Hello Folks,

I hope someone can give me a hand on Ogre3D and Linux.

I use Ubuntu 9.04 and have (i guess) everything intstalled to compile progams with PB4.31
I wanted to test the camera example provided with PB.

I get no errors when compiling but when hitting the run button simply nothing happens.
No errors but also no 3D Screen

I tested it even with OpenSuse 11.0 - same thing: compiles but no 3D screen.
I put the engine3d.so in /usr/lib - no effect.

PLEASE - DID ANYONE OF YOU SUCCESSFULY GOT THE 3D ENGINE WORK UNDER LINUX - AND IF SO - HOW DID YOU DO THAT?

I would be really grateful for a hint!

Thanx in advance !
Andi

Hello Andi,

When I compile with debugger Camera.pb I get error in Screen3DRequester.pb and line 50. The error is Invalid memory access. Did you try to compile with debugger?

Line 50:

Code: Select all

    If ExamineScreenModes()

Did you used the 'OpenGL' subsystem ?

Posted: **Fri Jul 03, 2009 4:32 pm**

Hello,

I tried it with OpenGL subsystem - no success. Same behavior

I don't get an error if compiler is turned on.

Thanx for your time.
Any other ideas?

confirmed (pb 4.31 - subsystem opengl)

it seems, that InitEngine3D() doesn't find the engine3d.so even if it's in the same Directory!!

Workaround: copy engine3d.so to /usr/lib/

There are some other commands not working (i'll post a bug report for each one)

Hello,

I have already tried with engine3d.so in /usr/lib - unfortunately no success

Hi,

did you run 'ldconfig' after copying the lib to /usr/lib ?

I think else the library is still not 'findable'.

Best regards,

Bernd

Hi,

yes I ran "ldconfig" after copying engine3d.so to /usr/lib.

But it's all the same.

Hi,

now I tried it also to run Camera.pb on my Kubuntu 9.04:

At first InitEngine3D() gives an error.
So I copied engine3d.so to /usr/lib and this problem was solved.
Than I tried to run the compiled Camera. (Subsystem: opengl)
This results in an error: 'cannot open display:'
Ok, my fault, I tried to run it as root.

As normal user still a segmentation fault appears:
'creating resource group General Segmentation fault'
I found out, that I have to install the libxxf86vm packet.

Now I can start the program, the select window (full screen or windows)
appears, but when I select something (better window), than the next stuff is:

Code: Select all

Any ideas ?

Hm,

I read, that the Ogre system needs real hardware.
At the moment I use VirtualBox 3.0.
I'll check it this evening at home on a real PC.

@Bernd:

Hey that sounds interesting ! I'm a the office right now but I will test this
as soon as I'm back home.

Same problem here
I just puschase full version and tried of cource also 3d samples.
All (camera.pb, terrain.pb... ) gives error on ExamineScreenModes() ...invalid memory access
I also copied engine3d.so to /usr/lib/..

But following small example in PB-help from command page NestScreenMode
.. works fine.

Code: Select all

InitSprite()
  If ExamineScreenModes()
    While NextScreenMode()
      Debug Str(ScreenModeWidth())+"x"+Str(ScreenModeHeight())+"x"+Str(ScreenModeDepth())+"@"+Str(ScreenModeRefreshRate())+"Hz"
    Wend
  EndIf

So , any progress or is there some conflict with Ogre and PB.

I tested same stuff with PB4.30 version, ..example progs worked to point where it asked what window mode is requested, after that it says program execution has finished
and nothing appears to screen.

Posted: **Thu Jan 14, 2010 8:09 pm**

I'm having the same problems as everyone above.

I'm running Kubuntu 9.10.
PB is fully installed, all my graphics drivers are up to date.
I tried copying engine3d.so to /usr/lib, and running ldconfig.
I still get the Invalid Memory Access error on line 50 of the 3D screen requester program.

I even installed Ogre 3D itself on my system to see if it would help.

No luck.
