cran submission?

[tdhock]

Hey @qinwf I would like to teach a class about regular expressions in R, and it would be great if you could put re2r on CRAN, so that windows/mac users without compilers could download the binary package. Do you think you have time to do a CRAN submission some time in the next few weeks?

Ok, I will make an update and submit it to CRAN this week.

thanks for the CRAN submission. That should definitely help students with win/mac. However on my Ubuntu 14.04 machine I was getting the following

Eventually I figured out that this could be fixed by upgrading my compiler -- that was not obvious at first. If there is no explicit way to check for the right g++ version, at least I would recommend to document this issue and solution in a FAQ. Maybe add that to the README, or add it on a wiki page?

Thanks for the report! I am working on it.
