if anyone could help that would be greatly appreciated thank you

It looks like you forgot to tell the linker about certain libraries your source code depends on.

You have a nice 3rd party library called 'FooBar'

In your source code, you say
#include <foobar.h>

To make it compile, you tell your compiler / IDE / Makefile some information on where to find the header file. From the command line, you would add -I/path/to/foobar/include which is the directory containing foobar.h

To make it link (ie, resolve all those undefined reference to errors), you also have to tell the linker the same kind of information. Say FooBar is compiled as a library called libfoobar.a which happens to be in /path/to/foobar/lib.
From the command line, you would add -L/path/to/foobar/lib -lfoobar to tell the linker the location and name of the library.
