Sage install aborts: error building ppl

[Darij Grinberg]

Hi,

trying to install sage-5.11beta3 on a Ubuntu virtualbox inside a
Windows 7 host (64bit).

Here is what goes wrong:
https://dl.dropboxusercontent.com/u/83265276/ppl-1.1pre9.p0.log

The main error seems to be
"virtual memory exhausted: Cannot allocate memory"

I don't know enough about virtual machines to ensure that this is
really a VM bug, and even if it is, it is IMHO a Sage issue due to
virtual machines being an environment Sage absolutely has to run in.

Is there a way to skip a particular package when installing sage?

Thanks a lot,
Darij

How much memory (ram and swap) does your VM have?

Hi Volker,

Good point -- looking at the virtualbox settings, I see I deceived it about having 6 cores (the machine has 8, but the VM is allowed only 1). It compiles well now without that parameter.

Thanks for the good question! What RAM, CPU, etc. settings would you recommend for a virtual machine running sage?

  Best regards,
  Darij

Thanks -- though I'd have preferred more about the number of CPUs (I
still don't know whether anything in Sage is parallelized).

Parallel building is covered here:

The more you do in parallel, the more ram you need obviously.
