=============================================================================
INSTALLATION:
=============================================================================
1. Install SPRNG 2.0 (http:/sprng.cs.fsu.edu). Note that the
generator pmlcg requires libgmp but it provides an outdated version of
gmp.h. Find the following line in sprng2.0/SRC/pmlcg/pmlcg.c:
#include "gmp.h"
and change it to
#include <gmp.h>
to use the system header file. It won't compile otherwise.
If you encounter problems compiling SPRNG 2.0, this note
http://www.biostat.umn.edu/~nali/rsprng.html might be of help.
I have also made available some precompiled SPRNG packages at
http://www.biostat.umn.edu/~nali/SoftwareListing.html.
2. Install rsprng:
R CMD INSTALL rsprng_version.tgz
If the SPRNG header file and library file are in a non-standard path use,
R CMD INSTALL --configure-args=--with-sprng=/path/to/sprng rsprng_version.tgz
The header files of SPRNG are ssumed to be in /path/to/sprng/include and
the library .a files are in /path/to/sprng/lib. Alternative, one can also
define environment variable SPRNG_ROOT to be the path (so that R CMD check
can run).
By default pointer checking for SPRNG is enabled, to disable it, pass
'--configure-args=--disable-check-pointers' to 'R INSTALL'.
libgmp.a is needed at linking. If it is installed in a non-standard
location, you can specify it via:
R CMD INSTALL --configure-args='--with-gmp=/path/to/libgmp.a'.
