Didn't you say that you do not know linux very well ? Then PLEASE, PLEASE
do not try to compile Mesa or GLUT yourself. Use the appropiate packages
supplied with your distribution (there are some, really).

Being a non-experienced user, you risk messing up your system otherwise.
Even as an experienced user, you mess up your systems package handling
unless you tell the RPM (I assume that your distribution is RPM-based)
database about what you installed in some way.

I bet if you had used the packages that came with your linux distribution,
SimGear had ./configure'd flawlessly. The best thing is if you try to
remove the libraries and header files you installed manually from your
system (if you know approximately when you did the install, find -cmin
helps - see "man find" for details) and install the corresponding RPM
packages afterwards.

No, please also don't do that.

Well - the configure program tries to compile a simple program that
includes pu.h. If the compilation process failes, then this does not
necessarily mean that the pu.h header file is missing or that something is
wrong with it - it could also be any of the header files included by it
directly or indirectly.

What wonders *me* is that when the Simgear configure script checks for
GLUT, no error ocourrs, while the compiler obviously cannot find the GLUT
header fine when checking for pu.h.

[de S. <de...@es...>]

well in fact i compiled plib with 

"./configure --with-GL=/usr/src/glut-3.7" so that plib found my opengl
directory because it dit not find it by default

after you told me to look at the log, i remarked there was a problem
with glut and i tried to configure simgear unsuccessfully with the
same argument, but it did not work

i'll try to copy my gl files in several directories untill it works
:-)
 (or link the dir)
the stupid fact is the configure script which says there is a problem
with plib whereas it is with gl dir.....

See the third last line. The GLUT header file is obviously missing on your
system or the compiler cannot find it.

If you compiled PLIB from source before, than I doubt that the file is
actually missing, since if it would have been at that time, you surely
wouldn't have been able to compile PLIB.

Try the following:

find / -name "glut.h"

(in case you do that as non-root, ignore the warnings about the directories
that find was unable to process due to their permission bits. System-wide
installed header files usually don't reside in these directories.)

If the file shows up either in /usr/include/GL/, /usr/local/include/GL/ or
/usr/X11R6/include/GL/, then everything should be fine (well, in the last
case Steve might argue that things are not fine - but as I can see from the
gcc commandline in the logs, /usr/X11R6/include/ is added to the
searchpatch, so there is no need for you to care about this issue for
now.).

In case the file doesn't show up at all, you've got a problem. However,
before trying to compile and install GLUT manually, *PLEASE* grab your
distribution's CD and locate the package(s) containing the GLUT library and
header file. Then, try to install these again.

well, i will only be able to send it on friday, but i remember it
stops on output

checking for plib/pu.h...no

yous *must* have plib installed on your computer....

configure aborted

as soon as i am able to post the log, i'll do it

sorry for my bad english, i'm french

______________________________________

i got a problem while installing simgear, and as i don't know linux
very well, i do not know if it comes from simgear or plib install

just after i've installed plib, in the "./configure" step of simgear
install, it says it cannot find plib/pu.h in the right directory,
although files are where needed...

Might it be a problem in plib install ( some tools might be unable to
detect that plib is corectly installed) or an error in simgear's
configure sript ?
have any of you ever met this problem ?

It does change state without restoring it - yes.

That's not accidental though - it's very inefficient in OpenGL to keep
setting and restoring state unnecessarily - so we leave it to the
application to save and restore state if it wishes to.

Many applications (all of mine) get away without doing that and are
faster as a result, others can do things like not restoring all of
the detailed texture attributes because they just glDisable texture
globally.  So, it's better to let the application decide.

As a first shot at fixing this, you could wrap ssgCullAndDraw with

  glPushAttrib ( GL_ALL_ATTRIB_BITS ) ;
  ssgCullAndDraw () ;
  glPopAttrib () ;

...that will almost certainly fix your problem - but at some performance
cost.  If you find that cost is acceptable - then you're done. If not
then you'll have to ascertain which things that SSG changed are not
acceptable to your draw_water() function.

