Hello!  
I would like to create an SDK for R17, which should be generated by the `make toolchain_bin` command. My problem is that after adding json-glib to the image.inc and compiling the SDK, the SDK does not include the library, although it seems to have been successfully compiled under build\_bin/tmp/work/…/json-glib/. Does anyone have any ideas why it’s not getting included in the SDK?  
Thanks

I guess image.inc is for yocto image only, not for the toolchain

i don’t have any experience on building the toolchain, but here says you need to modify

> Hi Voloviq, Using another toolchain with the WP85 might not be so easy, as there is a lot of compatibility issues between libraries that are in the toolchain and on the target. In the end building the QT5 support within the WP85 Yocto distribution might actually be a simpler course of action. There is this article on how to use a meta-qt5 layer: [http://wiki.wandboard.org/index.php/Building\_Qt5\_using\_yocto\_on\_Wandboard](http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard) Yocto 1.7 is called dizzy so you would need to take [GitHub - meta-qt5/met…](https://github.com/meta-qt5/meta-qt5/tree/dizzy)

It also says " compiled binaries are located in ~/…/build\_bin/tmp/sysroots/x86\_64-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-", I wonder if you can manually add your own library there and pack as a .sh file

As far as I know, it should be sufficient to insert the nativesdk class into BBCLASSEXTEND; however, it seems that in this case, it doesn’t happen, unlike what I observe in the recipes.

I wonder if you can manually put required files in ~/…/build\_bin/tmp/sysroots/x86\_64-linux/usr/bin/arm-poky-linux-gnueabi/

And then make the toolchain
