How to setting up Eclipse for OpenGL

Hi guys! :cool:

I'm dealing with a very interesting new problem today:
Setting up Eclipse for OpenGL (on a Mac OS X10.6)


I've created a simple OpenGL program to begin with - however it is not compilable.

The header looks the following:

Code:

---

#include <stdio.h>
#include <stdlib.h>

#include <GLUT/glut.h>
....

---

I get the following syntax error within the editor:

Quote:

---

Unresolved inclusion: <GLUT/glut.h>

---

And after the build, I receive even more errors:

Quote:

---

Undefined symbols:
"_glEnd", referenced from:
_display in hello.o
"_glFlush", referenced from:
_display in hello.o
......
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [Hello] Error 1
**** Build Finished ****

---

There seems to be a linking problem. Eclipse isn't able to recognize the header files and thus the OpenGL code.
I tried troubleshooting using the suggestions from the following link, but things didn't work out.


Any Suggestions? :frown:

it appears you don't have glut installed on your system, or at least not visible to your development environment.
search your hard drive for 'glut.h'. if it isn't there, you don't have glut installed. install it. i'm not a mac guy, so i can't help there.
if it is there, then you need to add that directory to your file include path in the project settings or makefile.
for the unresolved symbols, you need to do a similar thing for the glut libraries.

It is actually. According to the troubleshooting link above (and I confirmed this), the GLUT and OpenGL frameworks lie in the paths:

Quote:

---

/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/GLUT.framework/Versions/A/Libraries/

---

All the necessary libraries are in there.
But, how to access them?

Presumably you have not added these to your include and library paths. Search around in your IDE for a place to do that.

Library directories are usually called lib while include directories are usually called include. You need to add both for OpenGL and GLUT.

I added the full path to the header files this time and the errors vanished from the workbench.

Code:

---

#include </Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/OpenGL.framework/Headers/gl.h>
#include </Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/OpenGL.framework/Headers/glu.h>
#include </Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/GLUT.framework/Headers/glut.h>

---

Instead, I received an autoconfig error:

Quote:

---

Invoking autoreconf in build directory: /username/.../programname

sh -c autoreconf -i
autoreconf: `configure.ac' or `configure.in' is required

Configuration failed with error

---

No suggestions whatsoever? :(

Apparently, not many people are using Eclipse.

Your solution in post 5 is not very good. You should add the "Headers" directories in the proper place in your IDE (search around). You also need to add the "lib" (or whatever) directories in the proper place. Your original problem was not with the linker, but you will get a linker problem the way it is now. I'm not sure what's up with autoreconf but try fixing the directory problem first.

Eclipse is a massive pain in the arse in my opinion - choose a dedicated c / c++ ide instead

I tried something else again (this time in Eclipse Juno).
For the following properties:

Quote:

---

Projectname > Properties > C/C++ General > Paths and Symbols > GNU C > Includes
Projectname > Properties > C/C++ General > Paths and Symbols > GNU C++ > Includes

---

I've added both necessary Header paths.

Quote:

---

/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/OpenGL.framework/Versions/A/Headers/
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/GLUT.framework/Versions/A/Headers/

---

However, after building, I get another strange error this time:

Quote:

---

**** Build of configuration Build (GNU) for project Hello ****

make all
make: *** No rule to make target `all'. Stop.

**** Build Finished ****

---

Where is this coming from now?

I have a couple of other projects in Eclipse which I would like to combine with OpenGL. Thus - the choice - Eclipse.

I know nothing of Eclipse, but you seem to have added the "Libraries" directories in the wrong place. The Includes property should have the "Headers" directories added to it. The "Libraries" directories should be added elsewhere (perhaps in a property called "Libraries"). They are two very different things and both are needed. Keep looking!

AH - there's a typo in my post. It's

/Headers/

ofcourse.
Edited post above.

Where do you add library paths in Eclipse Juno?

I figured out how to make it run on Eclipse Indigo.
