RSAGA (version 0.94-5)

rsaga.lib.prefix: Determine prefix for SAGA GIS library names

Description

Internal function that determines the possible prefix for SAGA GIS library names - relevant for non-Windows SAGA GIS pre-2.1.0.

Usage

rsaga.lib.prefix(env)

Arguments

env

list, setting up a SAGA geoprocessing environment as created by rsaga.env.

Value

A character string, either "" or "lib".

Details

Some non-Windows versions of saga_cmd require library names with a "lib" prefix, e.g. libio_grid instead of io_grid. This function, which is called by rsaga.env tries to guess this behaviour based on the operating system and SAGA GIS version.
