OpenGL ES 2.x disabled.
-
Hello,
I tried to configure Qt5 using this command
./configure v -opensource -confirm-license -no-pch -no-xcb -no-opengl -opengl es2 -make libs -device imx6 -compile-examples -device-option CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi -sysroot /ltib_install/ltib/rootfs -no-gcc-sysroot -prefix /opt/qt5
I am getting below error..
opengles2.cpp:45:25: fatal error: GLES2/gl2.h: No such file or directory
compilation terminated.
make: *** [opengles2.o] Error 1
OpenGL ES 2.x disabled.
The OpenGL ES 2.0 functionality test failed! You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in /home/jigar/qt5/qtbase/mkspecs/devices/linux-imx6-g++. -
OpenGL is required by QtGui and QtQuick modules: you can't compile them without it. You can skip unneeded modules with
@
-skip modulename

Hello Sierdzio,
i am new in QT and also in Ubuntu.
I don't get it how can i skip modules? -
my qmake.conf file is like this..
qmake configuration for the Freescale iMX6 boards (single, dual and quad)
This mkspec is based and tested on the ltib-source-release 3.0.15
Building ltib including glib, gpu-drivers and what ever you want to use (e.g. dbus or fontconfig)
This mkspec is tested with a framebuffer (eglfs) configuration (not testes with X11)
A typical configure line looks like:
/home/tsenyk/qt5/qt5/configure -opensource -confirm-license -make libs -device imx6 \
-device-option CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- \
-sysroot <path-to-your-ltib-install>/rootfs -no-gcc-sysroot \
-prefix /usr/local/Qt-5.0.0/Qt5-imx6-1
NOTE: currently ltib doesn't produce a proper staging/sysroot-filessystem.
If gcc's --sysroot is used, the toolchain doesn't find basic binaries (e.g. crt1.o),
therefore you have to pass -no-gcc-sysroot to configure if you pass -sysroot to configure!

OK, in this case I think you can safely just omit that "-no-opengl" flag when calling configure. The board seems to have all you need to run OpenGL ES.

I tried this below script. and it works ..
so can you tell me will i get any problem related to gui of QT?./configure -v -opensource -confirm-license -no-pch -no-xcb -no-opengl -make libs -device imx6 -compile-examples -device-option CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- -sysroot /home/jigar/ltib_install/ltib/rootfs -no-gcc-sysroot -prefix /opt/qt5

I don't understand this question, please rephrase or explain.
If it compiles, the situation is definitely looking good. Without OpenGL, you should be able to use all non-gui modules (core, network, XML, etc.), plus QtQuick1 and QtWidgets.
-
but i need qtqui module also..
so now i must have configure with opengles2.0.
so now how can i add opengles2.0 in my sysroot?
i am using ltib as rootfs and in ltib opengles is not available. -
QtGui itself is kind of a hard question: it does not depend on OpenGL as such, but might be required in some situations. You have said that the configuration and make stages were successful, so I think it is fine.

I am following below link to cross compile qt 5.
https://community.freescale.com/docs/DOC-94066But on step 8 i have a problem again because now i don’t have a “qtjsbackend” directory in my installed qt5 directory. :(
-
Do you want to use QtQuick1 (a deprecated module)? If no, then just skip it.
-
okay... but i realize now that i must need qtQuick2 as i am developing gui and for that i must need opengles2...
-
okay... but i realize now that i must need qtQuick2 as i am developing gui and for that i must need opengles2... so now i know that i can not condigure without opengles 2.0..
-
You can choose to use widgets, which should not require OpenGL. But QtQuick 2 is cool, too :) Your board does support it, so no worries.
-
hie again back after long time..
as you suggested me to compile without gles 2.0 .. i did that and it was perfect..
i am following this link to cross compile qt 5.2.
https://community.freescale.com/docs/DOC-94066now in step 8 as described there should be 2 directories.
qtjsbackend and qtdeclarativebecause when i configure qt i used no opengles . so i am not getting qtjsbackend. that's fine. i am getting qtdeclarative directory.
When i tried to build that directory using ../qtbase/bin/qmake -r command.
I got error for qt-quick.
Project ERROR: Unknown module(s) in QT: quick-privateTo solve this error i tried following solution
modify this file qtbase/bin/qt.conf and add the correct prefix, the one given on configure
[EffectivePaths]
Prefix=/opt/qt5But still i got same error.
Thanks you.. :) -
Some people say that this can be fixed by turning off tests and examples:
@
-nomake tests -nomake examples
@ -
but whre should i write because i write this at configuration time and i got error like this...

I have not seen that error before, and I am using this flag regularly. Possibly some other option is silently removing tests already, although that would be a bit strange. Remove the flag, then.
-
so now how should i go ahead? any idea?
