question about /nmath/standalone
....) The library is not built automatically when R is installed, but can be built in the directory 'src/nmath/standalone? in the R sources: see the file 'README? there. To use thecode in your own C program include #define MATHLIB_STANDALONE #include <Rmath.h> and link against '-lRmath?. There is an example file 'test.c?." Have I to do: gcc -lRmath test.c ? In this case I receive this message: > /usr/bin/ld: cannot find -lRmath > collect2: ld returned 1 exit status " what should I do? or I do something before I use "gcc -lRmath test.c" to compi...

nmath standalone again
...uggestion 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 file README of src/nmath/standalone ? Have I to do: cc -lRmath test.c ? In this case I receive this message: /usr/bin/ld: cannot find -lRmath collect2: ld returned 1 exit status I ask again your help. Sorry for the disturb.

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: 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 built on my Mac OS X installation. Any pointers (perhaps to a step by step guide for a _beginner_ on how to install this and th...

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() { // ... printf("%f\n", runif(0, 1)); } and compile it: $ gcc -I/usr/lib/R/include -lRmath -lm -o test_runif test_runif.c /tmp/ccmICWeD.o(.text+0x2d): In function `main': : undefined reference to `Rf_runif' collect2: ld returned 1 exit status Replacing `-lm' with `-lR' solves the problem. So, I need libR.so anyway? Thanks. -- WBR, Timur

Problems when linking to R shared library

I've tried this on both Windows with the precompiled Mingw binary of R-2.5.0 (compiling my code with MinGW-3.4.2), and by building R-2.5.0 on Mandriva Linux with gcc-3.4.4 and
