[Rcpp-devel] Undefined Reference to typeinfo for Rcpp::RObject for Rdisop on Mac after Rcpp/RcppClassic update

[Steffen Neumann]

Hi list,

I am having issues to build Rdisop on Mac (to which I have no access)
after the upgrade to Rcpp 0.11.0 / RcppClassic 0.9.5, on both 

http://bioconductor.org/checkResults/2.13/bioc-LATEST/Rdisop/perceval-buildsrc.html
http://bioconductor.org/checkResults/2.14/bioc-LATEST/Rdisop/petty-buildsrc.html

with the same error message. Somehow the "typeinfo for Rcpp::RObject"
is not found in the shared library:

	Symbol not found: __ZTIN4Rcpp7RObjectE (typeinfo for Rcpp::RObject)
	Expected in: flat namespace

Any idea how to get back it in there ? This sounds similar 
to [1] and [2] and would hint that "someone" 
(R ? BioC build farm ?) needs to set (at compile time[3])

	export REQUIRES_RTTI=1

Thanks in advance,
Yours,
Steffen

The system is petty:
http://bioconductor.org/checkResults/2.14/bioc-LATEST/petty-NodeInfo.html
with Mac OS X Snow Leopard (10.6.8), 
R Under development (unstable) (2014-01-15 r64790) -- "Unsuffered Consequences" 
and llvm-g++-4.2 compiler.

Installed packages here are:
http://bioconductor.org/checkResults/2.14/bioc-LATEST/petty-R-instpkgs.html
Rcpp                                            0.11.0 3.1.0
RcppClassic                                      0.9.5 3.1.0


[Don't mind the windows build failure, that comes next, 
 but it only happens on one machine so it works somewhere.]


** testing if installed package can be loaded
