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

[Jeroen Ooms]

I noticed that RcppEigen fails to install on my servers because it requires
more than 1gb of memory to compile. Is this expected? Are there any flags
or options I could set to trade of some memory for cpu? A short simulation:

> library(RAppArmor)
> rlimit_as(1e9)
$hardlim
[1] 1e+09

$softlim
[1] 1e+09
