CXX14 error when trying to install #1

I'm trying to install via devtools::install_github("cmu-delphi/epiforecast-R", subdir="epiforecast") but am getting the following error:

I've installed and updated all of the dependecies the package requires, but can't get over the final hurdle. Any thoughts on how to resolve or a potential workaround? Pasting my session_info() below if that is useful at all:

Sorry I did not see this earlier. The C++14-reliant code (the EB forecaster) has been moved to a separate package for now so it is easier to use the remainder of the package functionality.

If you still need to use the EB code, you should expect to run into the same error message when installing the C++14-reliant package. This issue may arise from not having a recent enough C++ compiler. One way to check this is to do: $ g++ --std=c++14 And see if it produces "g++: error: unrecognized command line option 'std=c++14' [...]" in addition to the expected error message "g++: fatal error: no input files".

If g++ doesn't recognize --std=c++14 then you may be able to resolve the issue by upgrading your g++. Sorry, we've talked about resolving this by removing reliance on c++14 features, but it's not a priority right now.

Awesome thanks. At this point I only need the code to fetch Epidata and mimic past Epidata, so this works and I'll leave the C++ issues for another day.
