[Rcpp-devel] RcppEigen needs 1GB memory to compile

[Douglas Bates]

The important thing is to use the -g0 flag.  Even though RcppEigen is  a
header-only package we include an example R function fastlm. If you leave
the symbols in the DLL file you get a massive library size whereas
stripping the symbols provides you with a much smaller file size.  And
because packages that use RcppEigen only use the headers, not the DLL file,
it doesn't matter if the symbols are stripped.
