Hi: I followed the README in src/nmath/standalone/ to make the use the command "make shared" to make the libRmath.so file. I also add the directories containg libRmath.so to LD_LIBRARY_PATH by using command "export D_LIBRARY_PATH=$LD_LIBRARY_PATH:$/home/zhliu/Backup/R-2.0.1/src/nmath/standalon e " However, when I try to run the following codes by the command

Hi, I have read R's Writing Extensions manual and am still confused about how to use some of the routines there when I call from C. Specifically, I am writing a little test function which I will optimize using the nmmin function which underlies R's optim() with Nelder-Mead. I guess I wonder what library/header files I should be using. I was using R_ext/Applic.h and linking with libR but I

Hello, all, I have the same question as the last mail I sent. I have installed libRmath in my system. But I still can not link Rmath through -lRmath. The whole process is as follow.Is there anybody who is so kind to help me find out the problem? I will appreciate very much. [credsim at confsys ~]$ cd /usr/lib [credsim at confsys lib]$ ls -l libR* -rw------- 1 bcdesai bcdesai 237828 Apr

Dear all, I'm trying to use the as a standalone package the nmath sources. 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 /tmp/ccsTxu7U.o: In function `main':

Hi ! 1) First question. Excuse me for trouble with the same question. I still have problems with the compilation of test.c in src/nmath/standalone. I did follow the instructions you gave me but I still receive this message [root at my standalone]# cc -o test test.c -L/usr/local -lRmath /usr/local/libRmath.so: undefined reference to `log' /usr/local/libRmath.so: undefined reference to

Hello, I can't link a c code with Mathlib according to introduction of R manual "Writing R Extensions", page 60. It is written : "It is possible to build Mathlib, the R set of mathematical functions documented in 'Rmath.h?, as a standalone library 'libRmath? under Unix and Windows. (This includes the functions documented in Section 5.7 [Numerical analysis

Hello, I forgot to tell you that I am using Linux OS. And I can?t find directory "src/nmath/standalone". I will send you the test code I am using and the whole operation process.

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. _________________________________________________________________

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 similar problems with R-devel). First, when I do: root at ligarto:/usr/lib/R-patched/src/nmath/standalone > make .... ar: mlutils.o: No such file or directory make[1]: *** [libRmath.a] Error 1 make[1]: Leaving directory

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: gcc -Wall -o helloMac helloMac.c -lm -lRmath I get the following error: /usr/bin/ld: can't locate file for: -lRmath I am unable to locate Rmath on my machine. The problem appears to be that no libRmath.a was

Hi, I am a new CentOS user (quite familiar with Fedora 1-23+) and I decided to try a new install of CentOS on a ASUS R503U. However, I can not get hibernate to work. I try: systemctl hibenaate and I get: Failed to execute operation: sleep verb not supported Btw, the problem does not go away with super-user. I was wondering how to get around this issue. I would like the abililty to hibernate

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: #include <Rmath.h> main() { // ...

Hi, It is my understanding that the eigenvectors of a circulant matrix are given as follows: 1,omega,omega^2,....,omega^{p-1} where the matrix has dimension given by p x p and omega is one of p complex roots of unity. (See Bellman for an excellent discussion on this). The matrix created by the attached row and obtained using the following commands indicates no imaginary parts for the

Hi: I am writing a C program which need a gamma random number generator. I download the source file of R and compile, make it myself. There is a "rgamma.c" function in the installing directory of R("/home/zhliu/Backup/R-2.0.1/src/nmath/rgamma.c"). My question is how to call this function in my own program which is in another directory. I can not copy this "rgamma.c"

Hi, Thanks, everyone for all the help! So, here is my calling function in C (called test.c): #include<stdio.h> #include<stdlib.h> #include<Rmath.h> int main(void) { printf("%f \n",pchisq(2.,7., 1, 0)); printf("%f \n",pnchisq(2.,7.,0., 1, 0)); return EXIT_SUCCESS; } I compile using: gcc test.c -I/usr/lib/R/include

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
