Bug 410365 – app-portage/gentoolkit - euse -i c++0x

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Denys Duchier 2012-03-31 16:05:06 UTC]

the new flag c++0x (e.g. used by qt packages) is not properly handled by euse.

global use flags (searching: c++0x)

but the flag is not actually active (none of the newly compiled qt packages has been built with it). (btw, I have no idea what M means: it's not documented).

The USE-flag is masked in the profile (can cause problems). You have to unmask it.

Assuming M means masked. I still don't understand the output of euse: why the +? why the E? why the G?

"man euse" should help.

dude, I have read the man page.  why does euse think that the flag is seen active by portage (+)?  why does it think that the flag is enabled in the environment (E)? it definitely isn't.    why does it think the flag is enabled in make.globals G)? it isn't.

This has been fixed in the following commit:

http://git.overlays.gentoo.org/gitweb/?p=proj/gentoolkit.git;a=commit;h=79135c7585402eadeb9e06cbf3138f0d191b15d9

The '+' characters in the useflag were causing problems with a regular expression in the code.

This was released with gentoolkit-0.3.0.6-r2
