[gentoo-user] random mouse movements + kdebase 3.5.9-r3 + qt-4.3.3 + gcc-4.3.2 problems

[Francisco Ares]

Hi, guys.  Happy new year!

I'm facing some problems.  It all began with some weird random mouse
movements and clicks once in a while, and also sometimes the graphical
interface locks up so that I cannot start nor close any program, even kde
itself.  I have to turn off the computer and turn it on again (resembles
another operating system, doesn't it? - but all the rest of the system still
works ok including ACPI power button, so I can get a clean reboot) and then
I had the idea of re-emerging several packages.

And now I'm having trouble while re-building kde-base/kdebase-3.5.9-r3,
kde-base/kdelibs-3.5.9-r4 and x11-libs/qt-4.3.3 - none of them compiles
without errors.

I'm using a "~x86" gcc ( sys-devel/gcc-4.3.2-r2 ) so that I may use the
"-march=core2" CFLAG and just emerged and installed a 2.6.27-r7 kernel.
Also I've re-emerged several qt and kde dependencies, including Xorg - as
long as several of its dependencies, too - and a long list of libraries, and
all went ok.

For Qt, the errors keep pointing test phases, which are not enabled here,
messages like theese:

MySQL (thread-unsafe) disabled.
MySQL support cannot be enabled due to functionality tests!
 Turn on verbose messaging (-v) to ./configure to see the final report.
 If you believe this message is in error you may use the continue
 switch (-continue) to ./configure to continue.
 *
 * ERROR: x11-libs/qt-4.3.3 failed.

Then I have masked MySQL, and then another USE flag points out the same kind
of error.

For kdebase, it points out a compilation error, as it seems, against a
kernel header, like this:

In file included from handler.h:13,
                 from kdesud.cpp:74:
secure.h: At global scope:
secure.h:19: error: redefinition of 'struct ucred'
/usr/include/bits/socket.h:321: error: previous definition of 'struct ucred'
make[3]: ** [kdesud.o] Erro 1
In file included from secure.cpp:23:
secure.h:19: error: redefinition of 'struct ucred'
/usr/include/bits/socket.h:321: error: previous definition of 'struct ucred'

But kdelibs re-emerged like a charm...

Any ideas?

Thanks in advance
Francisco
