We deal with compact linear mappings of a normed linear space, within the framework of Bishop's constructive mathematics. We prove the constructive substitutes for the classically well known theorems on compact linear mappings: T is compact if and only if \(T^*\) is compact; if S is bounded and if T is compact, then TS is compact; if S and T is compact, then \(S+T\) is compact.
