Hi all,
Hi there!
I run R with Shiny on a virtual server (Ubuntu 12.04). Since the last
version, I cannot install/compile RcppEigen any more, with the
following error message:
[...]
Obviously, I cannot increase physical RAM.
Any ideas how to proceed from here?
Here's an idea (disclaimer: this may be crazy... but it might just
work): Compile your binaries on another box, e.g., a VM (like VirtualBox
or VMware).
You can get the image corresponding to the same OS version you're going
to need (so as to avoid linking with different/incompatible sys libs),
i.e., "Ubuntu 12.04 Precise Pangolin" from OSBoxes:

Note: Remember to use -march=<cpu_of_your_deployment_target>, otherwise
you may end up with suboptimal (or even unusable) binary.
Here's the list:

Naturally, you definitely want to enable optimization (like
vectorization) that matches your deployment target:

Good luck!
Best,
