error running openGL/Ada demo from GLOBE_3D using GNAT 2012

error running openGL/Ada demo from GLOBE_3D using GNAT 2012

[Nasser M. Abbasi]

has anyone managed to run the demos Ada openGL demos in GLOBE3D?

I downloaded the latest GLOBE_3D from

http://sourceforge.net/projects/globe3d/

then went to the demo folder, and build using the linux gpr
file there. All went OK:

>gnatmake -P globe_3d_gps_linux.gpr

Now, I am following the direction in the .html that comes in the
above tar file, and when I try a demo, I get an errors:

Hi Nasser,

Either (1) the archive file "g3demo_global_resources.zip" is not in the same directory as the "mini" executable, or for (2) some reason the file "face1.bmp" is no more in the mentioned archive. If the archive file is broken, you would get another message.

I have improved the diagnostics (on the globe_3d repository version), and for the case (1) you would get now:
Execution terminated by unhandled exception
Exception name: GLOBE_3D.DATA_FILE_NOT_FOUND
Message: g3demo_global_resources.zip

Hope this helps

hi  Gautier;

2 issues:

1) I had unziped those file before (I did not know) when I unzip
files, I unzip them and delete the zip files).

I restored the zip files, and run mini and now I get this error

btw, the file Face.bmp is there, but it is Face.bmp and
not face.bmp (i.e. lower case). I am on linux. Does this
make a difference? could this be the problem now?

I am mainly now interested is using the open GL binding

I have tested today latest changes on Windows 7 32 bit, Windows 7 64 bit, Ubuntu 10.04 32 bit without any issue.

No, since the image files (and other data) are only read in the 2 Zip files, in a case-insensitive mode. At this stage the operating system has no control anymore on names and their case-[in]sensitiveness...
What happens when you run the Linux executable that is shipped with the whole stuff ? - I mean: ./globe3d_demo_linux ?

Sure. And it uses the modularity ([Gl.]Name) instead of glNAme of the flat macro-assembler model. And also uses name overloading, like Vector instead of glVector3i, for instance.

That is what I tried first time I downloaded the software, before
doing anything, but I get this error

THat is why I build things. I am using GNAT2012 on linux, not the earlier
gnat version. i.e. I downloaded gnat2012 from Libre and installed it.

All my other gnatmake commands on my toy Ada programs compile
and run with no problem, so I assume all the paths and
env. variables I need to use Ada are ok as is, or do
you think I need a different env. variable in addition to
what I have to make your above program run?

Ok, this what I tried now, since the shared library linked to by your
program is different, I made a sym link. Now it runs, but a new error
comes up:

btw, would it not be better to have those prebuild demo examples in the
distribution demo/ folder be build as static instead of shared? so
that to eliminate the shared library being different on each system.

I am no expert on this, but something to consider.

That is why I was trying to build the demo files myself. But
due to that texture error, can't run them.

thanks.

I could not agree more! These are kind of things I am learning progressively, like the advantage of -static, on another project. Also kind of annoyances you don't know on less refined systems (I am used to a clunky, commercial one called Windows).

Absolutely, it solved lots of problems on that other project.

I'm afraid you went past any problem with texture loading if you get that message (your post after having restored the .zip files):

It looks like an OpenGL issue with your Linux installation.
Perhaps a plain Ubuntu would help ? Everything fine with other OpenGL-based software ?...

I am following instructions in

      GLOBE_3D/globe_3d_info.html

where it says

"As a prerequisite, you need the following libraries to
be installed: FreeGLUT, Xi, Xext, Xmu"

I have all of these. Instructions doe not give specific versions,
so I made sure all these libraries are on my linux system
(they must be, else it will not link)

Btw, there is no "FreeGLUT" library. There is freeglu3 .deb
package, which I have installed. It supplied /usr/lib/libglut.so

I have libGL.so, libGLU.so, libglut.so, libX11.so,
libXi.so, libXmu.so, libXext.so and libm.so

If there are more specific instructions as what versions
of libraries one needs, that would be better. For me to just
keep trying different linux distro and different libraries
by random in the hope it works, is not very productive way to
build something.

what constitute openGL?  i.e. which libraries make up what is called
'openGL' ?

I am used to seeing an architecture diagram for applications, as
building blocks, so I know what depends on what, and what libraries
make up what block in the diagram. The apps at the top, and blocks
below it, and such.

If I understand more the architecture used here, I might be able
to figure what is the problem with this binding in terms of
mismatched libraries.

Right now, I just have lots .so's that I installed from packages. But
I really do not know which of these is openGL and which is what. And
I do not know what versions. I just use linux mint package manager
to install things. I assume it knows the correct versions to install.

> Perhaps a plain Ubuntu would help ? Everything fine with other OpenGL-based software ?...

DO you have an example of what other openGL I can try? I never done openGL
before.

I do run your demos on windows, and they run with no problem. But
not on Linux mint as you can see.

Obviously the needed libraries are installed, otherwise you would not have an executable. And it doesn't seem to have unresolved symbols in shared objects when startting mini.
Now from the error message:

"OpenGL Warning: XGetVisualInfo returned 0 visuals"

it seems OpenGL doesn't find any device to display on.
The back-end of OpenGL is dependent on your OS and your graphics hardware and virtualization layers.
Like most graphics-related issues, these are difficult ones.
By googling the above message, it seems correlated to VirtualBox and its configuration.

No clue of any other OpenGL example / test for Linux. Anyone ?...

Sure, I know that, and I said before the link was fine.

Ok, some good news, and some not good news. First, the good news.

Yes. the display issue was VBox issue with. I googled and find a solution. The
command to start the demo is

>LIBGL_ALWAYS_INDIRECT=1 ./mini

here is a screen shot, it is comes up OK:

http://12000.org/tmp/071512/globe3d.png

I found this solution at this page

https://forums.virtualbox.org/viewtopic.php?f=3&t=30964

by poster called scottku. (down the page) It seems the above disable
harxware acceleration. And that fixed the problem.

Now the bad news :) For the other demo, globe_3d_demo_linux, the
above trick does not work. The error is a build error. Even
though I did gnatclean few times and rebuild things again
and again.

>LIBGL_ALWAYS_INDIRECT=1 ./globe_3d_demo_linux

./globe_3d_demo_linux: Symbol `system__restrictions__run_time_restrictions' has different size in shared object, consider re-linking

./globe_3d_demo_linux: symbol lookup error: ./globe_3d_demo_linux: undefined symbol: __gnat_eh_personality

I do not know why mini demo works OK, but not this one. So, I think
there is still a library issue here?

I am using your gpr with no changes to it (i.e. gnat05).

Thanks for your help. May be some progress was made.
  
At least now, I can try to make a small Ada openGL program myself
to see how it works.

The executable freshly built is called "globe_3d_demo".
Unless you've renamed it, "globe_3d_demo_linux" is still the old 2011 file with fragile shared object linking :-) .

NB: the .gpr for next release has now "-static", so you would not get this message in a similar situation.

Yep, that was it! I was running the linux executable, as I assumed that
is what is being build, being on linux.

You might want to change the .gpr so that when it builds the demos, it
still makes a  _linux version of the demos and _win version (when on windows)
just to be consistent with the orginal file names as they came with the
package.

But now both demos are working ok on Linux. Thanks for your help.

Yes, static build would be better. thanks.

I do. It is an excellent idea. How can I do that, in order to have "globe_3d_demo" -> "globe_3d_demo_linux" ? With a "-o" build (gnatmake) option it would give the same name to all executables, I guess. Well, I could have only one "main" for the "Small" build scenario which is there for shipping anyway.

You are welcome, and sorry for the confusion(s).
