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. |

changed to indicate that our libc has ssp support built-in and |

The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been |
|
withdrawn. Use vidcvideo and pckbd instead. See the GENERIC |

kernel configuration for an example. X servers from the last |
|
few years should cope. |

MPACPI is no more. We always configure PCI interrupts using ACPI |
|
if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed |
|
to ACPI_SCANPCI. Thanks to work from fvdl. |
