Hello Rajiv, compiling without errors, but blender crash directly after i start it.
Error in console=
“ungueltiger Maschinenbefehl” in english
“invalid computer instruction”
opensuse 11/64
intel Q6006
Where i start deleting flags in user-config.py.
3dnow and frerun-cse-after-loop is ereased, but the same error.
Greets mib

ps. is it possible to expand this textfield or reduce textsize.
It is very hard to write in. :-)

Hi mib2berlin

Are you using opensuse?

I wrote these instructions for Ubuntu 8.10.

as you can see, it states in the flag statement “nocona” if you have another cpu, you need to replace it with that, for example if your cpu is Intel Core 2 quad Q6600, then you need to replace “nocona” with “athlon64″ in “CCFLAGS = ['-pipe', '-fPIC', '-march=nocona', '-ftracer', '-fomit-frame-pointer', '-ffast-math', '-m3dnow', '-msse', '-msse2', '-msse3', '-msse4', '-mmmx', '-funroll-loops','-frerun-cse-after-loop', '-frerun-loop-opt', '-fforce-addr', '-funsigned-char', '-fno-strict-aliasing']
CPPFLAGS = ['-DXP_UNIX']
CXXFLAGS = ['-pipe', '-fPIC', '-march=nocona', '-ftracer', '-fomit-frame-pointer', '-ffast-math', '-m3dnow', '-msse', '-msse2', '-msse3', '-msse4', '-mmmx', '-funroll-loops', '-frerun-cse-after-loop', '-frerun-loop-opt', '-fforce-addr', '-funsigned-char', '-fno-strict-aliasing']”

I hope that should solve your problem

Thank you for reply, change to athlon64 dosend matter, i change to CCFLAGS. CPPFLAGS do not work.
But i am a newbie with compiling, and i try to build a fast blender works also with YoFrankie. http://www.yofrankie.org/

Rajiv: OK, but you should also warn people:

DO NOT USE SUCH BLENDER BUILD FOR A PRODUCTION!!!

Such aggressive optimizations (-O3 with -ffast-math?!) lead into serious computing errors!

Hi Igor. Thanks for the warning, but there is nothing to worry with the present builds.
I personally haven’t seen any or encountered any problems and I am using it for Film and Video production.
The only drawback is that the size of the executables, once in ram it takes up almost twice the space compared to an un-optimized blender (that is a well 40mb extra).

I have used the optimized blender to run complex liquid simulations with SSS and Raytrace with AA and was pleased with the results.
It rendered almost 35 percent fast with no visible artifact, Infact I compared the result with the non-optimized official blender build and found no perceptible difference.

I did run into problems with 2,44 build, but with 2.6 and 2.8 builds, a 40 percent speed increase is worth the risk.
So if you can afford a slight increase in the size of the executables, I would recommend any one to go for it -ram is cheap these days.

But sure I should have added (try at your own risk) and yes these optimizations have no effect on external renderers… so if you encounter render glitches as I did on 2.44 build keep the official build handy.

Thanks for the warning

Rajiv

Ubuntu 8.10 here.  After running the first line “sudo apt-get build-dep blender” I get:

Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to find a source package for blender

any ideas?

HI Ben
try now and let me know if everything works.

I’m getting the exact same thing.  Is there something else I need to do before running the “sudo apt-get build-dep blender” line?

Hi Ben Strange! Everything works fine here, I did a fresh (temp) install and everything went fine.

check that you have all the default repository enables including Medibuntu

run$ sudo apt-get install ubuntustudio-graphics

-and let me know what it says?

I did that command, and it installed almost 200MB of additional things, and then required a reboot.  After the reboot, I re-ran the “sudo apt-get build-dep blender” command, and still got the same “Unable to find a source package for blender” as before.

Also, when I try to run Blender from console it says:
guessing ‘blender-bin’ == ‘/usr/bin/blender-bin’
Compiled with Python version 2.5.2.
Checking for installed Python… got it!
Segmentation fault

and my screen flashes quickly as if it was trying to open, and then nothing else happens.  Checking my processes after this, there is nothing named “blender” running in the background.

