[Rcpp-devel] g++-llvm still doesn't like RcppArmadillo?

[Davor Cubranic]

Did we ever find a way to make RcppArmadillo compile with g++-llvm 
on OS X Lion?

There was a thread in July about unresolved 'arma_version' symbol 
(http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2011-July/002621.html), 
and it appears the only way around it was by compiling with the 
vanilla g++.

I just ran into the same error, using R installed from MacPorts as 
the R-framework port. This uses the llvm-g++-4.2 toolchain, so 
getting it to use apple-g++ to compile just RcppArmadillo would 
probably require manual fiddling with the configure step, which I 
would prefer to avoid given that this is on a compute cluster where 
we're automating software installation and upgrading.

Also, does anyone know if this will mean that every package that 
depends on RcppArmadillo will have to avoid using LLVM as well?
