This file is intended to be a brief introduction to the build |
This file (UPDATING) is intended to be a brief reference to recent |
process and a reference on what to do if something doesn't work. |
changes that might cause problems in the build process, and a guide for |
|
what to do if something doesn't work. |
|
|
|
For a more detailed description of the recommended way to build NetBSD |
|
using build.sh, see the BUILDING file. |
|
|
|
Note that much of the advice in this UPDATING file was written before |
|
build.sh existed. Nevertheless, the advice here may be useful for |
|
working around specific problems with build.sh. |
