|
can some body give me some guides on portage overlay, I try to use others ebuild,but it does not work
I followed this
http://www.webos-internals.org/wiki/Building_a_cross_toolchain
but i get this when build
| Code: |
Calculating dependencies
* IMPORTANT: 1 news items need reading for repository 'gentoo'.
* Use eselect news to read news items.
* Missing digest for '/usr/local/portage/cross-arm-none-linux-gnueabi/linux-headers/linux-headers-2.6.23-r3.ebuild'
... done!
!!! All ebuilds that could satisfy "cross-arm-none-linux-gnueabi/linux-headers" have been masked.
!!! One of the following masked packages is required to complete your request:
- cross-arm-none-linux-gnueabi/linux-headers-2.6.23-r3::x-portage (masked by: corruption)
For more information, see the MASKED PACKAGES section in the emerge
man page or refer to the Gentoo Handbook.

i do not understand this
| Code: | * Missing digest for '/usr/local/portage/cross-arm-none-linux-gnueabi/linux-headers/linux-headers-2.6.23-r3.ebuild'
... done! |

is there some thing wrong with the ebuild?

You need to replicate the 'category/package/packagename-version.ebuild' structure in your overlay, then run 'ebuild category/package/packagename-version.ebuild manifest' and then you're ready to go - provided the .ebuild is valid and the ebuild's name adheres to the standards.

Depends what you need to change, and how much work that is. F.e., if you just need to change some paths in some file, you can use `sed` in an ebuild. If you want to apply an already provided patch, you could use epatch.
So for short, give more information and in the meantime, have a look at this: http://devmanual.gentoo.org/quickstart/index.html
