 |
|
Ok ist getting math now.
I consider the flags in the USE parameter as a list.
Is this list merged with the list in /etc/profile/make.default,
while a "-flag" is considred to remove the member out of the list ?

Not sure I completely understand your question, but I believe the answer is yes.
If you have a USE variable string set as follows:
| Code: | | USE="java -gtk kde" |
Then portage will compile things with java support, without gtk support and with kde support.

well, i have been misunderstood.
example:
we have in /etc/make.profile/make.default the USE settings of:
aaa bbb ccc ddd eee ..... zzzzz = list (a)
and in /etc/make.conf
these USE settings of:
-ccc ddd -eee ... nnn = list(b)
so the merge of list (a,b) =
aaa bbb ddd fff ... nnn ... zzz
so my question is , does it behave like this or
is /etc/make.con taking proiority against /etc/make.profile/make.default
thus resulting only the use setting in make.conf taking effect regardless what is in .....

Actually, that document doesn't answer tebers' question. However, the man page for make.conf does. To quote:
| The man page for make.conf wrote: |
This file contains various variables that are used by
Portage. Portage will check the currently-defined envi-
ronment variables first for any settings. If no environ-
ment settings are found, Portage then checks
/etc/make.conf. If no setting is found in /etc/make.conf,
Portage checks /etc/make.profile/make.defaults. If no
setting is found there, the default setting is grabbed
from /etc/make.globals. Please note that all user set-
tings should be made in the environment or in
/etc/make.conf, which is intended to be customized by the
user.

Even on your worst day, your English is much better than my German.

i just want to be sertain about this. use list in Thorstons example:
| Quote: |
we have in /etc/make.profile/make.default the USE settings of:
aaa bbb ccc ddd eee ..... zzzzz = list (a)
and in /etc/make.conf
these USE settings of:
-ccc ddd -eee ... nnn = list(b)
|
the result would be:
right?
I was confused about this. It appears from the docs that this is the way.

I thought I understood but now I am confused too!
If you add a -optionX in /etc/make.conf to disable support for something in the defaults, why do you need to add optionY to enable another option?

Answer is because there are use variables that are not in make.defaults
So obvious I'm kicking myself |

| I understand that part pretty clearly (at least I think I do, I could be mistaken). Anyway, the part I don't understand is what to do if a package wants something you don't. For example, I had -kde -arts and something (freeamp I think) required arts. Well, I don't use KDE, so why should I have to have it? Just seems odd. From that standpoint, I don't get USE at all. The docs tell you to use -kde -arts at a minimum to disable KDE, yet other non-KDE programs fail to build. Is this just an ebuild issue? |

as I have looked now to the man-page I have come to this conclusion.
we get this
| Code: |
we have in /etc/make.profile/make.default the USE settings of:
aaa bbb ccc ddd eee ..... zzzzz = list (a)
and in /etc/make.conf
these USE settings of:
-ccc ddd -eee ... nnn = list(b)
|
the result will be
| Code: |
list(b)= -ccc ddd -eee ... nnn
|
means use not ccc and not eee but use ddd ... nnn
Therefore I would recommend copy all the flags from the /etc/make.profile/make.default to /etc/make.default and and negate all that you do not want with an "-"

| The freeamp ebuild script contains so that's why it's asking for it. Now why that is neccessary is a different question... |

USE variables have no effect on package requirements. Only suggestions. If something requires QT or arts or gtk or whatever in order to run properly, then emerge is going to install it regardless of what USE variables you have set.

Interesting... freeamp would not build until I remakred out my USE line. |

Could be a bug in the freeamp ebuild. That shouldn't have an effect on whether or not a package builds.