(Btw, running a downloaded copy of Blender seems to run OK… except when I try to choose “Hotkey and MouseAction reference” from the Help menu, it tells me “Python Script Error: Check console”. But I can’t check the console because I can’t figure out how to run the downloaded copy *from* the console, and Blender here in Ubuntu doesn’t give me a separate console window when you run it like it does in Windows…)

Ben, There are several reasons why Segmentation fault occurs, for example “when critical shared libs, config file or /dev/ entry missing. or drivers esp onboard graphic related ones can also create problem. I have also seen this with AMD-Ati GPU’s.”
The “Python Script Error” might be related to missing shared libs, config file or /dev/ entry’s

Kindly note that you can run blender in console mode by typing
./blender
or
./Blender/blender
or cd[ing] into the dir and simply running blender from there by typing blender -w

also note that the 810 release is still buggy. check that you have all the updates by typing$ sudo apt-get update and sudo apt-get upgrade

you may want to run$
sudo apt-get autoclean
followed by
sudo apt-get update
sudo apt-get dist-upgrade

If the downloaded copy of Blender runs OK, then I would recommend you to use it while Ubuntu irons out the bugs.
Usually the long term release (804) are rock solid followed by experimental release (810) and a Userfriendly release (904)

Nevertheless, If you decide to reinstall 810 I suggest you do a memory check as well as disk (CD) check when it gives you the option at boot.
Usually its faster to resolve the problem by having a quick clean re-install.

Before you do a re-install you can try creating a new User and logging into him
This will create a new home folder and re-fresh the directory list.

Thanks for all the info.

What would I need to do to make a ‘ultra fast Blender’ for Ubuntu 8.04 instead of 8.10?

Hi Ben, you just need to download and install a fresh copy of Ubuntu liveCD from their site.
Also I recommend using UbuntuStudio rather than Ubuntu.
you can download it from here: http://cdimage.ubuntu.com/ubuntustudio/releases/8.10/release/
or
http://cdimage.ubuntu.com/ubuntustudio/releases/8.04.1/release/

hope that helps :)

Thanks… But I know where to get it and how to install it.  :) I’ve gone back and forth between Ubuntu and UbuntuStudio in the past.

But anyways, I’m going to put 8.04 on another partition, and wanted to know what steps I’d have to take to “compile an ultra fast Blender-3D binary” … on 8.04 instead of 8.10.  Is it the same steps as above, or do I need to do something different?

Yes Ben, the steps are the same :)

Hello Ravij, can i do this on Linux mint? I’m new to compiling so if there should be any changes to the process please explain it a bit.

thank you

Certainly Freyd (atleast as far as the last one which If I am not wrong is ‘Elyssa’)
Please see that that the new one (RC1) has problem with the new python (scons) though unconfirmed! cant say for sure.

Hello Rajii how do I optamixe system specific blender builds for xubuntu

I also want a stable a fast and an ultra fast blender.
thankyou
Mike chang

Hi Mike

You have to do 3 things I suppose

For Stable use these:

CCFLAGS = ['-pipe','-fPIC','-march=native','-mtune=native','-msse','-msse2','-msse3','-mssse3','-mmmx','-mfpmath=sse','-funsigned-char','-fno-strict-aliasing']
CXXFLAGS = ['-pipe','-fPIC','-march=native','-mtune=native','-msse','-msse2','-msse3','-mssse3','-mmmx','-mfpmath=sse','-funsigned-char','-fno-strict-aliasing']
REL_CFLAGS = ['-O2','-fomit-frame-pointer','-funroll-loops']
REL_CCFLAGS = ['-O2','-fomit-frame-pointer','-funroll-loops']

For Fast use these:

CCFLAGS = ['-pipe','-fPIC','-march=native','-mtune=native','-msse','-msse2','-msse3','-mssse3','-mmmx','-mfpmath=sse','-funsigned-char','-fno-strict-aliasing']
CXXFLAGS = ['-pipe','-fPIC','-march=native','-mtune=native','-msse','-msse2','-msse3','-mssse3','-mmmx','-mfpmath=sse','-funsigned-char','-fno-strict-aliasing']
REL_CFLAGS = ['-O3','-fomit-frame-pointer','-funroll-loops']
REL_CCFLAGS = ['-O3','-fomit-frame-pointer','-funroll-loops']

for Ultra Fast use these:

