Multilib Issue

[tolvo]

Hello, 

 my doubt is for enable a multilib system (able to run wine, skype, ...) I just have install "emul-linux" packages?

[Oleg Vinichenko]

for skype as 32-bit application you need a multilib system, yes and yes until multilib convertion done, emul-* packages is a requirement.

Yeah, I know that a "obvious" question, but I think this "so easy" and I have little problems with found some information about multilib in gentoo/funtoo so I ask to kill my doubt. Thanks.

[Philipp Ludwig]

You can also setup a multilib system without the emul packages: http://wiki.gentoo.org/wiki/Multilib_System_without_emul-linux_Packages

 

I did this successfully with funtoo a few weeks ago, however, minecraft didn't work (because java can't handle the different 32 and 64 bit libraries the correct way). Everything else worked though, even Skype with apulse withpout pulseaudio.
