GNU R package clpAPI: R Interface to C API of COIN-OR Clp


The installation procedure for the clpAPI package needs to know where to
find the COIN-OR Clp include directory and where to find the callable library.


# ---------------------------------------------------------------------------- #
# Linux and MacOS X installation
# ---------------------------------------------------------------------------- #

There are basically four different ways of installing the clpAPI package:

1) Use --with-clp-<ARG>

   --with-clp-include=PATH      with PATH being the include directory of
                                COIN-OR Clp

   --with-clp-lib=PATH          with PATH being the directory containing the
                                callable library.

   R CMD INSTALL --configure-args=" \
       --with-clp-include=/path/to/include/dir \
       --with-clp-lib=/path/to/lib/dir" clpAPI_X.X.X.tar.gz


   When using --with-clp-<ARG>, both arguments must be given.

2) Use of environment variables

   PKG_CPPFLAGS                giving the PATH to the include directory of
                               COIN-OR Clp
   PKG_LIBS                    giving the PATH to the directory containing the
                               callable library.

3) Use --prefix

   --prefix=PATH               with path being the installation directory of
                               COIN-OR Clp. The include directory is assumed to
                               be PATH/include and the callable library should
                               be in PATH/lib.

   If either --with-clp-<ARG> nor --prefix is given, it is checked wether
   clp is in the PATH. If yes, PATH is used as prefix. If not,
   /usr/local/include and /usr/local/lib are tested.

3) Use pkg-config

   If pkg-config is available on your system, the pkg-config information
   of COIN-OR Clp will be used.

# Windows installation
# ---------------------------------------------------------------------------- #

For the installation on Windows systems the file Makewars.win in src/ is
required. The file looks like this:

PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I${CLP_PATH}/include/coin
PKG_LIBS=-L${CLP_PATH}/lib/coin -lClp -lCoinUtils -lstdc++

with the environment variable CLP_PATH being the installation directory
of COIN-OR Clp. This procedure was tested successfully on 32-bit Windows XP.
