Hi,

Another test build. All latest cvs commits are available in this one. Many bug fixes.
I still don't have an explanation for the crashes people experience. My only guess would be an incompatible Python version (prior to version 2.3).

You can find the latest builds here.

With regards,
Michel

well, I am running older python version... I haven't upgraded it because I am not sure what would happen... lot of tools in Fedora rely on python,.. and I am a bit afraid what would happen if I just go and download new python.

is 2.3 backwards compatible to 2.2 ?
if not, will 2.3 overwrite 2.2 upon istallation?
if I install python 2.3, can I still run old blender versions too?

these are the things I worry.. I need to work with my machine, it's not just testing ground, so I need to be careful

and finally, why 2.2 doesn't work with blender anymore?

Segmentation fault on linux mandrake 10 (blender static)

The same on slackware 9.0 : Segmentation fault

I tried to build one myself, but I haven't posted it, because as soon as I start to play sg with the game engine I get a segmentation fault. Other than that everything works fine. (Debian)

segmentation fault in Mandrake 9.2

Michel · Post by **Michel** » Fri Apr 16, 2004 1:48 pm

Hi,

thank you all for all the response on the segfaults. Unfortunately with no additional information, I can't fix any problem.
I have to make the following assumptions:
- The segfault occurs when starting blender.
- You have Python 2.3 installed

Please, provide a little more information.

By the way: Python 2.3 is not binary compatible with Python 2.2. Blender links in Python 2.3 support. This means modules compiled for Python 2.2 will not work. Scripts are supposed to be compatible within versions.
We were expecting the Python version problems. In the past there was a group who had trouble starting blender because they had Python 2.3 installed, now there will be a group who will have trouble starting blender because they have Python 2.2 installed. This is a problem that is worked on. The goal is to have this fixed before the Blender 2.33 release, but it all depends on the amount of time we have available.

With regards,
Michel

OK, you are right;

MDK 9.2;
Python 2.3 after deinstall 2.2;
segmentation at blender's start

Hello Michel

Mandrake 10 Comunity ships with Python 2.3.3
And you're wright the seg fault is at start up

Thank you for the effort
Bye

Hello,

The same as OTO for me ..

"Mandrake 10 Comunity ships with Python 2.3.3
And you're wright the seg fault is at start up "

And, on my Slakware 9.0 , Blender "seg fault" at start up to. ( i have Python 2.2 on this system).

But there's something i don't understand...
Blender should start even if you don't have python on your machine ?
Am i wrong ?
So, what is the problem if i have py 2.2 or 2.3 ?

Hello MIchel,

Iv'e tried to run blender with xxgdb under MDK 10.0, and here's the output message:

Using python 2.2.3. If you provide a debug build I can try to find out what exactly what goes wrong.

As Michel_ told in the beginning of the thread, you'll be needing Python 2.3
