LINK Create Executable Programs on Unix-alikes

Description

Front-end for creating executable programs on unix-alikes, i.e., not on Windows.

Usage

R CMD LINK [options] linkcmd

Arguments

linkcmd	a list of commands to link together suitable object files (include library objects) to create the executable program.
options	further options to control the linking, or for obtaining information about usage and version.

Details

The linker front-end is useful in particular when linking against the R shared or static library: see the examples.

The actual linking command is constructed by the version of libtool installed at ‘R_HOME/bin’.

R CMD LINK --help gives usage information.

Note

Some binary distributions of R have LINK in a separate bundle, e.g. an R-devel RPM.

This is not available on Windows.

Examples

## Not run: ## examples of front-ends linked against R.
## First a C program
CC=`R CMD config CC`
R CMD LINK $CC -o foo foo.o `R CMD config --ldflags`

## if Fortran code has been compiled into ForFoo.o
FLIBS=`R CMD config FLIBS`
R CMD LINK $CC -o foo foo.o ForFoo.o `R CMD config --ldflags` $FLIBS

## And for a C++ front-end
CXX=`R CMD config CXX`
R CMD COMPILE foo.cc
R CMD LINK $CXX -o foo foo.o `R CMD config --ldflags`

## End(Not run)
