Problem to get OpenGL support with Qt 5.3.2 embedded

MorganeJ

Hi,

I'm having some problems with Qt and OpenGL.
I am not able to compile Qt 5.3.2 with the OpenGL support flag. I'm having a "All the OpenGL functionality tests failed!".

I'm on a Virtual Machine with Ubuntu 14.04 LTS 64bit.

Here is my configure command:
@./configure -prefix /usr/local/qt-embedded-5.3.2 -xplatform linux-arm-gnueabi-g++ -opensource -device-option CROSS_COMPILE=/opt/gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux/bin/arm-linux-gnueabihf-gcc -no-largefile -v -opengl -confirm-license@

And here the errors related to OpenGL:
@OpenGL auto-detection... ()
arm-linux-gnueabihf-g++ -c -pipe -O2 -Wall -W -fPIE -I../../../mkspecs/linux-arm-gnueabi-g++ -I. -I/usr/include/GL -o opengldesktop.o opengldesktop.cpp
opengldesktop.cpp:45:19: fatal error: GL/gl.h: No such file or directory

You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL in
/home/myuser/Downloads/qt-everywhere-opensource-src-5.3.2/qtbase/mkspecs/linux-arm-gnueabi-g++.

Here my qmake.config file:
@#

qmake configuration for building with arm-linux-gnueabihf-g++

MAKEFILE_GENERATOR = UNIX
CONFIG += incremental
QMAKE_INCREMENTAL_STYLE = sublib

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

#include openGL libraries
QMAKE_INCDIR_OPENGL = /usr/arm-linux-gnueabihf/include/GL
QMAKE_LIBDIR_OPENGL = /usr/arm-linux-gnueabihf/lib
QMAKE_LIBS_OPENGL = -lGLU -lGL
QMAKE_LIBDIR_X11 = /usr/arm-linux-gnueabihf/lib

modifications to g++.conf

QMAKE_CC = arm-linux-gnueabihf-gcc
QMAKE_CXX = arm-linux-gnueabihf-g++
QMAKE_LINK = arm-linux-gnueabihf-g++
QMAKE_LINK_SHLIB = arm-linux-gnueabihf-g++

modifications to linux.conf

QMAKE_AR = arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabihf-objcopy
QMAKE_NM = arm-linux-gnueabihf-nm -P
QMAKE_STRIP = arm-linux-gnueabihf-strip
load(qt_config)@

Inside my /usr/arm-linux-gnueabihf/include/GL, I have the gl.h file.

I tried without the flag -opengl but Qt does not recognize the QT += opengl getting this error "Project ERROR: Unknown module(s) in QT: opengl" on Qt Creator.

I also tried using :
@QMAKE_INCDIR_OPENGL = /usr/include/GL
QMAKE_LIBDIR_OPENGL = /usr/lib
QMAKE_LIBS_OPENGL = /usr/lib@

What am I doing wrong ? What am I missing ?
I tried a lot of things but I never get it work and I was not able to find an answer to this kind of question on internet.

Thank you for your help.

Did you try to add the path inside the .pro file on the follwoing way?

@
INCLUDEPATH += /usr/arm-linux-gnueabihf/include/GL

Hi,

Thank you for your help! I added this INCLUDEPATH to my opengldesktop.pro and it is compiling now.
I needed to copy some libraries from my target system into my host system but your solution is working!

Thank you a lot!

@MorganeJ
You have this in your Qmake.conf file:

QMAKE_INCDIR_OPENGL = /usr/arm-linux-gnueabihf/include/GL
QMAKE_LIBDIR_OPENGL = /usr/arm-linux-gnueabihf/lib
QMAKE_LIBS_OPENGL = -lGLU -lGL
QMAKE_LIBDIR_X11 = /usr/arm-linux-gnueabihf/lib

Where did you get these files? What are they? I am having some issues compiling myself, and dont really understand that part.

@MorganeJ Hi, I wonder how you can cross compile qt5 using a desktop-opengl? Should it be opengl es2? Cound the opengl edition you compiled work well on your embedded board? Thanks in advance!
