Sdk does not containing json-glib

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 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?

I guess 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

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
