packages and ‘gtk±x11-3.0’ as well as 'webkit2gtk-4.0’ are in this list.

The Problem could be something with the pkg-config, since in yocto you seem to have 2 pkg configs (one for the target an one for the host). But I dont know how to handle those.

Has anybody successfully used yocto to build a Juce 5 image (which automatically bitbakes projucer-native, right?) ?

I’m not an expert with Yocto so this may be completely irrelevant to your problem:

JUCE’s WebComponent needs webkit2gtk-4.0 and gtk-x11-3.0, if your project is not using the WebComponent you can disable it which will remove the dependency. You can do this in two ways:

  1. Remove the juce_gui_extra module from your project. This will remove any other things that are also in the juce_gui_extra module.

  2. Or disable JUCE_WEB_BROWSER in the Projucer:
    31

However, the Projucer does use the WebComponent so you will need those dependencies on your build machine (not the target) so that you can build the Projucer.

Thanks, but I think the problem ist that as soon as you want to bitbake any juce-recipe (even without WebComponent), yocto tries to install the projucer on the build machine (thats what the “native” in “projucer-native” stands for.
So the problem seems to be with the build machine configuration.

So maybe:

  • pkg-config or pkg-config-wrapper is faulty : Since yocto needs 2 different pkg-config-configurations, one for target and one for build machine. But for the build machine only webkit2gtk-4.0 and gtk-x11-3.0 are missing so far, all others seem to work? I got gtk-x11-3.0.pc and webkit2gtk-4.0.pc file in /usr/lib/x86_64-linux-gnu/pkgconfig but the PKG_CONFIG_PATH- environment variable doesn’t seem to apply to the yocto - native/build machine pkg-config.

  • since for example gtk-x11-3.0 seems to be missing on the build machine to compile the projucer-native maybe I would need to add something like gtk+3-native to the recipe. But nothing provides this.

Sorry this is beyond me, but I believe that @ftonello wrote the original yocto recipes. Maybe you can send him a pm?

I will do that, thank you

I have replied to it here.
