我想在 c++x11 代码中使用 RInside 来调用 R 例程。默认情况下,R 似乎安装了库的 c++98 版本,因此链接不成功。我想知道我应该执行哪些不同的步骤来安装 RInside 的 c++x11 版本(但我想我需要重新编译所有 R/R 包,是吗?)以及是否存在一些更简单的解决方案。在此先感谢(我在 MacO 上工作)
更新:我重新安装了 Rcpp 和 RInside (我的 Makevars 是空的,所以 c++98 版本)
sudo R CMD INSTALL ~/Downloads/Rcpp_0.10.4.tar.gz
sudo R CMD INSTALL ~/Downloads/RInside_0.2.10.tar.gz
然后我使用 (no cx11) 编译 hello world 示例:
clang++ -I/Library/Frameworks/R.framework/Versions/2.15/Headers/ -I/Library/Frameworks/R.framework/Versions/2.15/Resources/library/RInside/include/ -I/Library/Frameworks/R.framework/Versions/2.15/Resources/library/Rcpp/include/ -c ../src/Gui/test.cc -o testOut.cc.o
clang++ testOut.cc.o -o testOut -L/Library/Frameworks/R.framework/Versions/2.15/Resources/library/RInside/lib/x86_64 -L/Library/Frameworks/R.framework/Versions/2.15/Resources/library/Rcpp/lib/x86_64 -framework R -lRInside -lRcpp
这产生了我:
Hello, world!
但是,通过添加 x11 选项:
clang++ -I/Library/Frameworks/R.framework/Versions/2.15/Headers/ -I/Library/Frameworks/R.framework/Versions/2.15/Resources/library/RInside/include/ -I/Library/Frameworks/R.framework/Versions/2.15/Resources/library/Rcpp/include/ -c ../src/Gui/test.cc -o testOut.cc.o -stdlib=libc++ -std=c++11
clang++ testOut.cc.o -o testOut -L/Library/Frameworks/R.framework/Versions/2.15/Resources/library/RInside/lib/x86_64 -L/Library/Frameworks/R.framework/Versions/2.15/Resources/library/Rcpp/lib/x86_64 -framework R -lRInside -lRcpp -stdlib=libc++ -std=c++11
我得到(链接时):
Undefined symbols for architecture x86_64:
"RInside::parseEvalQ(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)", referenced from:
_main in testOut.cc.o
"RInside::operator[](std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)", referenced from:

使用 c++x11 选项重新编译 Rcpp 和 RInside 时
clang++ -I/Library/Frameworks/R.framework/Versions/2.15/Headers/ -I/Library/Frameworks/R.framework/Versions/2.15/Resources/library/RInside/include/ -I/Library/Frameworks/R.framework/Versions/2.15/Resources/library/Rcpp/include/ -c ../src/Gui/test.cc -o testOut.cc.o -stdlib=libc++ -std=c++11
clang++ testOut.cc.o -o testOut -L/Library/Frameworks/R.framework/Versions/2.15/Resources/library/RInside/lib/x86_64 -L/Library/Frameworks/R.framework/Versions/2.15/Resources/library/Rcpp/lib/x86_64 -framework R -lRInside -lRcpp -stdlib=libc++ -std=c++11
喜欢是可以的,但 ./test 给了我一个段错误。
添加:我的clang版本是:Apple clang 4.1版(tags/Apple/clang-421.11.66)
