Compiling RInside program with g++ on Linux

Question

I have installed R through RPM (with Yast).

anisha@linux-y3pi:~> locate RInside.so
/usr/lib64/R/library/RInside/lib/libRInside.so
/usr/lib64/R/library/RInside/libs/RInside.so

anisha@linux-y3pi:~> locate Rcpp.so
/usr/lib64/R/library/Rcpp/lib/libRcpp.so
/usr/lib64/R/library/Rcpp/libs/Rcpp.so

---

The file (rinsidetest.cpp) that I wish to compile contains:

#include <RInside.h>
#include <Rcpp.h>

int main (int argc, char *argv[])
{
    RInside R (argc, argv);
    return 0;
}

---

Here's how I compile it:

anisha@linux-y3pi:~> g++ rinsidetest.cpp -I /usr/lib64/R/library/RInside/include/ -I /usr/lib64/R/library/Rcpp/include/ -I /usr/lib64/R/include/ -L /usr/lib64/R/library/RInside/libs/ -L /usr/lib64/R/library/Rcpp/libs/ 

/tmp/ccUfdjgZ.o: In function `main':  
rinsidetest.cpp:(.text+0xb7): undefined reference to `RInside::RInside(int, char const* const*, bool)'  
rinsidetest.cpp:(.text+0xc8): undefined reference to `RInside::~RInside()'  
collect2: ld returned 1 exit status

Is there a workaround for this problem, or I "have to" remove the rpm installation and start everything by compiling from source?

Answer 1

Try adding the following to the end of your g++ build

 -lRInside -lRcpp

so that you have

g++ rinsidetest.cpp -I /usr/lib64/R/library/RInside/include/ -I /usr/lib64/R/library/Rcpp/include/ -I /usr/lib64/R/include/ -L /usr/lib64/R/library/RInside/libs/ -L /usr/lib64/R/library/Rcpp/libs/ -lRInside -lRcpp

As it stands it doesnt appear that you are linking to the library you need. When you have a library named libXYZ you need to link to it using g++ with -lXYZ which it appears you have not done. This may fix the problem

Answer 2

If you drop your new test file

rinsidetest.cpp

into a directory containing the prepared Makefile -- as eg examples/standard/, then you only need to say

make

and the correct executable will be built. It takes care of the run-time linking issue by embedding the directory.

The idea is for users to take the provided Makefile, and adapt/copy as needed.
