How to Compile OpenGL for ARM

SGaist

Hi,

What did fail ?

Did you get all the opengl libraries needed for arm to cross-compile Qt ?

dreamerindia

Actually i'm developing the QT in qt creator and compiling it on QT-Eclipse Integrated IDE for ARM target.
I Can Successfully compile and run the QWT widgets(http://qwt.sourceforge.net) in qt creator in x86 host.
But when i try to compile it on eclipse for arm target it gives error in GLWidget.
So i copied the QtOpenGL header files from qt sdk include folder (/home/ravivarman/qtsdk-2010.03/qt/include/) to arm target include folder (/usr/local/DigiEL-5.6/x-tools/arm-cortex_a8-linux-gnueabi/arm-cortex_a8-linux-gnueabi/sys-root/usr/include/)
I also downloaded qwt lib files (http://www.openmamba.org/distribution/distromatic.html?tag=devel-future&pkg=libqwt.arm) for ARM and pasted in target lib directory (/exports/nfsroot-ccwmx51js/usr/lib/)

When i compiled the qwt example project in Eclipse IDE i get these 4 errors.
1.'GL_TEXTURE_2D' was not declared in this scope'
2.'GLenum' has not been declared'
3.'GLuint' does not name a type'
4.'GL/gl.h: No such file or directory'

gl.h is in /usr/include directory and GL_TEXTURE_2D,GLenum & GLuint are declared in this header.so i included this path in the project.still it showing error.

kindly help.

Im totally not familiar with this, but maybe you are trying to compile the normal opengl for arm? As far as I know, arm only supports opengl Es for mobile devices/embedded systems.
But probably someone with more knowledge should be able to help you.

SGaist

You need to get the OpenGL packages for ARM not just copy your headers in your cross-compiler environment.

Also gl.h should be found in a GL sub-folder

dreamerindia

yes gl.h is in GL subfolder inside /usr/include.

But where to get OpenGL packages for ARM.

OpenGL or OpenGL-ES?

SGaist

Do you have a linux distribution for your target ?

dreamerindia

are you asking about linux distribution of opengl?

SGaist

No, about the linux distribution you are running on your board

dreamerindia

@cat /proc/version@ command gives

Linux version 2.6.31.14 (ravivarman@linux) (gcc version 4.4.3 (crosstool-NG-1.8.2) ) #3 Tue May 14 14:40:1

This doesn't really help me, what system did you install on your target ? OpenEmbedded ? Angstrom ? Debian ?

dreamerindia

Actually how to find it?

I'm using Digi Embedded Linux. I donno its distribution

pls look at the below link.

SGaist

The best is to check with Digi what exactly is provided with their system (framebuffer/DirectFB/OpenGL support etc...) then you'll be able to go further

dreamerindia

most probably debian.

because i use to run debian lib packages some time.

SGaist

Debian is one thing but what you need to know is on top of what is their Qt 4 running (linuxfb or something else)

dreamerindia

Actually our Target BSP is developed using LTIB.

dreamerindia

After reading "https://community.freescale.com/thread/261568":https://community.freescale.com/thread/261568 yea its linuxfb

SGaist

IIRC, you also have linuxfb for Qt 5
