Dear Open Inventor Developers,

We would like to compile Open Inventor using gcc on IRIX, since gcc/g++ has
some nice features that IRIX CC lacks.

I downloaded "inventor-2.1.5-6.src.tar.gz" and I changed the compiler 
definitions to GCC/G++.  My operating system is 6.5.9m on an O2 machine
 and I am using this gcc:

Reading specs from /usr/freeware/lib/gcc-lib/mips-sgi-irix6.2/2.95.2/specs
gcc version 2.95.2 19991024 (release)


I was able to compile some routines, but it failed at this point

It only gives some warning message but what the real error was.   Does anybody 
have some suggestions to solve this problem?  
Thank you very much for your help.

Hi. I'm a new to the list and new to linux development, but not
new to OI development.  I just ported a bunch of SGI ViewKit GUI
code to straight lesstif/Motif on my home system.  Arg! - and now
just seeing this group and this thread I realize that I won't be
posting many questions to comp.graphics.api.inventor any more. I
had asked about whether I could get OI components working with
Glade - the stock GUI builder that came w/ RH7.0.  There was no
response.  I *did* manage to get Glade to generate c++, but only
after working through several layers of lib dependencies...

So - I'll pose the question to the gurus -

  Of the two options mentioned in this thread -

- http://www.geocities.com/angbodhi/download/

- http://www.coin3d.org/

Will either of these work with Glade/Gtk+?  ...and if so, is either
a "better" choice?

Thanks -

Bruce

The error message is indeed there, you just probably overlooked it.

Most probably (on the other hand, does OSOIV not use SGI native Image
Liberary when compiled on SGI?) . Look at the nearest opensource
archive for `jpegsrc.v6b.tar.gz' which is I guess the last verison of
the library.

Hello,

I am trying to recompile OpenInventor on IRIX 6.5 (IRIX64 E6 6.5
04191226 IP30) and I have some problems :

I am using the sources from inventor-2.1.5-6.src.tar.gz
I am compiling with /usr/bin/CC -mips3 -n32

The libInventor.so and libInventorXt.so are generated but, when
installing, the ivman program do a segmentation violation. This is the
stack I got by running ivman with gdb :

Program received signal SIGSEGV, Segmentation fault.
0x5b28dfc in getClassTypeId__9SoElementSGv () at SoElement.h:120
120         static SoType       getClassTypeId()        { return
classTypeId; }
(gdb) where
#0  0x5b28dfc in getClassTypeId__9SoElementSGv () at SoElement.h:120
#1  0x5b29748 in initClass__20SoAccumulatedElementSGv () at
SoElementInit.c++:161
#2  0x5b28e90 in initElements__9SoElementSGv () at SoElementInit.c++:70
#3  0x5d4b550 in init__4SoDBSGv () at SoDB.c++:202
#4  0x10005de0 in main (argc=3, argv=0x7ffefe24) at Main.c++:119
(gdb) up
#1  0x5b29748 in initClass__20SoAccumulatedElementSGv () at
SoElementInit.c++:161
161         classTypeId =
SoType::createType(SoElement::getClassTypeId(),
(gdb)

Every example/demo I link with the library crash at the same place. By
playing around with the source, it seems that after
SoElement::initClass(), each call to SoType::get* dumps a core.

I even tried to "purify" everything but nothing strange appeared.

Why is this happening ???

I'll be very happy to have any suggestion...

Ah, that's a bug in your c++ front end of your compiler.

Fix: install the latest patches.

http://support.sgi.com/colls/patches/tools/relstream/index.html

in the product category select 7.2.1.3 (if you have a 7.2 style MIPSPro 
compiler)
or 7.3.1.2 (if you have a 7.3 style compiler)

to get your current compiler version number: cc -version

cheers,
-g.

Inventor uses the famous jpeglib on IRIX, Linux and Windows ;-)
The first cvs snapshots used an very old version of jpeglib which was included
in the so directory of inventor.

or grab a pre-compiled version from

You'll find a lot of the same people here as in cga.inventor.
I'd post questions specific to SGI Open Inventor to this list and
questions generic to any Open Inventor to cga.inventor, but that's
just me :)

I'm not familiar with Glade.  However, as one of the Coin3D SoGtk authors
I can tell you that no efforts has been made to make SoGtk work with Glade,
so if Glade requires some special support, you'll not be able to use them
together.  I would suspect that Glade needs GUI components to be managed
more or less completely by their base widget (in the case of compound
widgets), while SoGtk "widgets" are really managed through their own C++
component class system.  So just based on my speculations, I'd say "no".

No, not without more work. I think this apply to either choice.

