[Maemo 5] Regarding Blender 3D - Page 5 - maemo.org

I have them enabled all the time but still cannot install libopenal1. Do you have a .deb package of that?

The command to run the blender should look like: "exec [path to blender] -correct? When I do this, xterm closes instantly...like a crash or sth. What am I doing wrong?

Cheers,
Ralph

you don't need the "exec" to run it. if you extracted it in /opt then run "/opt/blender-armel-n900/blender".
enclosed you will find the deb package that i used.

i agree with Qole that this wrapper will be useful more generally, but i'm still hoping for Blender on my phone.

thank you for the hard work.

Yes, its me again :P Thanks for the .deb file, but I cannot install it successfully - neither in app manager nor through x terminal. In app manager I get something like- cannot install libopenal1 whereas in x terminal the installation fails with sth like "dependancy problems prevent configuration of libopenal1".

And what is even more running "/opt/blender...." gets me "permission denied" message.

Well it seems that Im a creature with lots of issues...
Any clues?

Cheers,
Ralph

RafaLL92: no problem. the dependancy problem was expected. in xterminal, what are the dependancies openal requires?

these are the dependancies my openal1 needed. first I installed gcc-4.3-base_4.3.2-1.1_armel.deb by dpkg and then i installed libc6 and libgcc1 together ("dpkg -i libgcc1_4.3.2-1.1_armel.deb libc6_2.7-18lenny2_armel.deb")
libgcc1_4.3.2-1.1_armel.deb libc6_2.7-18lenny2_armel.deb downloaded from debian.org(search in google)

This is what I get, the info you need is there:

RafaLL92: did it work?

RafaLL92 | # 48 | 2010-03-11, 22:52 | Report

Well I think not unfortunately... it seems that I have messed up my system after installing libc6 etc.

In app manager it says that Maemo 5 is damaged and i have to use NSU to repair it, which means reflashing really. Im suffering from a constant notification box saying: "internal error. calendar app closed" even if im not trying to run calendar and even after rebooting.... It also means that my battery drains out quite quickly and I cannot access the calendar app (it closes as soon as I launch it).

What is even more, after installation of those .deb packages from debian.org my system time got reverted by 1 hour and my system no longer seems to recognize time zones at all. That is probably causing the calendar problem...

Well, im waiting fot the new system update for maemo. I hope it will get released soon, but a reflash is inevitable.

So I think I will wait until an end-user version of blender for maemo5 will get (if ever)ready and released before I start to mess with stuff I do not really understand

But big thanks for your help!

Cheers,
Ralph

i took a more hackish approach:

first i tried in easy debian - the libc dependency would've been a breeze, unfortunately the furthest i got was:

Code:

[user@deb-m5v3b: /opt/blender-armel-n900]./blender 
Xlib:  extension "GLX" missing on display ":0.0".
intern/ghost/intern/GHOST_WindowX11.cpp:190: X11 glxChooseVisual() failed for OpenGL, verify working openGL system!
Segmentation fault

this also happens when trying :1.0 for the LXDE, but that was even less probable to work.

putting aside the bad image of "--force-depends" (

), i then decided to try this sledgehammer-approach:

Code:

# apt-get install libgl1
# dpkg --force-depends -i libopenal1_1.4.272-2_armel.deb
# echo "/opt/blenderlibs" >> /etc/ld.so.conf
# ldconfig

libgl1 was the only missing dependency on my unit.
libopenal should be installed last, for it will upset apt-get (running "apt-get -f install" will remove libopenal1 again if you run into trouble)

and, lo and behold, it works!

it takes some time to load, it isn't actually useable yet (opening the file menu took a while...), and for some reason, pulseaudio went crazy and fought with blender over the cpu cycles... also, blender wouldn't quit gracefully, forcing me to kill it, but after that everything went calm again.

but it's nice to see what might be possible!

now, some source code (especially that openGLes wrapper) would be totally awesome

SubCore: From your mention of libgl1, the sledgehammer approach was done in Maemo.

I'm curious, now. I wonder if we could hack Maemo's libgl1 into Easy Debian to replace one of the libgl1-mesa-xxx packages and get HW acellerated OpenGL?

Probably not. But I wonder...
