You mean how to compile a C program, linking both lapack and the 
standard C library to it? I suppose so in the following.

You probably need liblapack-dev also, which contains the header files 
needed to compile our program.

If it's a C program, you don't need the C++ standard library. Suppose 
your program is a file program.c. Try

gcc -llapack -lm -o program program.c

Usually you don't have to explicitly link the standard C library 
(because it is standard), except the math portions of it (so use the -lm 
switch if you are using math functions from the standard lib).
