Let
$ {\mathbb F}_q $
 be the finite field with
$ q = p^m $
 elements, where
$ p $
 is an odd prime and
$ m $
 is a positive integer. Let
$ \operatorname{Tr}_m $
 denote the trace function from
$ {\mathbb F}_q $
 onto
$ {\mathbb F}_p $
, and the defining set
$ D\subset {\mathbb F}_q^t $
, where
$ t $
 is a positive integer. In this paper, the set
$ D = \{(x_1, x_2, \cdots, x_t)\in {\mathbb F}_q^t:\operatorname{Tr}_m(x_1^2+x_2^2+\cdots+x_t^2) = 0, \operatorname{Tr}_m(x_1+x_2+\cdots+x_t) = 1\} $
. Define the
$ p $
-ary linear code
$ {\mathcal C}_D $
 by
$ \begin{eqnarray*} {\mathcal C}_D = \{\textbf{c}(a_1, a_2, \cdots, a_t): (a_1, a_2, \cdots, a_t)\in {\mathbb F}_q^t\}, \end{eqnarray*} $
where
$ \textbf{c}(a_1, a_2, \cdots, a_t) = (\operatorname{Tr}_m(a_1x_1+a_1x_2\cdots+a_tx_t))_{(x_1, \cdots, x_t)\in D}. $
We evaluate the complete weight enumerator of the linear codes
$ {\mathcal C}_D $
, and present its weight distributions. Some examples are given to illustrate the results.
Keywords: Linear code, complete weight enumerator, cyclotomic number, Gauss sum.
