RInside示例构建使用clang ++在OS X上Mavericks无法找到STL标准库链接 [英] RInside example build using clang++ on OS X Mavericks cannot find STL standard library on linking

问题描述

我最近使用OS X 10.9.1的命令行工具移动到C ++ 11和Xcode 5，使用Homebrew安装了boost 1.55，并将编译器从g ++更改为clang ++（如本帖中所述：使用Xcode 5.0和Rcpp时出错 ）。编译器在R中运行时改变了固定的Rcpp。但是我在编译RInside例子时遇到问题（以前工作正常）。

I recently moved to C++11 and Xcode 5 with command line tools on OS X 10.9.1, installed boost 1.55 using Homebrew and changed the compiler from g++ to clang++ (as mentioned in this post: Error when with Xcode 5.0 and Rcpp). The compiler change fixed Rcpp when running in R. But I am having issues with compiling the RInside examples (which used to work just fine).

我重新下载RInside解压缩tar，转到examples / standard目录，并做了 make clean 和 make all 。看起来任何STL没有链接到这个目录。如何使RInside链接到合适的STL在Makefile？

I re-downloaded RInside and unzipped the tar, went to the examples/standard directory and did a make clean and make all. It looks like any STL is not being linked to from this directory. How do I make RInside link to the appropriate STL in the Makefile?

我在一个单独的项目中使用来自Netbeans的STL，并使用clang ++工作。但是，当我尝试在Netbeans RInside项目，我得到同样的问题：架构x86_64 未定义的符号。我需要下载64位版本的STL或RInside某处吗？

I am using STL from Netbeans in a seperate project and building using clang++ works there. However, when I try an RInside project on Netbeans I get the same issue: Undefined symbols for architecture x86_64. Do I need to download a 64 bit version of STL or of RInside somewhere ?

我仍然需要更新/更改配置某处，我下载错误的包

Am I still in need of updating/altering a config somewhere, did I download a wrong package or is it a setting in the Makefile for the examples that needs to change?

这里是中的第一个调用make all ：

clang++ -I/Library/Frameworks/R.framework/Resources/include -I/Library/Frameworks/R.framework/Versions/3.0/Resources/library/Rcpp/include -I/Library/Frameworks/R.framework/Versions/3.0/Resources/library/RInside/include -mtune=native -g -O2 -Wall -pedantic -Wconversion -Wall -I/usr/local/include   rinside_callbacks0.cpp  -F/Library/Frameworks/R.framework/.. -framework R  -L/Library/Frameworks/R.framework/Resources/lib -lRblas -L/Library/Frameworks/R.framework/Resources/lib -lRlapack /Library/Frameworks/R.framework/Versions/3.0/Resources/library/Rcpp/lib/libRcpp.a /Library/Frameworks/R.framework/Versions/3.0/Resources/library/RInside/lib/libRInside.a -o rinside_callbacks0

输出的开头：

错误消息：

clang: error: linker command failed with exit code 1 (use -v to see invocation)

推荐答案

我得到了一个例子，从我的Netbeans工作后，降级到Xcode 4.6.3在OS X 10.9.1和使用clang ++和C + + 11（没有其他更改的设置在Netbeans）。它也工作在g ++（或clang ++）使用C ++ 98。看起来像Xcode 5中的默认库是 libc ++ （LLVM C ++标准库，支持C ++ 11），但我需要链接的是 libstdc ++ （GNU C ++标准库 - 早期Xcode版本的默认库）。在〜/ .R / Makevars文件中修改了之后 CXXFLAGS = - stdlib = libstdc ++ -std = c ++ 11 -mtune = native -g -O3 -Wall -pedantic -Wconversion以及 clang ++ 更改我得到了要构建的示例。我通过重新升级到Xcode 5并在Netbeans中获得相同的错误，而不是在样例（现在由于 libstdc ++ 标志构建）上确认了这种行为。当我添加 -stdlib = libstdc ++ 作为Netbeans中的附加标志时，它再次构建。

I got the example to work from my Netbeans after downgrading to Xcode 4.6.3 on OS X 10.9.1 and using clang++ and C++11 (no other changes to the settings in Netbeans). It also worked on g++ (or clang++) using C++98. It looks like the default library in Xcode 5 was libc++ (LLVM C++ standard library with C++11 support) but what I needed for this to link was libstdc++ (GNU C++ standard library - default library for earlier Xcode versions). After changing that in the ~/.R/Makevars file CXXFLAGS="-stdlib=libstdc++ -std=c++11 -mtune=native -g -O3 -Wall -pedantic -Wconversion" along with the clang++ change I got the examples to build. I confirmed the behavior by re-upgrading to Xcode 5 and getting the same error in Netbeans but not on the samples (which now built because of the libstdc++ flag). When I added -stdlib=libstdc++ as an additional flag in Netbeans it built again.

其他人打了一个问题建立示例。在Netbeans中，编译和链接步骤是：

Just as an fyi in case someone else hits a problem building the examples. In Netbeans the compile and links steps are:

"/Applications/Xcode.app/Contents/Developer/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
"/Applications/Xcode.app/Contents/Developer/usr/bin/make"  -f nbproject/Makefile-Debug.mk dist/Debug/GNU-MacOSX/callingrproject
mkdir -p build/Debug/GNU-MacOSX
rm -f "build/Debug/GNU-MacOSX/main.o.d"
clang++ -stdlib=libstdc++   -c -g -I. -I/Library/Frameworks/R.framework/Resources/include -I/Library/Frameworks/R.framework/Resources/library/Rcpp/include -I/Library/Frameworks/R.framework/Resources/library/RInside/include -I/usr/local/Cellar -std=c++98 -MMD -MP -MF "build/Debug/GNU-MacOSX/main.o.d" -o build/Debug/GNU-MacOSX/main.o main.cpp

示例build是：
