[Minios-devel] [Unikraft] Static Libraries not being linked properly

[Ajay Garg <ajaygargnsit@xxxxxxxxx>]

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 :

####################################################################
$(eval $(call addlib,appcoremark))

APPCOREMARK_SRCS-y              += $(APPCOREMARK_BASE)/core_main.c                                  \

                                                          -I$(APPCOREMARK_BASE)/../../unikraft/lib/nolibc/include/sys   \
                                                          -I/usr/include

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.

Thanks and Regards,

Ajay
