since they always need a C compiler, even when the source code is
completely in C++.
For some other packages, stated in the comment that a C compiler is
really not needed.
GEOS (Geometry Engine - Open Source) is a C++ port of the Java
Topology Suite (JTS). It contain the complete functionality of JTS in
C++. It includes all the OpenGIS "Simple Features for SQL" spatial
predicate functions and spatial operators,and JTS topology functions
like IsValid().
