C program using net-snmp does not compile

I have installed net-snmp 5.8 on a Ubuntu 16.0.4 machine and then I have checked the correct installation:

snmpget --version

NET-SNMP version: 5.8

Next, I am trying to write and compile my first SNMP C program example.

I have copied the one that is included as example on the tutorial from Ben Rockwood ("The Net-SNMP Programming Guide) and I have tried to compile it with the command:

gcc ‘net-snmp-config --cflags‘ ‘net-snmp-config --libs‘ \
> ‘net-snmp-config --external-libs‘ snmp_test.c -o snmp_test

As indicated in this tutorial.

When do, I get the errors:

gcc: error: unrecognized command line option ‘--cflags‘’ gcc: error: unrecognized command line option ‘--libs‘’ gcc: error: unrecognized command line option ‘--external-libs‘’

Then I have changed the gcc command to:

gcc net-snmp-config --cflagsnet-snmp-config --libs \

net-snmp-config --external-libs snmp_test.c -o snmp_test

And get the error:

bash: net-snmp-config --external-libs: ambiguous redirect

What is wrong on the gcc call? Any comments or suggestions are welcome.
