 Posted: Wed Sep 20, 2017 10:35 pm Post subject: Can I directly emerge an ebuild file? |
 |
|
Here's the setup. I want to use gpp, a preprocessor. But alas, there is no app-text/gpp in the main portage tree ::gentoo. However I did find it here: http://gpo.zugaina.org/app-text/gpp
The problem is that I don't have the slightest idea if it is a good move to hitch myself up to a strange repository. But they do have a gpp ebuild file. On the other hand man emerge says not to emerge ebuild files directly.
Is this really the case? Could I just download the gpp ebuild file and toss it into | Code: | | /usr/portage/app-text |
, and try to emerge it? Or would that really blow my system up?
Are there any other ways to deal with the "emerge the odd-lot package" issue, other than running the make file or attaching oneself to another repository?
Thanks |

I have not reviewed that ebuild, but as a general comment:
If you trust that one ebuild, you could create a personal overlay, populate it with just that ebuild and supporting files, then emerge from there. You should not modify under /usr/portage because those modifications will be lost on next sync. |

Makes sense. If somebody can have a personal trainer or a personal astrologer, then why not a personal overlay?
Maybe someone can put gpp into the main package repo. It's not a critical utility, but it has its place. |

You can tell to become a proxy maintainer for this package

JustAnother,
Ebuilds don't get much simpler.
| Code: | # Copyright 1999-2017 Gentoo Foundation

EAPI=6
DESCRIPTION="a general-purpose preprocessor with customizable syntax"
HOMEPAGE="http://en.nothingisreal.com/wiki/GPP"

Follow the handbook to make yourself a personal overlay.

It wouldn't blow your system up, portage would likely just abort with an error. One of the drawbacks of ebuilds is that unlike (S)RPM or DEB packages they aren't self-contained packages. To have a working package you also need several support files in a specific directory structure, which makes transferring individual packages somewhat tricky.
Interestingly enough RPM and DEB based distros have also moved to a repository-centric approach in the last years and made it more difficult to handle individual packages. |

I'm certainly willing to be a proxy maintainer, but I want to learn this portage system better before I jump on that. In the mean time I hope it is ok if I ask a few more questions. I'm trying to get my xfce work flow tweaked.
Thanks |
