Re: [osg-users] Eclipse and OSG

Hi all,


#  = console command line
E# = action in Eclipse



I take for project example OSG.


1) - Prepare the build system
   Eclipse don't know how work CMake so we need to prime the pump

# svn checkout 
http://www.openscenegraph.org/svn/osg/OpenSceneGraph/trunkOpenSceneGraph
# cd OpenSceneGraph
# mkdir release  cd release
# cmake ..

you are now ready to only use eclipse. So launch Eclipse.


1) - Eclipse use

E# Menu - File -Switch workspace : choose the directory where
OpenSceneGraph directory is.
E# Menu - File - New - Project - General - Project :
give the same name to the project that the directory where is the code.
So OpenSceneGraph
In the Project Explorer window, you have OpenSceneGraph
[OpenSceneGraph/trunk] but this not yet a C++ Project

E# Right click on this line - New - Convert to a C/C++ Make Project :
Now this is a C/C++ project. Eclipse scan the project directory, index
the code, found binaries, ...

E# Menu - Project - Properties - C/C++ Build : change the build location
and select OpenSceneGraph/release
for me this look like this : ${workspace_loc:/OpenSceneGraph/release}

E# Control + B : launch the build

E# Menu - Project - Properties - Run/Debug Setting.
Press the New button and select C/C++ Local Application.
Set the Name (for example the name of the program)
Set the C/C++ Application
In the Environment Tab, define the OSG_LIBRARY_PATH
 if not already done in the Eclipse processus Environment
Click the OK button

E# Run - Open Run Dialog ...
Choose your application and click the Run button.
All work fine and you win.



Hope help someone.

Cheers

Hi David,
Thanks very much. The only problem am now having is that when I run, I
get the error message:
Error launching OpenSceneGraph. Reason:
Java.lang.NullPointerException. Have you got the same error before or
could you please guide me on how to go about it.

Thanks alot.

Hi felix,

  This mean you try to run a Java application. Are you sure that :

  - your project is know by eclipse like a C/C++ project ?
  - your do
 E# Menu - Run - Open Run Dialog - Select C/C++ Application and

2007-09-05 Thread Felix Bwire 
Hi David,
that is exactly what I am doing. the problem is that it is not giving
any binaries. Otherwise, am still trying to figure out what exactly it
is. I even tried eclipse for only c++. Am really grateful for the
guidance you're giving me.

Let me try again and I will inform you on progress.

Thanx,
Felix

Re: [osg-users] Eclipse and OSG

2007-09-05 Thread David Callu 
Hi Felix,

now I am able to run the osg applications such as osgviewer, osgconv,
 osgarchive and osgversion.


Great.

My question is, if I am to create a program, do I do so under the same
 OpenSceneGraph directory or it has to be a different one. And



   Understand that Eclipse is just a front-end for your development
tool-chain (emacs, gcc, gdb).
   If your application could be launch in a console without eclipse, your
environment is well defined.
I mean to say your 3rdparty library directory or everything need by your
program is accessible.
   Else you need to adjust your environment.

  It's the same thing for eclipse, but you can define specific Environment
variable
  for each application
  E# Menu - Run - Open Run Dialog ... - choose your application -
Envirnment Tab -New

  To have completion in case you use different workspace.
  E# Menu - Project - Properties - C/C++ General - Path and Symbols -
Includes Tab
add header directory of the library you need.

thereafter, what do I do.


 I am not sure to understand the question.
 Coding your project perhaps :-)

HTH