However, I think its possible to add Open Inventor SoGtk widgets
to glade. Looking at internal of glade, a widget's creation, set
property, get property, etc are done through "user" provided
functions (as oppose to functions internal to Gtk+), so its
technically possible to create SoGtk components and send back the
component's top level widget via getWidget(). One problem is
signal connection will not work with the SoGtk components because
glade sees only the top level container widget. An alternative way
is to provide Gtk wrappers to SoGtk components. Glade is designed
to allow additional modules of Gtk widgets to be plugin, but as of
0.5.11, this loading of plugin is still a dummy implementation. So
it should be possible to add a SoGtk module in future.
A quick hack to glade here  ;-)

Another consideration is whether libglade will be able to
dynamically create SoGtk widgets on loading the XML file generated
by glade. But similar mechanism seems to be used, so it appears
possible.

Ang and Lars,

I'll re-pose my original question then - since I'm a way better
Inventor programmer than an Xt/GUI programmer - I was hoping to
avoid more "manual" GUI generation...

Are there any Linux gtk+ GUI builders that I'll be able to get
working with either of these OI component sets?

Hi,
  I'm trying to make a real-time visualization model using Inventor. I
want to update the position of the actors in my scene graph based on some
calculations. i.e
I have
robo_trans->translation.setValue(robot_x,robot_y,0.0);
After some calculations, the values of robot_x, robot_y change. I want to
render the scene with the changed values. Thus showing the effect of the
object moving.
Could someone please tell me how to do it..

Thanks,
Arvind

Sorry, I don't know of a Linux gtk+ GUI builder that work with
OI components set.

BTW, its strange I saw your message from SGI's mailing list thread page,

but I did not receive your mail from the mailing list.....

No.  Maybe later, but not now.

Please read the chapter on using Engines in the Inventor Mentor. There are also
a number of examples that come with the source.

Hello,
  I had posted a query y'sday about updating object states in inventor. I
saw the calculator example. I need to do something similar to that(plan a
path). Only difference is that my path has already been computed and I
have  3 floats that give me the objects coordinates.
I have an initial position (x,y,0) and a set of positions(floats). I tried
to use the Calculator engine but couldn't get it to work. Since I don't
have a time or any other counter, what do I give to
calcXZ->A.connectFrom(...)

Any help is appreciated..
Thanks,
Arvind

Use a SoAlarmSensor ... when it fires, change the object's coordinates. See
12.3.AlarmSensor.c++ for details.

It would be more efficient if you used a callback to update states on 
a regular basis instead of using the caculator. The calculator is useful 
if you need to define some simple procedular behavior. For anything 
more complex, I would write my own engine, or just use a callback. In 
your specific situation, the callback seems like the best way to go.

You can define a callback with SoOneShotSensor. Assign some high
priority to the sensor, say 1, and your callback will be pretty much the 
first thing that Inventor's event manager will call every time it needs 
to update the scene. Inside the callback of SoOneShotSensor, do your 
operation (such as updating the position of an object), and then 
reschedule the same sensor again. This will let you reuse the same 
sensor over and over and your callback will get constantly called.

If you need some complex event management, you may want to consider
writing your own event manager to replace Inventor's.

Jonatham suggested that you use SoAlarmSensor but if you use that sensor,
you are tied to processing your events every so many timer units. If you 
use SoOneShotSensor, you will be processing them as fast as you possibly
can.

    Jonathan,

    Last time I reported that the SUN Solaris version appeared to work
except for the middle mouse translate action. That problem is fixed. (It was
just an inadvertant type-o I introduced to one of the files.)

 I did alot of side by side (SUN/SGI) stepping through the debugger and
examining variables so I am confident it is working ok. (At least all the
functionality of an SoXtExaminer viewer with an SoCube in the scene.)

 The only other issue I wish to clean up involves the JPEG library.
Previously I had reported:

	>>     - I had to "gut" all the methods in "SoTexture2.c++" since it
included
	>>       "jpeglib.h" which I did not find. (This means SoTexture2 is
not
      >>       usable but links ok).

and you replied:

     > You should be able to download the JPEG library and build it for
Solaris

 Where is the JPEG library? I did not see it as part of inventor.

It's no longer part of Inventor (eearly CVS snapshots contained it).
Grab it from

Hello sorry to bother you,
I hope this is the correct place to submit my querry if not I appologize.

	I have just downloaded open inventor 2.1.5-6. I am running
openmotif 2.1.30, g++ 2.95.2, glibc 2.2.2, redhat 6.2.  I have been able
to get open inventor to compile but when it runs,ie ivview for example,
all the menu fonts are boxes. When I click on the open file I get boxes
everywhere but in where you can enter text. I was wondering if you knew
what I missed to cause this. Whether it is open inventor or something else
I have done I am not sure.  I did run the linkType1.sh and moved libFL.a
into the /usr/lib directory. I have the Utopia fonts and everything.  Is
there a specific font it is trying to lookup or it is something in my
preferences I need to change.  I tried to figure out with strace but could
not get a definitive handle in my mind what was going on.  Is it something
I screwed up and if so how can I fix it, or is there something I need to
download and compile against to get it to work. Hope you can help.

