Make error while installing the client

[rohansuri1996]

Hi

I am using the guide provided to install all the 3 components. I am trying to install the client and I am getting an error which I am not able to fix.

Command:

make

Error:

collect2: error: ld returned 1 exit status
make[2]: *** [Makefile:484: fwknop] Error 1
make[2]: Leaving directory '/home/user/Desktop/SDPClient_Gateway/fwknop/client'
make[1]: *** [Makefile:907: all-recursive] Error 1
make[1]: Leaving directory '/home/user/Desktop/SDPClient_Gateway/fwknop'
make: *** [Makefile:839: all] Error 2

It would be great if you can give me insight how can I fix it. Thank you.
