Dealing with Catalina III

Interfaces RStan
5

I installed rstan on Catalina today following all previous instructions. Everything works perfectly fine and straightforward if I simply ignore the extra Makevars component in the “Manual Install Guide”:

Note: If you are on macOS Mojave (10.14) or higher, you will need to add into ~/.R/Makevars a set of compilation flags.

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

SHLIB_CXXLDFLAGS+=-Wl,-rpath,\${R_HOME}/lib \${R_HOME}/lib/libc++abi.1.dylib
SHLIB_CXX14LDFLAGS+=-Wl,-rpath,\${R_HOME}/lib \${R_HOME}/lib/libc++abi.1.dylib
# clang: end
