Salil,
Hugen was able to compile the firmware for his prototype NanoVNA-V2 (same as Gabriel's project but with case and battery) so the complete source must be available somewhere. Gabriel is a member of this group and may be able to assist you.

I can compile firmware under Windows, use eclipse
Sources:
MCULIB
https://github.com/gabriel-tenma-white/mculib
libopencm3 version for gd32f3
https://github.com/nanovna/libopencm3-gd32f3
NanoVNA V2
https://github.com/nanovna/NanoVNA-V2-firmware

Under windows need install python, and fix
>libopencm3\mk\genlink-config.mk
>libopencm3\mk\genlink-rules.mk
All shell commands
>shell $(OPENCM3_DIR)
Change on
>shell python $(OPENCM3_DIR)

Also in NanoVNA-V2-firmware need set correct path MCULIB and libopencm3
>MCULIB ?= persist/mculib
>OPENCM3_DIR ?= persist/libopencm3

Before compile NanoVNA V2 need build libopencm3

I got it compiling on Debian.
Indeed change the Makefile to point to other two repos and build those first.
I used the arm none eabi compiler from the Debian repository.

Thanks for the git link to the MCULIB. I will clone the repo and try to do a first compile this weekend.
