that means your link step is not linking libclang properly into your
app, perhaps change the order so -lclang appears last

Note performing 'nm' on libclang appear to show the majority present...

Question: if I needed to include a library, what/how would I modify a recipe under Yocto to be sure to include/link in the library ?

Thanks,

I am building meta-clang (sumo based 6.0.1), with cmake (3.8.2), all

Are the following routines accessible/supported under meta-clang ?

are you linking this library with libclang ? secondly, also check that its not emitting bunch of libraries which needs to then individually linked

thanks,