RE: [Plib-users] Newbie Question: Mixing SSG & OpenGL

[Stanford N. <st...@th...>]

Thanks for the pointers!

After much digging under the hood of my program, I'm still encountering
problems with mixing SSG & OpenGL.  I've narrowed it down to the
ssgCullAndDraw() call influencing the GL state somehow.  When I comment
out ssgCullAndDraw() in my redraw routine, the draw_water() works fine,
drawing a blue rectangle.  When I leave the call in there, the rectangle
is still drawn, but it is very dark and blends right into the
background.  

I'm trying to puzzle out what ssgCullAndDraw() is doing that would

Well, all of my games do - so check out TuxKart for example.

I doubt that it's been done before - but that shouldn't matter.  So long
as you can get a valid OpenGL rendering context, you should be able to use
all of PLIB's features.  That means that you could even use SSG to render
objects into the Inventor window - not that this is necessarily very
useful!

[Plib-users] Newbie Question: Mixing SSG & OpenGL

[Stanford N. <st...@th...>]

Hi everyone!  I just got started with Plib and I like it a lot!  Great
work, guys!

I'm stuck with a rather embarrassing problem: I can't seem to mix SSG &
my OpenGL code together.  My SSG code loads a model and displays it.  My
OpenGL code draws some colored polys to the screen.  They both work
individually, but I can't mix and match...

It seems that the ssgInit() call will setup some GL state that causes
the GL calls in my custom code to not render... This is rather
perplexing as I have managed to work the 2-d font rendering via an 2-d
orthogonal projection into the code.  Is this something obvious I'm
missing?  

If someone could point me to an example that has both SSG & OpenGL code
working together, I'm sure I can figure out what I'm doing wrong.

Thanks in advance!

Yes - recently someone tried to do so. It requires that you enable the PUI
non-GLUT hack I described in my previous mail.

The sound and joystick libraries can be used with almost every application.

The FNT library just requires an working OpenGL context.

The PUI library requires that you construct your OpenGL windows with GLUT
by default. This is a rather complicated issue. There is, however, a
recently often-discussed hack that allows you to use PUI independently of
GLUT.

For details, scroll down to the bottom of the PUI documentation at
http://plib.sourceforge.net/pui/. All you have to do is basically to
compile PUI with the preprocessor macro PU_NOT_USING_GLUT defined and you
must define this macro just before including "pu.h" from your application.
Furthermore, you must ensure that three font texture files are present in
the current directory at runtime with the GLUT-less PUI and feed PUI with
window dimensions through puSetWindowSize () as said in the documentation.
Additionally, note that you can not spread PUI widgets across multiple
windows if PUI was compiled with the non-GLUT hack enabled.


I hope I could help you,

Probably lack of money to buy the hotel bill; AFAIK does anyone who
gives a speech travel for free (ask Alex).

I hope you can do it next year. So I have a realistic chance to drink a
beer with you!

Sorry to have bothered you all with the specific question about the GLUT

I puwith Inventor.  Has that been done before?  (I realize that means ignoring

[Plib-users] Is PLIB 'compatible' with Open Inventor and Qt?

[Mark H. S. <sh...@pt...>]

I'm trying to figure out whether PLIB will help in an application
I'm working on.  The application is built on Open Inventor and Qt.
Is PLIB compatible with those choices?

I particularly want the fonts and text library but could make good
use of sound, the joystick, and PUI libraries.  I've downloaded PLIB
and the examples and compiled them under windows, and everything
worked very nicely.  The examples depended on GLUT, but I'm
uncertain the degree to which PLIB itself also depends upon it.
  Thank you,

As I said. However, I don't believe you the money thing - remember the

Lack of time to take out a week to fly to Germany and back - lack of
money to buy airline tickets and a week of hotel bills.

But not lack of interest.

Are you sure that it is lack of interest ? I'd say what we are talking
about is perhaps lack of money, but most likely lack of *time*.

Nevertheless, thanks for your efforts ...

All the documentation there is is on the http://plib.sourceforge.net

There are no explicit tutorials - but LOTS of example programs in the
'examples' and 'demo' areas.
