Posted: Mon May 26, 2008 4:22 am Post subject: [Resolved]overlay中有个同名的ebuild, emerge时怎么决定用哪个 |
|
|
比如我的
$PORTDIR/app-misc/xxx/xxx-1.0.0.ebuild
$PORTDIR_OVERLAY/app-misc/xxx/xxx-1.0.0.ebuild
假设这两个ebuild完全一样,一模一样
当我
emerge xxx的时候,emerge用的是哪一个ebuild呢?我又如何能指定emerge用某一个ebuild呢?
这个问题,官方没有文档说明吗?

肯定都没有屏蔽
你说的最新,是指xxx-1.0.0.ebuild这个文件的时间最新吗?emerge 就是看文件时间决定的吗?
哪有这方面的说明吗
谢谢 |

如果想知道emerge用那一個ebuild,用 Code: | emerge -av <package name> | overlay的會有[x]在尾部.
例:
顯示 Code: | These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] x11-wm/compiz-9999 USE="dbus fuse gnome gtk svg xcb -kde -kde4" 0 kB [1]
Total: 1 package (1 reinstall), Size of downloads: 0 kB
Portage tree and overlays:
[0] /usr/portage
[1] /usr/portage/local/layman/desktop-effects
Would you like to merge these packages? [Yes/No] |

Oh yeah, 这个我在你给我的那个网页里也看到了。现在我能清楚emerge xxx的时候用的是哪个了。
那个网页里是这样说的
Portage automatically searches your main Portage tree (in /usr/portage), and all of the overlays that you've installed, and picks the latest version of the package that it can find.
所以这里又出现了一个新问题:
我刚才说
$PORTDIR/app-misc/xxx/xxx-1.0.0.ebuild
$PORTDIR_OVERLAY/app-misc/xxx/xxx-1.0.0.ebuild
这两个ebuild是完全一样的
那么emerge是根据什么认为哪个ebuild是lastest version呢,不可能是根据文件名里的版本号吧,因为它们都一样。
也好像不是根据这两个ebuild的文件时间,因为我分别touch了两个ebuild,但emerge总是选择了固定的那一个,没有因为文件时间的改变而改变选择。。。

我不曉得別人是怎麼使用不同的overlay,但我是這麼選用不同的overlay。
借用你的例子說明一下:
Code: | These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] x11-wm/compiz-9999 USE="dbus fuse gnome gtk svg xcb -kde -kde4" 0 kB [1]
Total: 1 package (1 reinstall), Size of downloads: 0 kB
Portage tree and overlays:
[0] /usr/portage
[1] /usr/portage/local/layman/desktop-effects
Would you like to merge these packages? [Yes/No] |
1.選用[0] /usr/portage
Code: | # PORTDIR_OVERLAY="/usr/portage" emerge -av compiz |
2.選用[1] /usr/portage/local/layman/desktop-effects
Code: | # PORTDIR_OVERLAY="/usr/portage/local/layman/desktop-effects" emerge -av compiz |
這樣你就可以隨意切換使用ebuild了,用-av options就可以看出使用的是哪個overlay,只是這個方式麻煩一點,需要多打一點字。 |

嗯,多谢。
确实是这样的
我google到了这样文字证明了你的说法
Code: |
當要安裝這些套件時,系統中因為 overlay 的關係會有不只一種版本可以選擇,那這時 Portage 會選擇安裝哪個 repository 提供的套件呢?原則上,官方的 repository 也就是 official Portage tree 中的套件優先權最低,只要 overlay 中有提供版號相同的套件,那麼 overlay 的套件就會被 Portage 選來安裝。另外,如果有兩個以上的 overlays 提供同樣的套件,版號也相同,那麼最後一個被 included 進來的 overlay 則會取得最高的優先權,例如在 /etc/make.conf 中:
PORTDIR_OVERLAY="
/usr/portage/local/sunrise
/usr/local/portage
"
則 local overlay 中的套件優先權會高於 sunrise 的套件,這在想要控制要裝哪個 overlay 的軟體的時候是個有用的技巧。

非常感谢你的帮助。
经验值又长了一成 |
