Rcpp (version 1.0.3)

dependsAttribute: Rcpp::depends Attribute

Description

The Rcpp::depends attribute is added to a C++ source file to indicate that it has a compilation dependency on one or more other packages. For example:

// [[Rcpp::depends(RcppArmadillo)]]

Arguments

…

Packages which the source file depends on for compilation

Details

The Rcpp::depends attribute is used by the implementation of the sourceCpp function to correctly setup the build environment for R CMD SHLIB.

The include directories of the specified packages are added to the CLINK_CPPFLAGS environment variable. In addition, if the referenced package provides an inline plugin it is called to determine additional environment variables required to successfully build.
