Hi Ajay,
It seems you have to wait until Costin’s schedule lib to be merged.
[UNIKRAFT PATCH 13/17] lib/uksched: Updates for
inlining with plat/common changes
Or you can pick his patch series to your local repository for testing in advance.
Regards,
Wei Chen

Any pointers to any existing example usage of linking static-libraries would be useful.

But in the make-output, fdt_wip.c is being listed.

Hi All.
I am trying to integrate coremark-app in unikraft for x86_64.
It requires static linking to librt.a and libpthread.a; however seems they are not being picked up.
Following is the Makefile.uk :

I tried looking for any examples of linkage of OBJS files, but no example (for OBJS) is present in any of plat/app folder.
Kindly help me in fixing this.
