Based on the Guo-Krasnoselskii's fixed-point theorem, the existence and
multiplicity of positive solutions to a boundary value problem (BVP) with two
integral boundary conditions
are obtained, where $f$, $g_1$, $g_2$ are all continuous. It generalizes the results
of one positive solution to multiplicity and improves some results for integral
BVPs. Moreover, some examples are also included to demonstrate our results
as applications.
