StanHeaders (version 2.39.1)

CxxFlags: Compilation flags for StanHeaders

Description

Output the compiler or linker flags required to build with the StanHeaders package

Usage

CxxFlags(as_character = FALSE)
  LdFlags(as_character = FALSE)

Value

If as_character is TRUE, then these functions return a character vector of length one. Otherwise, (which is the default) these functions return NULL invisibly after outputing the compiler or linker flags to the screen.

Arguments

as_character

A logical scalar that defaults to FALSE that indicates whether to return the compiler or linker flags as a character vector of length one. Otherwise, the compiler or linker flags are merely output to the screen, which is appropriate when called from a Makevars or Makevars.win file

Details

These functions are currently not exported and are typically called from a Makevars or a Makevars.win file of another package as follows:

PKG_CXXFLAGS += $(shell "${R_HOME}/bin/Rscript" -e "StanHeaders:::CxxFlags()") PKG_LDLIBS += $(shell "${R_HOME}/bin/Rscript" -e "StanHeaders:::LdFlags()")
