Compilation flags for RcppParallel

Description

Output the compiler or linker flags required to build against RcppParallel.

Usage

CxxFlags()

LdFlags()

RcppParallelLibs()

Details

These functions are typically called from Makevars as follows:

“' PKG_LIBS += $(shell "$R_HOME/bin/Rscript" -e "RcppParallel::LdFlags()") “'

On Windows, the flags ensure that the package links with the built-in TBB library. On Linux and macOS, the output is empty, because TBB is loaded dynamically.

To ensure portability, load RcppParallel before loading your package, e.g. by including importFrom(RcppParallel, RcppParallelLibs) in your NAMESPACE file. See https://github.com/RcppCore/RcppParallel/issues/129 for details.

Value

Returns NULL, invisibly. These functions are called for their side effects (writing the associated flags to stdout).
