Bug Report

Mario Alexandre Nobre Saleiro
Hi!

I have started to test OpenSCAD on Ubuntu 9.10 Karmic Koala with kernel
2.6.31-16-generic and I am having some problems with it. I installed it
using the instructions in the OpenSCAD manual and after a little problem
that was fixed by Clifford everything went ok.
After installing I tried the first example from the OpenSCAD manual and
the OpenSCAD just closed itself when I press F5 or click the Compile
option in the menu. However, if I click F6, it doesn't close and the
figure is shown. I have also noticed that when I choose OpenCSG under
the View menu after I press F6 the program closes itself too.

Regards,

Mário Saleiro

this is a problem with your OpenGL driver. could you please do the
following things:

1. find out what grafics hardware and which driver you are using. post that
information as reply. (the tool "glxinfo" should print out all relevant
information and much more)

2. run openscad from a terminal window. is there any output printed to the
terminal? if so - what is it?

3. run openscad using strace: just install 'strace' and the run it using
"strace -o output_file_name full_path_to_openscad_bin", let it crash by
pressing F5 and post the generated file. this files tend to be rather
huge. so maybe you could put it somewhere online (e.g. pastebin.com) and
just post the link?

4. run openscad in gdb and create a stack backtrace: just install 'gdb' and
run it using "gdb full_path_to_openscad_bin" and then type "run". Let it
crash by pressing F5 and then type "bt" on the gdb prompt. post the output.

OpenSCAD should work with all OpenGL 2.0 cards and hardware. It detects on
startup if your setup provides OpenGL 2.0 support and automatically
disables the advanced OpenGL stuff when there is no proper hardware/driver
support. It is possible that this features will never work with your
hardware. In this case a "bugfix" would only do better checking of the
needed GL support and result in properly disabling some features..

Hi,

I have made everything you said and the four files can be downloaded
from:

http://www.sendspace.com/file/jqa5jc

I just hope to have made them correctly. If you need any other
information just request it and I'll be glad to send it as soon as I
can.

By the way, the graphics card is an Intel Graphics Media Accelerator
4500MHD. I've googled about it and OpenGL 2.0 and I found that ir
supports OpenGL 2.0. However, I don't know if the linux driver that I'm
using supports it.

Thank you in advance,

Regards,

Mário Saleiro
