linux-info.eclass: lacking sources, config checks and module building |

As part of the ongoing work in linux-info and cleaning up it's ebuild |
6 |
consumers, I have added a QA check to linux_chkconfig* functions. |
7 |
A lot of the tree has been cleaned up, but I still see new ebuilds being |
8 |
added that need the legacy mode. |
9 |
|
10 |
In one month, on January 10th, I plan to flip the switch between legacy |
11 |
and non-legacy mode, and default to the new style. |
12 |
|
13 |
If you want to use them directly in an ebuild, you MUST call one of the |
14 |
linux_config_*exists functions prior!. Otherwise the result of the |
15 |
linux_chkconfig* function is undefined in non-legacy mode. |
16 |
|
17 |
Legacy: |
18 |
- kernel sources must be present and .config must exist. |
19 |
|
20 |
Non-legacy: |
21 |
(available with I_KNOW_WHAT_I_AM_DOING=1 right now) |
22 |
- .config OR /proc/config.gz must exist if you want to check |
23 |
- any checks MUST be non-fatal, because the above files are not |
24 |
guaranteed to exist. |
25 |
|
26 |
If you are displaying a warning or an info block because of a specific |
27 |
return value from linux_chkconfig, you should consider if you want to |
28 |
display the warning/info if the state of the variable is unknown. |
29 |
I suggest that you DO display the warning, possibly with an additional |
30 |
line that the check was not performed. |
31 |
|
32 |
If you just use the CONFIG_CHECK and the ERROR_<CFG>, WARNING_<CFG> |
33 |
variables via check_extra_config, then the user is automatically |
34 |
provided with the following warning: |
35 |
==== |
36 |
* Unable to check for the following kernel config options due |
37 |
* to absence of any configured kernel sources or compiled |
38 |
* config: |
39 |
* - (option) |
40 |
... |
41 |
* You're on your own to make sure they are set if needed. |
