 |
|
Strictly speaking it doesn't - but in this situation it's very inconvenient, and probably not limited to Java development either.
I'll explain:
I'm a Java developer, and usually have a few different versions of the JDK installed. Not a very unusual situation on a development station.
For example, at the moment I have Blackdown's JDK 1.3, IBM's 1.1.8, IBM's 1.3.1, Sun's 1.3.1_03 and Sun's 1.4.0 installed. (And Sun's J2EE 1.3.1 as well)
Now, when I do a "emerge clean world", it tries to uninstall Sun's 1.3.1_03. Although 1.4.0 supersedes 1.3.1_03, it doesn't replace it, and portage shouldn't try to uninstall it.
Interestingly, it doesn't do this for some other ebuilds - still have to work out if that's by design, or a bug in portage.
Is there something wrong with the Sun-jdk ebuilds, or is this a more general problem in portage? |

When you check your /var/cache/edb/world file, does it just list "dev-java/sun-jdk"? If so, you're describing the expected behavior. clean is assumed.
What you *want* it to say is
"=dev-java/sun-jdk-1.4.0-r2"
"=dev-java/sun-jdk-1.3.1.2"
...
which pins the version numbers.
This is detailed in the portage manual:
http://www.gentoo.org/doc/portage-manual.html
Look for the section "World Update", or "code listing 19".
I haven't tried it, but I suspect that you might be able to use >= and < to pin "the most recent 1.3.x", or "the highest revision of 1.3.1".
Whatever you find please suggest an addition to the manual, or to the requested features list. |

Unfortunately, this doesn't work. Even if I pin both versions, clean wants to unmerge the 'older' 1.3.1.03 jdk. - I suppose because portage considers them to be versions of the same package - generally true, just not in this case.
For the same reason I don't think you can specify both "the most recent version of 1.3.1" and "the most recent version of "1.4.0" - at least, I can't get it to work  |

Huh. That's odd.
I'd expect the same behavior to be mirrored in the X11-libs/qt libraries, and it's not. I've got 2.3.2 and 3.0.4 running side by side without any trouble.
In fact, portage has reported as many as 5-6 different versions of the same package for me (libpng, for instance).
I wonder if there's something unique to the sun-jdk ebuilds, or to sun java itself?
I'm trying this myself. Let you know if I get things working. |

Heh! Exactly! I have several duplicate libraries (libpng, qt, kdlibs, ...) and they seem to live alongside each other quite happily...
I'd be interested in any extra info you might find... |

last two lines in my world file are
=dev-java/sun-jdk-1.3.1.03
=dev-java/sun-jdk-1.4.0-r2
If I unmerge sun-jdk, they both come out. If I merge one, then the other, they both stay. (even with "clean")
Pinning at >= doesn't work, nor does specifying the .ebuild, nor does specifying partial version numbers.
I did see some spooky behavior when I had only one installed and had added both to the world file -- I tried
emerge update clean world
and emerge knew to install the other.
Note I'm running portage 1.9.10, so that may make a difference... |

Yes - this works. (Now running portage 1.9.10 too)
Actually, I did some reading in the documentation (You did WHAT! Are you sick or something ), and I think this is what the "SLOT" system is in portage for. So the 1.3.1 and 1.4.0 jdks should be assigned slots, and all would work as expected... I think  |
