RCPP无法在R 3.6.3 macOS Catalina 10.15.7上运行 [英] Rcpp not working on R 3.6.3 macOS Catalina 10.15.7

问题描述

Rcpp曾经在R上工作，但现在不再使用了，我也不知道为什么.

Rcpp used to work on R, but no longer, and I do not know why.

library(Rcpp)
evalCpp("1+1")

返回一长串错误，从

Error in sourceCpp(code = code, env = env, rebuild = rebuild, cacheDir = cacheDir,  : 
  Error 1 occurred building shared library.

继续

using ::signbit;
      ~~^
/usr/local/clang7/include/c++/v1/cmath:314:9: error: no member named 'fpclassify' in the global namespace

并以

我已经多次安装了命令行工具和Xcode.我也尝试过无衣教授"网址为 https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos-before-r-4.0.0/的解决方案(以及其他多项解决方案)，但无济于事.

I have installed command line tools and Xcode multiple times. I have also tried the "Coatless Professor" solution at https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos-before-r-4.0.0/, (as well as other multiple solutions), but to no avail.

我不愿意升级到R 4.0，因为关键的软件将无法在较新的R环境中运行.

I am reluctant to upgrade to R 4.0 because a key piece of software will stop working in the newer R environment.

推荐答案

我在Christian Herz的一篇帖子中找到了这个问题的答案，地址是: https://discourse.slicer.org/t/macos-catalina-10-15-5-compilation-error/12807/8

I found the answer to this question in a post by Christian Herz, here: https://discourse.slicer.org/t/macos-catalina-10-15-5-compilation-error/12807/8

头文件混乱，错误地将/Library/Developer/CommandLineTools 中正确头文件的符号链接副本错误地放置在/usr/local/include 中.发生此错误是由于我尝试(未成功)使用 @Roy 在此处建议的解决方案在Catalina上编译C程序的结果: https://stackoverflow.com/questions/58278260/升级到Catalina-10-15后，无法在Mac上编译AC程序.该解决方案无助于编译我的C程序，并导致Rcpp遇到困难.

Header files on my Mac were disordered, with symlinked duplicates of the correct header files in /Library/Developer/CommandLineTools incorrectly placed in /usr/local/include. This error occurred as a result of my trying (unsuccessfully) to compile a C program on Catalina using the solution suggested by @Roy here: https://stackoverflow.com/questions/58278260/cant-compile-a-c-program-on-a-mac-after-upgrading-to-catalina-10-15. The solution did not help to compile my C program and lead to the difficulties with Rcpp.

为治愈这种疾病，我遵循了@ChristofferHammarström中描述的策略 https://unix.stackexchange.com/questions/39333/how-can-i-remove-all-symbolic-links-with-a-special-target/39341#39341 并删除了所有符号链接指向/Library/Developer/CommandLineTools 的/usr/local/include 中的头文件.

To cure this ailment, I followed the strategy of @Christoffer Hammarström described in https://unix.stackexchange.com/questions/39333/how-can-i-remove-all-symbolic-links-with-a-special-target/39341#39341 and removed all symlinked headerfiles in /usr/local/include that pointed to /Library/Developer/CommandLineTools.

确切的命令是:找到/usr/local/include -lname'/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/*'-删除现在Rcpp可以正确编译了.

The exact command was: find /usr/local/include -lname '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/*' -delete and now Rcpp correctly compiles.
