Get Configures Used at Compiling Time: Functions to Get MPI and/or pbdMPI Configures Used at Compiling Time

Description

These functions are designed to get MPI and/or pbdMPI configures that were usually needed at the time of pbdMPI installation. In particular, to configure, link, and compile with `libmpi*.so` or so.

Usage

get.conf(arg, arch = '', package = "pbdMPI", return = FALSE)
get.lib(arg, arch, package = "pbdPROF")
get.sysenv(flag)

Value

Typically, there are no return values, but the values are cat() to scrrn or stdin.

Arguments

arg

an argument to be searched in the configuration file

arch

system architecture

package

pakge name

return

to return (or print if FALSE) the search results or not

flag

a system flag that is typically used in windows environment set.

Details

get.conf() and get.lib() are typically used by `pbd*/configure.ac`, `pbd*/src/Makevars.in`, and/or `pbd*/src/Makevar.win` to find the default configurations from `pbd*/etc${R_ARCH}/Makconf`.

get.sysenv() is only called by `pbdMPI/src/Makevars.win` to obtain possible MPI dynamic/static library from the environment variable `MPI_ROOT` preset by users.
