OpenDMTP configuration on Linux machine - c++

Question

I've successfully installed and run the OpenGTS server application using the HTTP based GPRMC servlet.
Now I'm attempting to run the OpenDMTP C Client on linux. I get stuck at the very first step.
When I try to use the make command in the terminal:
make dest=linux dmtp
I get the following errors:
Linking 'dmtpd' ...

It appears math.h isn't being accessed by the file. I think the program doesn't include the headers from the \usr\include directory but don't know how to add this path to the makefile. Please help!
Please help!
