thanks for the heads up. I will have a look at what needs to be done in
a few days.

hi. i normally build under macosx, but trying to track down a memory
problem have started using (the wonderful) valgrind under linux. the
linux machine has a newer g++ (4.7.2 versus 4.2.1). the compiler on
the
linux machine was giving me warnings like:
----
warning: deleting object of polymorphic class type
‘Rcpp::CppProperty<Num>’ which has non-virtual destructor might cause
undefined behaviour
----
(where "<Num>" varies between error messages).
i started whittling down my program to a minimal case, but when i got
near the null set, took a different approach. i used the normal
tools
to build a skeleton:
----
/sw/Library/Frameworks/R.framework/Versions/2.15/Resources/Rscript -e
\
'Rcpp::Rcpp.package.skeleton(name="play", path="packages", \
attributes=TRUE, module=TRUE)'
/sw/Library/Frameworks/R.framework/Versions/2.15/Resources/Rscript -e
\
'Rcpp::compileAttributes("packages/play")'
R CMD build packages/play/
----
i then copied this to the linux machine, tried installing it, and got
the same (sorts of) error messages (see below).
note that my ~/.R/Makevars contains:
----
## http://stackoverflow.com/a/11363085/1527747 (thanks, Dirk!)
CXXFLAGS=-g -O0 -Wall
----
since this is C++ at a level beyond my pay grade, i'm wondering what
to
make of it. any thoughts? (in the case of my code, there is *some*
correlation between the sites producing these warnings and the sites
where valgrind finds memory irregularities, but that may be
coincidental.)
cheers, Greg
