[R] question about /nmath/standalone

I can't link a c code with Mathlib according to introduction of R
manual "Writing R Extensions", page 60.
It is written :
"It is possible to build Mathlib, the R set of mathematical functions
'Rmath.h, as a standalone library 'libRmath under Unix and Windows. (This
the functions documented in Section 5.7 [Numerical analysis subroutines], page
61 as fromthat header file.)
The library is not built automatically when R is installed, but can be built
directory 'src/nmath/standalone in the R sources: see the file 'README
there. To use thecode in your own C program include
and link against '-lRmath. There is an example file 'test.c."
Have I to do: gcc -lRmath test.c ? In this case I receive this message:
> /usr/bin/ld: cannot find -lRmath
> collect2: ld returned 1 exit status "
what should I do? or I do something before I use "gcc -lRmath test.c" to
compile c code test.c?
I will appreciate if you can help me resolve this problem.
