在Linux上使用g ++编译RInside程序

问题描述

我已经通过RPM(与Yast)一起安装了R.

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

---

我要编译的文件(rinsidetest.cpp)包含:

---

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;
}

---

这是我的编译方式:

---

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

RInside version: 0.2.6
Rcpp version: 0.9.13

是否有解决此问题的方法，或者我必须"删除rpm安装并通过从源代码进行编译来启动所有内容?

推荐答案

尝试将以下内容添加到g ++版本的末尾

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

 -lRInside -lRcpp

让您拥有

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

目前看来，您似乎并没有链接到所需的库.当您有一个名为libXYZ的库时，您需要使用带有-lXYZ的g ++链接到它，看来您尚未完成.这可能会解决问题

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
