Maybe there is some arch-specific configuring to do? I have no idea whether these limit parameters require tweaking...

Add a few gigabytes of swap, if you can. If that doesn't work, try running x86_64, if you don't.

You might need more than ~57MB of address space to run the compilation. -- Byron Clark
