Hi all. I have a strange situation and I'm wondering if anyone can help |
2 |
me understand it or give me tips on how to better understand it. |
3 |
|
4 |
I'm using Portage (2.0.49) to manage a set of locally-constructed |
5 |
ebuilds; these are not in the Gentoo system. |
6 |
|
7 |
I'm installing them through a "collection" ebuild, which contains |
8 |
nothing but a DEPENDS line, say collection-1.0.ebuild: |
9 |
|
10 |
DEPENDS=" ~category/foo-1.0 ~category/bar-1.0 ~category/baz-1.0 " |
11 |
|
12 |
In my packages file I say: |
13 |
|
14 |
* ~category/collection-1.0 |
15 |
|
16 |
|
17 |
Also the bar-1.0 and baz-1.0 packages depend on foo and they both say |
18 |
so, like this: |
19 |
|
20 |
DEPENDS=" category/foo " |
21 |
|
22 |
|
23 |
Now, I also have a foo-1.1, bar-1.1, and baz-1.1. The bar-1.1 and baz-1.1 |
24 |
packages depend on foo-1.1 and they both say so, like this: |
25 |
|
26 |
DEPENDS=" ~category/foo-1.1 " |
27 |
|
28 |
However, I want to install the older 1.0 versions right now, not the |
29 |
newer ones. |
30 |
|
31 |
|
32 |
Now if none of these packages are installed and I run "emerge system", |
33 |
something very bizarre happens: emerge _FIRST_ installs the latest |
34 |
category/foo-1.1 package, then it tries to build the other packages, |
35 |
which fail because they won't work with newer versions of foo! |
36 |
|
37 |
Then, if I run "emerge -p system" I see that emerge will, later on, |
38 |
replace the foo-1.1 it just installed with foo-1.0. |
39 |
|
40 |
|
41 |
Doesn't Portage have enough smarts to realize that if the collection |
42 |
package depends on a specific version and other packages depend on any |
43 |
version, that it should just install the specific version to satisfy the |
44 |
dependency relationship? |
45 |
|
46 |
If not, this is very bad! How can I work with this? Surely I don't |
47 |
have to go back to every old version and update all their DEPENDS lines |
48 |
every time I come out with a new package which is not backward |
49 |
compatible? |
50 |
|
51 |
|
52 |
And, is there any command I can run or option I can use to get a more |
53 |
detailed description of exactly how emerge is resolving dependency |
54 |
relationships? |
55 |
|
56 |
|
57 |
Thanks! |
