In R-1.4.1/src/nmath/standalone, in linux operating system I made 'make
shared' to obtain libRmath.so. then I copied the dir standalone, where
there is libRmath.so in /usr/local.
I tried to compile test.c with cc test.c but I obtain this error message

nmath standalone again
Hi !
I have again problem with nmath standalone sources package.
Following the suggestion of Reid, I did control that
/usr/local, in which I copied the dir standalone, is listed in
/etc/ld.so.conf.
However, because of my big ignorance, I don't understand how I have to do
the linkage to Rmath during the compilation of a source.
What does it mean:
"and link against -lRmath" in

Rmath: R libraries from C on Mac OS X
Dear R-experts,
I have been having trouble using R's standalone random number generators
from C on my Mac OS X 10.4.8 system.
I try to compile my C program in the following way:

R mathlib
Hello, dear R experts!
I run R on Debian 'sarge' platform. There is 'r-mathlib' package in
Debian distribution, which is described as:
$ dpkg --status r-mathlib

This packages provides the libRmath shared and static libraries which
can be called from standalone C or C++ code.
Well, I use runif() function in test_runif.c:

library file for R's nmath routines
Hi,
I am wondering where the library file for R's nmath routines are?
Doing a search on libR gave me the following:
/usr/lib/libRKC16.so.1.2.0
/usr/lib/libRKC.so.1.2.0
/usr/lib/R/lib/libRlapack.so
/usr/lib/R/lib/libR.so
/usr/lib/libRKC.so.1
/usr/lib/libRKC16.so.1
None of these have the functions in nmath.
Any help? Many thanks and best wishes!

unsuccesfully making libRmath.a
Dear All,
I am having problems making and using the standalone library, after succesfully
installing R from the tar.gz file (I am using Linux, with R-patched, but I have

could not open libRmath.so
Hi
I got a very tricky problem when I tried to compile a C++ program
which links to libRmath.so. The program itself had no problem, I can
compile and run in my own linux machine where I compiled libRmath.so
file and copied it to system directory (/usr/local/lib).
Now I want to compile my program at another linux box where I don't
have root privilege. That machine only has binary version of R,

compile error with C code and standalone R math C library
Dear People,
I just went back to an old piece of C code. On trying to compile it with
the R math standalone C library I got the following error. Can anyone
enlighten me what I am doing wrong, if anything? C file (rr-sa.c) follows.
I'm on Debian sarge. I'm running R version 1.8.1. Gcc is version
3.3.1.
Thanks in advance.

makefile for standalone lib
It appears the Makefile.win in
src/nmath/standalone might need some modification since
cd src/nmath/gnuwin32
make -f Makefile.win
make -f Makefile.win test
fails. However if I remove libRmath.a from line 15
OR
modify lines 67/68 replacing Rmath.a with libRmath.a then
make -f Makefile.win test
goes as expected.

The following code (using rgamma) hangs
Hi,
I'm seeing something that may be a bug in R's standalone math library,
which is packaged by Debian as r-mathlib. I reported it to the Debian BTS
as http://bugs.debian.org/657573
I'm using Debian squeeze, and the code was tested with r-mathlib 2.11.1-6
(default on stable) and 2.14.1-1 (from testing/unstable).
I summarize this report below. The following code with the R math

Catching warning message(stdout) from C
I'm using the 'pnt' C function from Rmath library in some C-code.
How can I catch the warning message: "full precision was not achieved in
'pnt'" in R. I call the function using the .C().
(options(warn=-1) didn't work)
Thanks in advance

kriging C/C++ code
Hello to everybody !
I don't have a question directly connected with R, but it takes starting
point from the use of the R function Krig for kriging interpolation and
from the idea of making a different implemetation of the function for my
purposes.
Doas anyone know where can I find free C or C++ codes of kriging ?
As always, thanks a lot in advance,
Paola.
