Re: undefined reference error while build

Hi,

I understand the valid notions and concerns raised by you, but I as I was
trying to say in my last mail, that I were already doing these (suggested)
changes, but they were not reflected in my git diff file.
Reason being, I was 'unaware' of the fact that I am 'not' supposed to do
any changes in the solver folder, *while I did some there*, and those were
the changes one was unable to see in my git diff file. Knowing which I
corrected myself and got appropriate results.

Nevertheless, I am always happy to know and learn from my mistakes and have
been finally able to remove this error successfully :)

The most recent issue I am having is that, I 'make', the cpu reaches this
state and then does nothing (I left cpu for around 7 hours):
