General Usage
GEOS is a C++ port of the Java Topology Suite (JTS). As such, it aims to contain the complete functionality of JTS in C++. This includes all the OpenGIS Simple Features for SQL spatial predicate functions and spatial operators, as well as specific JTS enhanced topology functions. It provides spatial functionality to many other projects and products.
In case you need to link against this library in your code, the following environmental variables have been defined:
- $GEOS_ROOT has been set to the root of the geos installation
- $GEOS_LIBDIR points to the directory containing the libraries
- $GEOS_INCDIR points to the directory containing the header files
You will probably wish to use these by adding the following flags to your compilation command (e.g. to CFLAGS in your Makefile):
- -I$GEOS_INCDIR
and the following flags to your link command (e.g. LDFLAGS in your Makefile):
- -L$GEOS_LIBDIR -Wl,-rpath,$GEOS_LIBDIR
