Greetings. I'm trying to go through some of the examples in the notes from
Dirk's Rcpp Masterclass of 28 April 2011. (I didn't take the class. I just
found the notes on the Internet. Please let me know if my use of them
violates some law or protocol. In case it makes any difference, I'm not
making any money from this project.)
I've run into a problem with the RInside "hello world" example. I can not
get it to compile on my system. The first of the many error messages is:
undefined reference to `RInside::RInside(int, char const* const*, bool)
I've appended the details. I get the same error if I omit the reference to
the c++0x standard. What am I missing?
Thanks,
-- Mike