CCFLAGS = ['-pipe','-fPIC','-march=native','-mtune=native','-ftracer','-fomit-frame-pointer','-ffast-math','-m3dnow','-msse','-msse2','-msse3','-mssse3','-mmmx','-funroll-loops','-frerun-cse-after-loop','-frerun-loop-opt','-fforce-addr','-funsigned-char','-fno-strict-aliasing']
CPPFLAGS = ['-DXP_UNIX']
CXXFLAGS = ['-pipe','-fPIC','-march=native','-mtune=native','-ftracer','-fomit-frame-pointer','-ffast-math','-m3dnow','-msse','-msse2','-msse3','-mssse3','-mmmx','-funroll-loops','-frerun-cse-after-loop','-frerun-loop-opt','-fforce-addr','-funsigned-char','-fno-strict-aliasing']

REL_CFLAGS = ['-O3','-fomit-frame-pointer','-funroll-loops']
REL_CCFLAGS = ['-O3','-fomit-frame-pointer','-funroll-loops']

If you are using a 64 buildadd these below

BF_OPENAL_LIB = ‘openal alut’
#BF_OPENAL_LIBPATH = ‘${BF_OPENAL}/lib64′
WITH_BF_OPENMP = ‘true’
WITH_BF_OGG = ‘true’
WITH_BF_INTERNATIONAL = ‘true’
WITH_BF_ELBEEM = ‘true’
WITH_BF_VERSE = ‘true’
WITH_BF_YAFRAY = ‘true’
WITH_BF_GAMEENGINE=’true’
WITH_BF_BULLET = ‘true’
WITH_BF_PLAYER = ‘true’
WITH_BF_ODE = ‘true’
WITH_BF_JPEG = ‘true’
WITH_BF_PNG = ‘true’
WITH_BF_OPENEXR = ‘true’
WITH_BF_FTGL = ‘true’
WITH_BF_FMOD = ‘true’
WITH_BF_FFMPEG = ‘true’
WITH_BF_QUICKTIME = ‘false’
WITH_BF_OPENAL = ‘true’
WITH_BF_SDL = ‘true’
WITH_BF_ICONV = ‘false’
WITH_BF_STATICOPENGL = ‘false’
BF_PYTHON_VERSION = ’2.5′
BF_DEBUG = ‘false’
BF_TWEAK_MODE = ‘false’

let me know how it went
also note as you asked for specific system centric builds, these builds may or may not work on systems other then those on which they are built.
also try experimenting with the various settings, they are explained in detail in the GCC manual.

For 2.5 ubuntu 910 do the following

install deps:

sudo apt-get install subversion scons g++ libx11-dev libgl1-mesa-dev libxi-dev zlib1g-dev libpng12-dev libglu1-mesa-dev build-essential libjpeg-dev libjpeg62-dev libfreetype6-dev libtiff4-dev libopenexr-dev libsdl1.2-dev libsdl-dev libopenal-dev python-dev python3.1-dev libfftw3-dev libsamplerate0-dev libjack-dev libavformat-dev libxvidcore4-dev libogg-dev libfaac-dev libfaad-dev libx264-dev libmp3lame-dev libvorbis-dev libtheora-dev libswscale-dev libavdevice-dev libalut-dev gettext yasm cmake openexr

and then:

svn checkout https://svn.blender.org/svnroot/bf-blender/trunk/blender

finally create these user-config.py:

BF_NUMJOBS = ’4′
WITH_BF_OPENMP = ‘true’
WITH_BF_SNDFILE = ‘true’
WITH_BF_OPENAL = ‘true’
WITH_BF_JACK = ‘true’
WITH_BF_SDL = ‘true’
WITH_BF_OPENEXR = ‘true’
WITH_BF_DDS = ‘true’
WITH_BF_JPEG = ‘true’
WITH_BF_PNG = ‘true’
WITH_BF_ZLIB = ‘true’
WITH_BF_BULLET = ‘true’
WITH_BF_OGG = ‘true’
WITH_BF_FFTW3 = ‘true’
WITH_BF_OPENJPEG = ‘true’
WITH_BF_REDCODE = ‘true’
WITH_BF_OPENGL = ‘true’
BF_OPENGL=’/usr/lib64′
BF_OPENGL_LIBPATH = ‘/usr/lib64′
BF_OPENGL_LIBPATH = ‘${BF_OPENGL}/usr/lib64′

If I may add to a great thread, there is great info from the Gentoo community about cflags:
http://en.gentoo-wiki.com/wiki/Safe_Cflags
Its worth noting, that sse4 is valid for opteron/k10 and Intel i7, and when used sse3 is ignored as all sse3 instructions are part of sse4 anyhow. Its also important to know what version of gcc you have installed.
