https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17260 Assuming that you are the same person, I will address the issue here first. If you get the message “C++11 standard requested but CXX11 is not defined” then this means that there is no available C++11 compiler on your computer. The presence or absence of a working C++11 compiler is determined at configure time when R is built. The tests used by R's configure script to determine C++11 support are more stringent in R 3.4.0 than in previous versions. However, if you are using gcc you should be protected against this change. For versions of gcc prior to 4.8 (which have only partial C++11 support) the same tests as in R 3.3.x are used. This maintains the current behaviour on long-term service Linux distributions that are stuck with old gcc versions. It would be help if you could share more information about your platform - i.e. the output of sessionInfo() - and specify the compiler version you are using.
