g ++ ld找不到用于x86_64体系结构的RInside符号 [英] g++ ld can't find RInside symbols for x86_64 architecture
问题描述
我得到一个链接器错误，说当我尝试使用g ++编译RInside示例文件时，无法找到符号。任何帮助将不胜感激。
I get a linker error saying that symbol(s) cannot be found when I try to compile an RInside sample file with g++. Any assistance would be appreciated.
R版本2.13.1安装在Mac OS X 10.5上。 Rcpp和RInside包含文件已经复制到usr / include目录。 R头文件和库已经使用g ++的-I和-L修饰符包含，如下所示：
R version 2.13.1 is installed on Mac OS X 10.5. Rcpp and RInside include files have been copied to the usr/include directory. R headers and libraries have been included using the -I and -L modifiers of g++ as shown:
$g++ -I/Library/Frameworks/R.framework/Headers -L/Library/Frameworks/R.framework/Libraries rinside_sample0.cpp
rinside_sample0.cpp文件是RInside软件包提供的示例，如下所示：
The rinside_sample0.cpp file is a sample provided with the RInside package, shown below:
// -*- mode: C++; c-indent-level: 4; c-basic-offset: 4; tab-width: 8; -*-
//
// Simple example showing how to do the standard 'hello, world' using embedded R
//

// Copyright (C) 2010 Dirk Eddelbuettel and Romain Francois
//
// GPL'ed
#include <RInside.h> // for the embedded R via RInside
int main(int argc, char *argv[]) {
RInside R(argc, argv); // create an embedded R instance
R["txt"] = "Hello, world!\n"; // assign a char* (string) to 'txt'
R.parseEvalQ("cat(txt)"); // eval the init string, ignoring any returns
exit(0);
}
当我尝试用g ++编译时，得到一个错误，如下所示： / p>
When I attempt to compile with g++ I get an error, shown below:
ld: symbol(s) not found for architecture x86_64
有人可以告诉我我做错了什么以及如何解决它？
Can someone tell me what I'm doing wrong and how to fix it? Any assistance would be appreciated.
推荐答案
您使用的编译器（似乎64位）和库之间有一个不匹配显然是32位），这使得链路尝试失败。最简单的解决方案是从源重新安装Rcpp和RInside;它将为编译器重新创建文件（大概是64位）。
You have a mismatch between the compiler used (seemingly 64-bit) and the library found (apparently 32-bit) which makes the link attempt fail. The easiest solution is probably to re-install both Rcpp and RInside from sources; that will recreate files for the compiler (presumably 64-bit).
正常构建能力的Proof由CRAN检查提供如在Windows检查中修补此补丁，您甚至可以自己上传到 win-builder 。
"Proof" of normal ability to build is provided by the CRAN checks as eg this R-patched on Windows check, and you could even upload to win-builder yourself.
rcpp-devel列表可以进一步帮助这一点，因为几个OS X用户正在阅读它。我似乎记得在OS X从源代码是建议的解决方案，但它是我的合作者谁在OS X上工作，而不是我：）
The rcpp-devel list can be of further assistance with this as several OS X users are reading it. I seem to recall that on OS X builds from source are the recommended solution but it is my coauthor who works on OS X not me :)
