我在 Mac OS X（14.3.1，截至本文安装了最新版本的 Xcode 工具）上遇到了 Rcpp 错误。我过去广泛使用过 Rcpp，但大约有一年没有使用过，所以我不确定这个编译问题是什么时候出现的。
这是一个可重现的示例：

如果有任何帮助，我将不胜感激！
这很可能是您的 R 安装配置错误。例如尝试这些命令（我正在 R 容器中执行此操作）
# R CMD config CC
gcc
# R CMD config CXX
g++ -std=gnu++17
# R CMD config CXXFLAGS
-g -O2 -ffile-prefix-map=/build/reproducible-path/r-base-4.3.3=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -Wdate-time -D_FORTIFY_SOURCE=2

我强烈怀疑您看到的选项来自您的 R 安装（因此在 Unix 系统上对其进行
less $(R RHOME)/etc/Makeconf~/.R/MakevarsRcpp 没有这些选项，因为您可以在存储库中快速检查：
