Try also running 32 bit app. System is not slower or anything else wrong happens. If You drop 32-bit support You cannot use WINE and load PE32 apps (aka Win32). --=20 Mateusz Mierzwi=F1ski Bluebox Software http://www.blueboxsoft.pl/mateusz-mierzwinski --0015174c37f889a2bd0496eff1c6 Content-Type: text/html; charset=ISO-8859-2 Content-Transfer-Encoding: quoted-printable

What are some things that I should watch for and enable that isn't so obvious for someone new to 64 bit?

=A0 =A0
The first thing to decide is whether or not you want a pure 64-bit
system or a 64-bit system that keeps 32-bit capability.

I am a purist. =A0I left 32-bit programs in the dust a long time ago.
But as a consequence there are some things that I will miss because
they are available in 32-bit packages only. =A0An example would be
Acroread, the PDF viewer, from Adobe. =A0Without Acroread, you will
only view pdf files through the 64-bit xpdf. =A0The Intel C++
compiler is another example. =A0In fact, most commercial software
that bothers to release a Linux version will do so in 32-bit
format only.

So if you need to make use of those offerings, you'll need
to keep 32-bit compatibility.

My own view is that these software developers are way behind
the times and should have long ago made their products in
a 64-bit form. =A0It's not that difficult to do.

Whatever the choice, pure 64-bit or 64/32, Gentoo makes it
easy.

Now I have a question. =A0How do I tell Gentoo to make it pure 64 or a mix = of 32 and 64? =A0I have read about this but I don't think I have actual= ly seen where it is set. =A0Is it a profile selection, USE flag or somethin= g else?

If I decide on one then want to switch to the other, does that require a re= install or just a change in settings and a recompile of world?

Since I use KDE, I always use Okular to view pdf files. =A0I assume KDE is = 64 bit ready.

Thanks.

Dale

:-) =A0:-)


You can set it in KERNEL by disabling 32 bit = application support and recompiling GLIBC and GCC without MULTILIB ;). Try = also running 32 bit app. System is not slower or anything else wrong happen= s. If You drop 32-bit support You cannot use WINE and load PE32 apps (aka W= in32).
