Hi Dirk and James,
Yes, I think this is a great idea
"One idea could be to put something basic in the Rcpp FAQ and maybe
link to
the wiki within the Rcpp repo -- which we basically don't use at all
right
now -- to have a more dynamic reference too. Thoughts?"
I think that "something basic" (like simply put the URL in the Rcpp FAQ) will
be just fine. The idea is just to direct the OS X use that experienced "my"
problem in the right direction.
Thanks again.
Anguel Grigorov

Anguel,
Thanks for taking the time to report back -- appreciated.

Seconded.

Yes -- right after James posted this I asked him off-list to take a look at
what is currentlyn the Rcpp FAQ, which he very kindly agreed to do. The
version is the package is stale-est, the one on GitHub received a recent
updated -- but all this needs work. I'll also ping other OS X users like
Kevin or Bob Rudis (who, if memory serves, recently wrote a 'R on OS X'
checklist/howto).

Absolutely. I am spoiled because things tend to 'just work' on Linux [1] so
we all need to keep an eye on current and helpful OS X documentation. Ditto
for Windows but Rtools is a bit standard(ized) already.

[1] That is unless Ubuntu fscks up clang++ header use, but then again I
mostly use g++.

| Hi everyone,
|
| My name is Anguel and I am new to this list.
|
| 1. I am trying to implement some simple example of a C++ compiled function
| from Hadley Wickham's website (http://adv-r.had.co.nz/Rcpp.html#rcpp).
| In fact the function I am trying to compile is the first one:
|
| library(Rcpp)
| cppFunction('int add(int x, int y, int z) { int sum = x + y + z; return
sum;}')
|
|
|
|
|
| 2. Unfortunately I have immediately run into a problem, getting an error
message:
