This seems to output "CXX17" on a machine with no C++17 support. On the
other hand, running `${R_HOME}/bin/R CMD config CXX17` here gives me an
empty string.
Actually, you are right -- from the shell it does return a string. I'll try the alternative version. THK
Not on my machine. But perhaps this is the issue with Solaris? You can check the comments at https://github.com/eddelbuettel/rcppsimdjson/blob/master/configure that suggest the grep method is more robust. But perhaps that's no longer the case or on all platforms. THK
