Warning about 64-bits Blender

I posted a thread over at ubuntuforums.

Suffice it to say, don't use it.

I was actually going to write a step-by-step tutorial for getting indigo + blendigo working in Feisty Fawn (the just released version of Ubuntu), and then I saw the console output (while trying to troubleshoot the blendigo script) telling me of this.

oh, I'm sad cause I want to install ubuntu 7.04 64bit version and move from winXP
would be better to install i386 version of ubuntu in this case?

[joegiampaoli]

I run ubuntu i386 and up to date I have not had any problems with indigo, it runs very well in ubuntu. I used to be a big XP user, now I have not used XP for almost over 6 months.

So I say Go Ahead!

You could just install the 32bit version of blender in the 64bit OS, couldn't you?

[joegiampaoli]

blender in 64 bit linux is still going to run in 32 bit mode because there is still no 64bit version of linux, I don't use 64 at all, compiling even the easiest things sometimes is a hassle because of package dependencies. Best thing to do is just go for 32bit, I don't even want to think about the drivers and such, I tested SuSE Linux in 64 bit about a year ago and it was a nightmare, and believe it or not it was slower.

rubbish.

also, 64bit linux has come on a long way. it works fine.
(caveat: so long as you're using up to date and well supported hardware - intel/nvidia chipsets - ati/intel/nvidia gfx etc)

especially ubuntu - it's so easy to install and maintain.

as for blender, yes you should install the 32bit version, regardless of whether the OS itself is 32 or 64 bit. the 32bit blender will run just fine on 64bit linux.

Nonsense.

I'm running the 64-bit version.

Drivers are less of a problem then say 64-bit Windows (!), because people can recompile drivers they have the source for already.

Not so in Windows. Good luck trying to get old stuff working, or webcams from little-known companies, etc.

About moving from XP:
I installed XP in a virtual machine (KVM works great - it's fullspeed basically, if your processor supports virtualization) to take care of things like photoshop.

Most everything else will run in WINE; yeah, even games.

[joegiampaoli]

What I meant to say was that there is still no 64 bit version of blender, a wrong play in words (I said linux, of course there is 64 bit linux), and I really don't see the use of working with a 64 bit OS when all the darn software still runs in 32 bit mode( I think only open office and other small packages are already compiled into 64 bit mode, but I don't see the great need of working with office appz in 64 bits), 32 bits software will just plainly run in 32 bit mode no matter if your OS is 32, 64, or even 128 bit...

The only thing that would be worth running in 64 bit mode would be 3D application software (like blender), since there isn't such, I just advise to stick to a 32 bit OS to make things a little easier for you, specially if you download third party software that asks you to compile on your own.

[zsouthboy]

Joe, all of the software distributed with a particular linux distribution (for example, Ubuntu x64) *IS* 64-bit.

Seriously. You compile the application against 64-bit libraries.

Blender is most definitely compilable as 64-bit -> this is the problem I point out in my original post.

Click "Render" in 32-bit Blender (you can have both installed), and it'll take LONGER to render than in 64-bit Blender.

I disagree about "worth" of running 64-bit software, also. Everything is snappier if the underlying OS is 64-bit -> you've got DOUBLE the registers for compilers to take advantage of, in a register-starved ISA (x86).

EDIT:
Lemme point out that I recommend sticking to 32-bit for most users, right now.

excuse me!

where is the link for downloading indigo for linux?

thanks

[dougal2]

there isn't one qwsade. you have to run the windows version under the WINE emulator.

[zsouthboy]

qwsade: Install WINE using your distributions software repository - or, compile from source, if needed.

Indigo will complain about two missing DLL files when you attempt to run it under WINE - simply google for both of them, download and copy into the main indigo directory. It works great.

[joegiampaoli]

qwsade
To install wine:
If you have ubuntu or another debian distribution linux run:

Code: Select all

sudo apt-get install wine

(I just checked the website download area and saw you can add repos for latest wine into your etc/apt/sources.list file)

If your linux is a RPM based distribution then you have to download the RPM directly from the wine website, they sure have almost all major distros there:

http://www.winehq.com/site/download/

To run indigo with wine first cd to your indigo directory then do:

Code: Select all

wine indigo "your_scene.igs"

I like to run at lower priority because I am always working on other things while it processes so I do:

Code: Select all

nice -19 wine "my_scene.igs"

If you have any more questions just ask.

Good Luck!

Blender is from now on safe to build in 64 bits environment, so get CVS and compile

[joegiampaoli]

Ok, that sounds nice, I will probably upgrade to latest ubuntu soon so I'll might go 64 and see what happens....
