 Posted: Wed Apr 16, 2003 3:23 am Post subject: managing portage tree and compiles from source |
 |
|
If I find a program source that happens not to have an ebuild, and I compile it to run on my Gentoo system, what happens if that package has an ebuild later on? Will portage start watching for upgraded versions if I do an emerge -u world?
Also, if I compile a program from source, not using an ebuild, how do I uninstall it? I've gotten used to the ease of "emerge unmerge".  |

If you installed the package with the same layout (FSH standard) structure as the ebuild uses, you can install over it.

Doing an update effectively does an install and if there's already an entry in the portage db, it is updated to the current version numer. In other words, the existing package should be overwritten with the 'updated' version from portage.

There is no easy way and it's very package dependant. You may have to hunt and peck for files all over the place and is not for the faint of heart.
You can cheat and give the package you install manually a prefix where it can be easily removed from. For example, you can put Apache in /opt/apache-x.xx so you know right where it is and how to easily remove it (rm -rf /opt/apache-x.xx) when it gets into portage. (Of course, Apache is already in portage - just an example).
Hope that helps. |

The path of least resistance (true laziness) could be to write your own ebuild. There is a template in /usr/portage/skel.ebuild. If you do you should keep it in /usr/local/portage/$GROUP/$PACKAGE/ and set | Code: | | PORT_OVERLAY="/usr/local/portage" |
in your make.conf. If you can install it, you can write an ebuild.

Well, laziness is one of the main reasons why I started using Gentoo. Much easier to use portage to update and install packages, so I don't have to expend effort with rpm dependency issues. 
I'll look into writing ebuilds, when I get a chance. |
