linux examples make

[sbin]

hey,
i want to start with irrlicht.
surfer@sbin:~/04/examples/1.HelloWorld$ make
g++ main.cpp -o example -I"../../include" -I"/usr/X11R6/include"
-L"/usr/X11R6/lib" -L"../../lib/Linux" -lIrrlicht -lGL -lXxf86vm -lXext
-lX11 -lz -ljpeg
/usr/bin/ld: cannot find -lGL
collect2: ld returned 1 exit status
make: *** [all] Error 1

I don't now what's wrong.
Maybe the path from the lib. big confused.
I use debian 3.0 (g++3.3)

Looks like the compiler is not finding the libraries for openGL.
You would have to find out where are they located in your system and their location to the makefile.

ok ihave instal some opengl cl-sdl-opengl ...

but why come this Warning message i think glx is a Open GL

Hello !

I updated my Linux (Mandrake 8.2 -> Mandrake 9.2)
Under Mdk 8.2, there is no problem to compiling examples, but now ...
And I got the same problem.

any idea ?

[Soldier of infortune]

I modify this line to remplacing DT_DIRECTX8 by DT_OPENGL in examples.

Code: Select all

device = createDevice(	video::DT_DIRECTX8, core::dimension2d<s32>(800,600), 16, false, true, &receiver);

And i got a seg fault
Before my update, there is no error.

but why come this Warning message i think glx is a Open GL

The warning means that the DirectX driver is not available in Linux and therefor OpenGL is used. So, ignore this warning, the examples work fine.

[Soldier of infortune]

I got the solution ! We must compile Irrlicht Engine with the latest version of mesa. And all examples run perfectly !

[sbin]

new linux new problem:

I hope someone writing back with help
under the thread "problems with 2 examples with linux" i have just read other guys
have problems too with nvidia

[dbu]

well, this output looks just as i had when trying to compile with gcc-2.95
are you shure you are using 3.3.2?
try g++ --version and see what you get

[sbin]

Well I have link to 3.22
now i can make the example.

Do you have Opengl support in your Linux ?
Which version of Linux do you use ?

[coffeefrombrazil]

Sounds like you need to install drivers for your video card. If it's a nvidia card which for me gave similar errors just go here: http://www.nvidia.com/object/linux_disp ... -4496.html

[sbin]

hey,
this is a debian 3.0 stable with i think not the real opengl support on a xbox
I have install xlibmesa3 -gl-dev, xlibmesa3 -glu-dev, xlibosmesa3 -dgb,xlibosmesa3 -dgb-dev
I can do a make
