linux - 在 Linux 上用 g++ 编译 RInside 程序

Question

我已经通过 RPM(使用 Yast)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:

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

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

---

我是这样编译的:

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

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编译来启动所有内容？

Answer 1

尝试将以下内容添加到您的 g++ 构建的末尾

 -lRInside -lRcpp

这样你就有了

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

就目前而言，您似乎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，您似乎还没有这样做。这可能会解决问题
