Right. Eigen is very verbose. For my local compilations I often set something like this in ~/.R/Makevars (uncommented, of course, and later in the file used in CXX*FLAGS): #PEDANTIC=-pedantic -DBOOST_NO_AUTO_PTR -Wno-ignored-attributes #PEDANTIC= -DBOOST_NO_AUTO_PTR -Wno-sign-compare -Wno-parentheses -Wno-maybe-uninitialized | but I'm not sure how to resolve | "internal::first_aligned<int(unpacket_traits<DefaultPacketType>::alignment),Derived>(m);" | which is causing the compilation error. That is worse. It seems to rely on 64bit layout. Yet is uses 'int' as opposed to 'int64_t' which would hardwire the size. Is the 'int' under your control? Can you make that an int64_t? I don't have any other suggestions. :-/ Dirk | I've tried with C++11 and C++14; same result.
