wpa_supplicant with USE="qt4" requires qt4 with USE="qt3" (that flag was added
in qt-4.2.1-r1) or patching it to be pure Qt4 app.

In qt-4.2.2, the Qt3Support libraries can be turned on/off with the qt3support
flag.  Adding a check for it to this ebuild is probably all that's needed.

As of today, this bug still exists for:

wpa_supplicant-0.5.6
qt-4.2.1

 (In reply to comment #1)

I was experiencing this issue and I found this bug.
I added qt3support USE flag per the above comment, to the x11-libs/qt and
recompiled both wpa_supplicant, x11-libs/qt fixed the issue.

Here is the versions I am using along with the associate USE flags used to
compile the software.
x11-libs/qt-4.2.2  USE="-accessibility cups -dbus -debug -doc -examples
-firebird gif -glib jpeg mng mysql nas -nis -odbc opengl -pch png -postgres
qt3support sqlite -sqlite3 xinerama zlib" INPUT_DEVICES="-wacom"
net-wireless/wpa_supplicant-0.5.6  USE="dbus -gsm madwifi -qt3 qt4 readline
ssl" 

Fixed, thanks

This check is broken, only qt-4.2.2+ has this flag...

wpa_supplicant-0.5.6.ebuild.diff

Fixed, thanks Jakub :)

*** Bug 165840 has been marked as a duplicate of this bug. ***

The check is broken with:
[ebuild   R   ] x11-libs/qt-4.2.2  USE="accessibility cups dbus gif jpeg mng
opengl png sqlite3 zlib -debug -doc -examples (-firebird) -glib -mysql -nas

The check is present in 0.5.7

The bug also exists in 0.5.4
backport?

Reopening as this still isn't fixed for all versions of wpa_supplicant

As a comparison, look at this, when I try to emerge umbrello:

emerge: there are no ebuilds built with USE flags to satisfy
"x11-libs/qt-core:4[qt3support,ssl]".
!!! One of the following packages is required to complete your request:
- x11-libs/qt-core-4.5.0 (Change USE: +qt3support)
(dependency required by "kde-base/umbrello-4.2.1" [ebuild])
(dependency required by "umbrello" [argument])

This looks a lot like something I'd expect for wpa_supplicant in this case,
they do some kde inherit stuff in the ebuild, maybe it's possible to do a a
similiar check for wpa_supplicant?

This problem can be fixed (I hope) by a patch I'm going to attach soon. The
patch, however, depends on that another bug (bug #264403) is fixed first (does
not apply if you use Qt 4.5.

Patch for improved dependency on qt3support

Improves the dependency checking on USE qt3support in x11-libs/qt-core or
x11-libs/qt. Simplifies the checking by using EAPI=1 features.

Hm, there may be two typos:
1. It should be [qt3support] instead of [qt3support=]
2. This USE flag checking is an EAPI2 feature, so the ebuild should require
EAPI=2

Further comments are welcome...

uberlord was retired long ago... this bug should be reassigned to mobile@g.o I
guess...
