You need to have CXX14FLAGS and CXX14 set like CXXFLAGS and CXX in your ~/.R/Makevars .

The same error with

CXXFLAGS=-O3 -std=c++1y -mtune=native -march=native -Wno-unused-variable -Wno-unused-function

CC=clang
CXX=clang++ -arch x86_64 -ftemplate-depth-256

CXX14=clang++ -arch x86_64 -ftemplate-depth-256 
CXX14FLAGS=-O3 -std=c++1y -mtune=native -march=native -Wno-unused-variable -Wno-unused-function

EDIT: I thought for macOS CXX14 will be set by installation process.

What is your clang++ version? The R installer for Mac does not set CXX14 but the recommended toolchain installer does.

bash-3.2$ clang++ --version

Do you have any idea why it refers to something at StanHeaders/include/src/stan/lang/ast_def.cpp:738:30 which only has 122 lines?

7

That’s confusing me tool. All the files in the include are of wrong version. Let me dig into my git setting.

8

Did you install StanHeaders from CRAN or from GitHub?

9

From github.

10

OK, try install.packages("StanHeaders") to get it from CRAN.

that solves it. I must have pull a wrong branch. Thanks.
