r - 更新到 macOS Catalina 后无法使用 C++ 代码编译 R 包

Question

我刚刚更新到 macOS Catalina 并尝试编译 an R package我正在发展。然而，现在它不起作用了。我不确定这是因为操作系统还是因为 Rcpp 包。任何帮助将不胜感激!

您可能需要重新安装命令行工具 - Apple 通常会在操作系统更新后卸载它们。尝试运行:

xcode-select --install

在终端中。 (请注意，即使您使用 R 提供的 LLVM 工具链，它仍然需要访问默认系统 header ，并且这些 header 作为命令行工具工具链的一部分安装)

编辑:@coatless 是正确的。特别是来自https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos/ ，您需要设置 ~/.R/Makevars 以指向系统 header :

mkdir -p ~/.R

# Fill with appropriate flag statements
cat <<- EOF > ~/.R/Makevars
# clang: start
CFLAGS=-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
CCFLAGS=-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
CXXFLAGS=-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
# clang: end
EOF

请注意，R 3.6.1 修补程序默认会执行此操作 - 例如我的 $(R RHOME)/etc/Makeconf 中有:

CPPFLAGS = -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -I/usr/local/include
