Hello

i have amd64, but i have several binary applications compiled for x86
(32bit). I need to compile some dependant libraries for x86.
How can i do it using emerge ?

Thanx

Have you installed the following ebuilds?

emul-linux-ppc-glibc
emul-linux-x86-baselibs
emul-linux-x86-compat
emul-linux-x86-gtklibs
emul-linux-x86-java
emul-linux-x86-medialibs
emul-linux-x86-qtlibs
emul-linux-x86-sdl
emul-linux-x86-soundlibs
emul-linux-x86-xlibs

if you still need other packages, you will need to install crosdev, build
a x86 compiler and use it to build packages, you will need to modify
those, as you want to install them under the /emul/linux/x86, but in the
gentoo wiki there is a bit information how to build packages for other
arches, don't have the link, but think you can find it.

You shouldn't. I also have gentoo built for amd64, and it has 32 bit
compatibility libraries and runs 32 bit s/w with no problem.

The excellent Gentoo AMD64 installation manual covers both the use
of /multilib/ - which is the default set-up in Gentoo - and of using a
dedicated 32-bit /chroot'ed/ environment.

I suggest that the OP would take a peak there... ;-)

i found some info about multilib on:
http://www.gentoo.org/doc/en/handboo...?part=1&chap=6
and in the FAQ:
http://www.gentoo.org/proj/en/base/amd64/

but it's far from solving my problem. As i understeand multilib profile
is default when using amd64 stage3:
# ls -FGg /etc/make.profile
lrwxrwxrwx 1 50 Nov 17 06:08 /etc/make.profile ->
.../usr/portage/profiles/default-linux/amd64/2006.1/

The problem is:
How to emerge specific library for x86 archtecture ?
(they are emerged for x86_64 by default).
Maybe it's possible to emerge specific library for both x86 and x86_64 ?

Thanx

<Gentoo-specific n00b advice>

Out of my league here as I'm not running Gentoo myself yet at this stage,
but I would presume that the correct libraries would be pulled in
by /emerge'ing/ a specific 32-bit application.

That's the idea. Perhaps you could check your /package.keywords/ file?

no - they are not. Opera and vmware-workstations are examples.
They are 32bit binaries, emerge does not recognize it,
install that binaries but there are only 64bit libraries for them

for what ? could you clarify ?

Thanx

You emerge on of these:

emul-linux-ppc-glibc
emul-linux-x86-baselibs
emul-linux-x86-compat
emul-linux-x86-gtklibs
emul-linux-x86-java
emul-linux-x86-medialibs
emul-linux-x86-qtlibs
emul-linux-x86-sdl
emul-linux-x86-soundlibs
emul-linux-x86-xlibs

they are prebuilt packages, you get the libs that is most commonly used in x86
binaries which you can't get as x86_64 binary, as example Opera, flash and so on.

If you install crossdev, build an x86 gcc environment, modify ebuild to
install in the /emul/linux/x86 three, you should be able to install to install
two versions of the same library, just see to that the ebuilds has different
names as you don't want slotting here.


If you feel that the 32bit programs are all to important for you, then use a
32bit kernel with 32bit programs/libs only.

Opera works fine, just install the emul-libs that I have nagged about in two
posts in this thread now.

His idea is that you use x86 as keyword on packages

--- package.keywords ---
media-libs/megalib x86
--- eof ---

and then do: emerge media-libs/megalib

He thinks that this would build a x86 version of the media-libs/megalib, but
the keywords won't change what your gcc builds, so it won't work.
Note, there isn't any megalib ebuild.

Hi all,

if I'm not much mistaken, there may be a problem with your profile, too.
With 2006.1 you should either use the 2006.1/desktop/ or the
2006.1/server profile.

Correct me, if I'm wrong ;-)
