I cannot untar kernel sources on my virtualbox VMs with <=256M either, |
| 81 |
and that goes back at least 18 months. tar just consumes too much |
| 82 |
memory. Your options: |
| 83 |
|
| 84 |
- untar somewhere else and copy the uncompressed sources over |
| 85 |
- get more memory |
| 86 |
|
| 87 |
when you build the kernel, you will find the same issue. gcc is going to |
| 88 |
use much more ram than 256M to get the job done. |
| 89 |
|
| 90 |
Do keep in mind that you can probably get that VM to *run* in teeny |
| 91 |
amounts of memory - maybe even only 64M - but building a kernel is a |
| 92 |
hugely memory-intensive task |
