我正在尝试在 R 中编译 C++ 代码，以便可以从源代码安装包。我在 Mac OS X Catalina (10.15.6) 上运行 R 4.0.2。我已按照此处Rcpp的说明在 Mac OS 上安装 R 编译器工具。但是，按照说明操作时，尝试在 R 中编译以下 C++ 代码（另存为 ）时收到错误消息/Users/itpetersen/Desktop/helloworld.cpp：

#include <RcppArmadillo.h>   

// [[Rcpp::depends(RcppArmadillo)]]

// [[Rcpp::export]]
void hello_world() {
  Rcpp::Rcout << "Hello World!" << std::endl;  
}

// After compile, this function will be immediately called using
// the below snippet and results will be sent to the R console.

/*** R
hello_world() 
*/

这是我尝试在 R 中编译上述 C++ 代码时收到的错误：

> Rcpp::sourceCpp('/Users/itpetersen/Desktop/helloworld.cpp')
helloworld.cpp:1:10: fatal error: 'RcppArmadillo.h' file not found
#include <RcppArmadillo.h>   
         ^~~~~~~~~~~~~~~~~

Error in Rcpp::sourceCpp("/Users/itpetersen/Desktop/helloworld.cpp") :

尝试从源代码编译包时，我也收到错误mirt消息：

这是我所做的：

  • 我在以下位置删除了文件：~/.R/Makevars
  • 我在以下位置删除了文件：~/.Renviron
  • 我安装了Xcode11.6 版
  • 我通过输入终端验证了Xcode安装。gcc --version这是输出：
gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.3 (clang-1103.0.32.62)

  • 我从这里gfortran安装了8.2 版
  • 我在 R 中安装了Rcpp和RcppArmadillo包
  • 我还尝试将文件夹中的内容复制到include文件RcppArmadillo夹中的include文件Rcpp夹中（如此处所建议），但在尝试编译 C++ 代码时继续收到错误（尽管是不同的错误）
  • 我也在这里尝试了 StackOverflow 上类似问题的解决方案，但他们没有解决问题。请注意，我使用的 R 版本比其他问题更新，因此我的问题不应被视为重复问题。
