similar to: include C functions from nmath in my own C functions

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 ! 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, 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

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.

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"

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

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':

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. _________________________________________________________________

I see Rmath.h in include. Why can't I find libRmath.a and/or libRmath.so? -- View this message in context: http://r.789695.n4.nabble.com/where-is-libRmath-a-libRmath-so-tp2216048p2216048.html Sent from the R devel mailing list archive at Nabble.com.

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! GT

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() { // ...

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. Faheem.

Hello, Has anybody successfully called the Rmath library from C using the MS Visual Studio compiler (I am using Visual Studio 6.0)? I have compiled the Rmath library using gcc, and the 'test.c' program (which makes a call to qnorm) works fine when compiled with gcc. However, I get a fatal memory error when I run it after compiling it with Visual C. Would this memory problem be related

In the hope of some meaningful response and ignoring the risk of further abuse, let me try to clarify the issue here. I have re-read the 'Writing R Extensions' manual. It seems to me that it clearly says R API functions can be called from from C++ programs, and the API includes the special values ISNAN() and R_FINITE() and the missing test ISNA(). R_FINITE is no problem. It is

Dear People, I am trying to use R's Math library as standalone, as documented in /src/nmath/standalone. I am using C++ in Debian testing, and the versions are as follows: ii g++-3.0 3.0.3-1 The GNU C++ compiler. ii r-mathlib 1.4.0-1 `GNU S' - Standalone R math library I have a file (rand.cc) as follows. I don't think that lattice.hh or mh.hh are very

Hi folks, I'm trying to call an R function (fisher.test) in my program for like a billion times! Though my program is in Python and I feel that using rpy2 to interface R to python doesn't give me satisfactory performance. So I looked into R code and found out that fisher.test is actually a wrapper around another function called fexact which is implemented in C. Using Cython I managed to
