在Linux上用g++编译g++程序

Question

我已经通过RPM安装了R(与Yast一起).

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

我希望编译的文件(rinsidetest.cpp)包含：

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

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

下面是我编译它的方法：

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版本：0.2.6

Rcpp版本：0.9.13

是否有解决这个问题的方法，或者我“必须”删除rpm安装，并通过从源代码编译启动一切？。

Answer 1

尝试将以下内容添加到g++构建的末尾

 -lRInside -lRcpp

所以你有

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g++和-lXYZ链接到它，这似乎还没有完成。这可能会解决问题。

Answer 2

如果您删除新的测试文件

rinsidetest.cpp

进入包含准备好的Makefile的目录--例如examples/standard/，那么您只需说

make

并建立正确的可执行文件。它通过嵌入目录来处理运行时链接问题。

这样做的目的是让用户使用提供的Makefile，并根据需要修改/复制。
