Re: [Rd] Cluster: Various GCC, how important is consistency?

This absolutely causes it's own problems (and they may be bad enough that you shouldnt do it) but you can also install an older version of rcpparmadillo. My switchr package makes this more convenient from within r but grabbing tarballs from the crank Web archive also works (in fact that's what

Re: [Rd] Cluster: Various GCC, how important is consistency?

There are many issues with different gcc versions, but they can at least be minimized by using static linking, i.e. you should at the very least use -static-libstdc++ -static-libgcc to make sure you don't mix runtime versions. We run into the same problem since C++11 compilers are rare on