Hi,

I am looking for a possibility to save a scenegraph as a vrml2-file. I am not
interested in using a converter like ivToVRML and vrml1tovrml2. Or maybe a
library to create vrml-Nodes and save them afterwards.

any ideas ?

Matthias

I suppose you are looking for an open source solution, :-) but
FYI, Open Inventor from TGS includes all the VRML97 (aka VRML2)
nodes as native classes.  You can create a VRML97 scene graph
exactly as you want it written out or convert a "classic" OIV
scene graph to VRML97 nodes and write them out.

Hi,

Here are some minor compilation errors and fixes for the latest CVS (I got
it earlier today), with gcc 2.95.3:

SoLODV2.c++:
problem: FLT_MAX undeclared
fix: <limits.h> should be <float.h> (limits.h is only for integral limits)

SoGLRenderAction.c++:
problem: FLT_MAX undeclared
fix: include <float.h>

Sb.c++:
problem: implicit declarations of localtime() and strftime()
fix: include <time.h>

GeneralizedCylinder.c++:
problem: The statement "delete [] spineKeyPointRotations;" causes an
internal compiler error.
fix: Unknown, wait for the next gcc version :).

Also, something which is not an error, but isn't it possible to determine
automatically whether the glw... or glwM... functions are
available? "GLwMDrawA.h" basically looks like this on my system:

--

#ifndef __GLX_MOTIF
#define __GLX_MOTIF 1
#endif
#include "GLwDrawA.h"

--

Isn't it possible to include only "GLwDrawA.h", and then define
__GLX_MOTIF depending on which library is available. I guess this requires
some kind of autoconf system? Or maybe there is a better solution which
I've missed?

Finally, the demos "drop" and "noodle" segfault on my system, are they
supposed to work? I guess this is not a very big deal though (assuming
noone requires the functionality which segfaults).

  Johan

Hello,

I'm a french student (so sorry for my english !!).
I do research on 3D Mesh and I want to import ASCII Open Inventor file in my
software. My software doesn't use Open Inventor.
So could you give the structure of the ASCII Open Inventor file.

Thank you for your help

Mime-Version: 1.0

Hi,

I am new to Inventor, and I am using Red Hat 7.0, which is not officially 
supported, so if anybody knows of any problems specifically with Red-Hat 7, 
please drop me a letter.

But the main question is as follows:

I have installed all the necessary packages (lesstif, Mesa ..) and 
successfully deployed 3 Inventor's RPMs.
When trying to compile the following simplest program, the compiler could 
not find Xm.h, which was supposed to be in /usr/lib/Xm. This is the header 
file of Motif.
So I tried to install OpenMotif, but it came ( not a miracle) with a 
conflict with libraries of lesstiff. After uninstall of Lesstif and 
installation of OpenMotif, Inventor could not be installed, since one of 
libraries was missing. So what is the reason of all this mess? It is 
specified in FAQ, that either motif or lesstif are equally supported.

Then I restored the original installation, and found that there are needed 
libraries and header files in /usr/X11R6. Finally I succeeded to compile 
the program, but it did not work - it showed only empty brown window, 
without any text in it.

I have no idea what is the reason for all this, and would greatly 
appreciate any help.

Another question : does anybody know about any sort of incompatibility on 
the source code level between Linux version and SGI version of Inventor?

This is the program I talked about:


/* hmw0.c */
#include <Inventor/Xt/SoXt.h>
#include <Inventor/Xt/SoXtRenderArea.h>
#include <Inventor/engines/SoElapsedTime.h>
#include <Inventor/nodes/SoCone.h>
#include <Inventor/nodes/SoDirectionalLight.h>
#include <Inventor/nodes/SoMaterial.h>
#include <Inventor/nodes/SoPerspectiveCamera.h>
#include <Inventor/nodes/SoRotationXYZ.h>
#include <Inventor/nodes/SoSeparator.h>
#include <Inventor/nodes/SoText3.h>
main(int , char **argv)
{
    // Initialize Inventor and Xt
    Widget myWindow = SoXt::init(argv[0]);
    if (myWindow == NULL) exit(1);
    SoSeparator *root = new SoSeparator;
    root->ref();
    SoPerspectiveCamera *myCamera = new SoPerspectiveCamera;
    root->addChild(myCamera);
    root->addChild(new SoDirectionalLight);
    // This transformation is modified to rotate the cone
    SoRotationXYZ *myRotXYZ = new SoRotationXYZ;
    root->addChild(myRotXYZ);
    SoMaterial *myMaterial = new SoMaterial;
    myMaterial->diffuseColor.setValue(1.0, 0.0, 1.0);  //RGB
    root->addChild(myMaterial);

