There is already an open bug report about this: OP-576: GCS crashes on startup when initializing ModelView plugin
Oddly enough, that particular problem was supposedly fixed a while ago already: OP-76: Modelview gadget crashes in some GPUs - looks like there was a regression.

thanks, the trace you sent strengthens the idea that it has something to do with VBO, because your driver also states that VBO isn't available with your card/driver.

Honestly we should migrate to Qt3D there was already some work done on this direction by one developer. I believe the only thing missing from that is make the Qt3D sources part of the GCS compile process.
@XXL-Wing IMHO if you have the skills it would be better to use your time completing the migration than fixing the old lib. What do you think?

btw, the GLC Lib that's used in the ModelView is probably dead.
There's no update since July 2011 and it was built prior to 4.7, so it's going to be a problem in the future.
I believe that this is a reason why the ModelView doesn't work for Mac, if built with Qt 4.7 or above.

I think that Oleg is already working on it...

sure i can help, if there is something gong on let me know.
if not, i'll look into it.
what i am new to is Qt and all of its compile process and stuff. but i will find out how to integrate it :-)

Check hhrhhr's branches, let me know if you need any help.

olegs implementation seems to be rather mature already shows model and movel when moving the cc.... so this one is nearly finished....
some smaller things to be fixed...
maybe have a talk to him if he is finishing it.....

GLC_Lib is still alive, the last commit to the SVN was 7 days ago.

However I tried to upgrade to the SVN HEAD and it failed to compile.

Seems our issue is 64bit Mac and 64Bit linux.

Qt3D is a mess right now, there are several versions of it which is why I think this direction stalled?

[hhrhhr]

hello.
Qt3D will be released 12/Mar/2012
before this time is not even clear which version gets a release (Qt3D or Quick3D)
current status of these branches - SIGSEGV when usingQt 4.8 (but there is a small patch for Qt3D who did not get to the master branch)

Yes, Modelview has always worked when I compiled it on my 32Bit OSX system. Seems to be a pure 64bit problem as it works on Linux 32Bit also.

Isn't VBO still disabled by default? This is a runtime option you can enable/disable from the ModelView option page.

Exactly.

They should be for sure. This current issue is related to 64bit Mac and Linux platforms and is very likely something else.

I was thinking of doing the ModelView in OpenGL.
What do you think?

btw, what features will Quick3D/Qt3D bring that it's better than straight OpenGL?
Less raw OpenGL coding?...

Much less and cross platform quirks are considered. hhrhhr already has the bulk of it complete, we are just waiting to see what happens with Qt3D or QtQuick3D. We will also get mobile support thrown in to it for free as well.

If you watch the tutorial posted a while a go, Qt3D is really nice to use, animations (like working ailerons like you did before) also are fairly easy to do.

We also get model imports all pre-written and the less code we have to maintain the better!

Not when I tested it. I compiled the binary from source, started it and it crashed immediately.
