makevars: User and Site Compilation Variables
Description
Determine the location of the user and site specific Makevars
files for customizing package compilation.Usage
makevars_user()
makevars_site()
Value
A character string with the path to the user or site specific
Makevars
file, or an empty character vector if there is no such
file.Details
Package maintainers can use these functions to employ user and site
specific compilation settings also for compilations not using R's
mechanisms (in particular, custom compilations in subdirectories of
src
), e.g., by adding configure code calling R with
cat(tools::makevars_user())
or
cat(tools::makevars_site())
, and if non-empty passing this with
-f to custom Make invocations.See Also
Section “Customizing package compilation” in the
“R Installation and Administration” manual.
