Re: [R] Armadillo error in R extension
Dear Michael,
during the last days of programming I came across RcppArmadillo (Rcpp) and for
my kind of work this is indeed pretty interesting. So, I will take a closer
look today what it is about and how it works.
As a C++ programmer though, I am still interested why compilation of my package
fails at this point of code. I hope I get a little more insight on the
Rcpp-devel list suggested by Dirk!
Thanks for your comment!

My problem is the following:
I programmed a function in a header looking like
#include armadillo
inline arma::vec foo(input) {
... do something
return an arma::vec object
}
compiling this via R CMD INSTALL packagename (PKG_CXXFLAGS =
-I/folder/of/armadillo and armadillo_bits in my package)
I get the following error
error: expected initializer before 'foo'
The exact line and word is where inline arma::vec ends.
Does anyone know what this error could be?

Yes, sure -- we wrote (and use) a package RcppArmadillo that provides very
easy access to Armadillo via Rcpp.

We do. I would like to invite to subscribe to the rcpp-devel list, to peruse
its list archives, to study the RcppArmadillo examples (which cover all this)
and, if you still have questions, pose a small reproducible example on the
rcpp-devel list.
Also, we recently opened the Rcpp Gallery (http://gallery.rcpp.org) which
has a set of RcppArmadillo related posts you can read via the tags
http://gallery.rcpp.org/tags/armadillo/
Hope this helps, Dirk
