Qt embedded compile with opengl error...

[minamiman]

Hi everyone
Now I'm meet some error in compiling qt embedded with opengl for arm in ubuntu 12.04 .
acturally, I am compileing qt opensource both version is 4.8.4 and 4.6.2.
I received opengl lib and header file from cpu vendor for arm.
but, in configure, I meet error message like below...

=================== configure message 4.8.4 =============================
The OpenGL ES 2.0 functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL in

my configure is

./configure -opensource -confirm-license -release -embedded arm --prefix=/project/qte-opengl -static -little-endian -no-accessibility -shared -no-cups -no-stl -qt-libpng -qt-libjpeg -no-qvfb -no-dbus -qt-freetype -no-nis -no-qt3support -no-largefile -no-libmng -qt-mouse-tslib -I/home/tslib-master/arm_tslib/include -L/home/tslib-master/arm_tslib/lib -opengl es2 -I/home/mali_drv -L/home/mali_drv -no-separate-debug-info -nomake examples -nomake docs -nomake tools -depths 16,18,24 -optimized-qmake -pch -qt-libjpeg -qt-zlib -no-libtiff -ptmalloc -no-webkit -no-script -no-scripttools -xplatform qws/linux-arm-g++

I checked there is the library and header file in /home/mali_drv folder...

mkspecs/qws/linux-arm-g++/qmake.conf is

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

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

modifications to g++.conf

QMAKE_CC = arm-none-linux-gnueabi-gcc
QMAKE_CXX = arm-none-linux-gnueabi-g++
QMAKE_LINK = arm-none-linux-gnueabi-g++
QMAKE_LINK_SHLIB = arm-none-linux-gnueabi-g++

modifications to linux.conf

QMAKE_AR = arm-none-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = arm-none-linux-gnueabi-objcopy
QMAKE_STRIP = arm-none-linux-gnueabi-strip

QMAKE_LFLAGS += -Wl,-rpath-link=/home/tslib-master/arm_tslib/lib

#QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL

load(qt_config)

Actually I was googling over 3 days but I can not find solution about this...
please advise to me.

Best Regards

Hi and welcome to devnet,

Did you ensure that the libs and header were put in a folder that can be found by the configuration script ?

[minamiman]

Yes, I checked libs and header path in configiration

[SGaist]

Can you re-run configure with -v ? That should show you where the failure happens

[minamiman]

thans you for your apply...
when i was doing with -v option,
error message is below...

Did you install the ARM headers/libs in your system folders ?

Hello SGaist,

I am also getting the below error, while configuring Qt with opengl -es2 option. Can you please elaborate, how to install ARM headers/libs in system folders ?

Error:
opengles2.cpp:45: fatal error: GLES2/gl2.h: No such file or directory

Thanks,
Sachin

Installing ARM headers/libs in system folders is wrong.

You have a tool chain with it's own set of headers and libraries. Copy then needed files there. (You can get them i.e from the debian packages)

Hi,

I am having problem in providing finding the lib -lGLESv2 in the downloaded packages. But there is a lib -lGLESv2x present in the package. But, the configuration is searching for -lGLESv2.

How do I solve this issue ?

Note: I am using Red-hat Linux.

Thanks,
Sachin

From the debian packages: "libgles2-mesa-dev" and its friends
