Bug 448790 – sys-fs/lvm2 - Please don't depend on udev when USE="+static -udev". (was: static flag requires +udev)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description grey dot 2012-12-27 07:56:10 UTC]

Error occurs if static flag is enabled and udev flag is not.

Reproducible: Always

Steps to Reproduce:
1. USE="static -udev" emerge lvm2
Actual Results:  
The following USE changes are necessary to proceed:
#required by sys-fs/lvm2-2.02.97-r1[static], required by @selected, required by @world (argument)
>=virtual/udev-196 static-libs


Expected Results:  
lvm2 merged

What error? Attach the full build.log to this bug, thanks.

The description could have been more clear.

There is no build log, the error is under "Actual Results":

He has USE="+static -udev" set thus he doesn't want udev, yet emerge proposes an USE change that suggests it would add udev; he wants to emerge lvm2 without emerging udev. This only happens with USE="+static", since only then udev is introduced as a dependency.

To solve this unwanted dependency problem, he proposes a patch that would make lvm2 not emerge udev when USE="-udev" (regardless of how the static USE flag is set).

Yeah, thanks for clarification. I just wanted to write the same.