    // The screen's text
    SoText3 *myText = new SoText3;
    myText->string = "Hello CG Course";
    root->addChild(myText);
    // An engine rotates the object. The output of myCounter
    // is the time in seconds since the program started.
    // Connect this output to the angle field of myRotXYZ
    myRotXYZ->axis = SoRotationXYZ::X;     // rotate about X axis
    SoElapsedTime *myCounter = new SoElapsedTime;
    myRotXYZ->angle.connectFrom(&myCounter->timeOut);
    SoXtRenderArea *myRenderArea = new SoXtRenderArea(myWindow);
    myCamera->viewAll(root, myRenderArea->getViewportRegion());
    myRenderArea->setSceneGraph(root);
    myRenderArea->setTitle("Hello Computer Graphics Course");
    myRenderArea->setBackgroundColor(SbColor(0.35,0.35,0.35));
    myRenderArea->setSize(SbVec2s(600,600));
    myRenderArea->show();
    SoXt::show(myWindow);
    SoXt::mainLoop();
}

With LessTif 0.91.4, try

  /usr/X11R6/LessTif/Motif1.2/include/Xm/Xm.h
  /usr/X11R6/LessTif/Motif2.0/include/Xm/Xm.h

I don't see why having OpenMotif would be a problem, even though I built the
libraries using LessTif. All that's required is libXm.so.

The source code is exactly the same for any operating system.

Hi, Jonathan,

This was correct. I did it, and there were no any complaints on the 
compilation stage

libInevntor.so requires libXm.so.1, which seems to be missing in Motif.

How should I know, if my fonts set up properly or not?
But what I found in Problems note, that " SoText[23] is currently not 
supported with Linux version".
Does this may be the reason for the program not to work? I mean, I use 
there SoText3 to print the text on the screen. If it is so, what is the 
alternative, which may be used to print the text on the screen?

Thanks again,
Mark

I will be checking in the FreeType interface in the next couple of days, so if
anyone wants to look into testing it and fixing any potential problems, please
do so at that time. Thanks.

Jonathan,

I've fixed some problems of Ang Bodhi's libFL wrapper to Freetype.
1) a small memory bug
2) the font size was constant (32 points)

The fix has already been uploaded to Ang's site.
Be sure that you use this version. Try to use an SoFont and SoText2 node
and play around with the size field. If the font size is changed you have
the latest version.

Cheers,
Gerd

Hi there,

I wonder if you could help me, I have just aquired 2 Space Balls in an
auction and was wondering where
I might find drivers or leads for them. Apparently and much to my amazement
they were developed by DLR
many years ago to assist astronouts. The cost then being thousands of
dollars, where as I picked mine up
for a fiver. Anyway, are these curious antiques going to end up as after
dinner topics of conversation or can
you point me to additional resources such as drivers cables etc so that I
can experince them working on my
Win PC?

Many thanks

Jonathan

Astronauts ... Space Balls - it figures.  What kind of sports/games did
they use them for?  ;)

Couldn't resist.  Sorry I can't be of any help, though...

Hi,

  I am having problems compiling SGI's Open Inventor on my

Please let me know if you know why I am having problems.
I did modified this file "/proj/sgi/Inventor/inventor/make/system"
and set the "usingLinux = 1".

Thank you,

Edit make/ivcommondefs and uncomment the following lines:

  # MATHDEFS = -D_DOUBLE_MATH_ONLY
  # LCXXDEFS += $(MATHDEFS)
  # LCDEFS += $(MATHDEFS)

If you're compiling on Solaris, why are you setting it so?

Hi Jonathan,

  I put back the "usingLinux = 0" and had to change the "/usr/bin/CC" to 
the g++ one.  However, it went well until I got to the
so/nodes/SoText2.o with this error:

Hi,

  I finally got the libInventorXt.a and libInventor.a compiled on
SunOs 5.7 but I am getting these undefined symbols in the

I did include libFL.a.  Do you know why I'm having these undefined symbols?

Thank you,

Use nm to see wether flMakeCurrentFont is included in libInventor.a or not.
(also use nm on libFL.a)
If libFL.a has troubles, try the libFL wrapper for freetype lib (see latest 
cvs snapshot).
Based on that info you are able to resolve the problem.
maybe some functions are compiled as C++. you are able to identify this by 
looking at the actual function
name (output by nm). if it is mangled you have to define C linage style.

iclose is part of the image library. Seems that it is not included in your 
libInventor.a
(same problem with sqrtf. part of the standard math library. is -lm 
included at the inventor link line?)
Again, nm is your friend.

Cheers,
Gerd
