The OpenGL ES 2.0 functionality test failed

[small_bird]

When I cross-compiled qt5.6.1 for my arm board, I got the following error:

OpenGL ES 2.0 auto-detection... ()
arm-arago-linux-gnueabi-g++ -c -pipe -O2 -Wall -W -fPIC -I. -I/home/smallbird/tslib1.4/include -I/usr/opengles2/include/GLES2 -I/usr/opengles2/include/GLES2 -I../../../mkspecs/linux-arm-gnueabi-g++ -o opengles2.o openglesp

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
/usr/qt-everywhere-opensource-src-5.6.1/qtbase/mkspecs/linux-arm-gnueabi-g++.

However, I have already designated the Include and Library path and the header files and library files are got through the way that I cross-compiled mesa-12.
Many people have came across this kind of problem ! Does anyone know the reason ?
Hope this topic can help more people !
Thanks in advance ！

@small_bird These directories are on your host PC:

-I/usr/opengles2/include/GLES2 -I/usr/opengles2/include

you need to use those from your sysroot.

[small_bird]

@jsulm I know what you mean. However, the compiler has found the headers and the libraries. Why it still tell me that I need to designate the path variables ?

[jsulm]

@small_bird The actual issue is this:

arm-arago-linux-gnueabi-g++: error trying to exec 'cc1plus': execvp: No such file or directory
as: unrecognized option '-mfloat-abi=softfp'

I don't know why this happens.
arm-arago-linux-gnueabi-g++: error trying to exec 'cc1plus': execvp: No such file or directory - looks like the C++ compiler is not found.
as: unrecognized option '-mfloat-abi=softfp' - looks like the wrong assembler (x86) is called.

Is your build environment broken? How do you call configure?

[small_bird]

@jsulm

#!/bin/sh
./configure
-v
-prefix /home/smallbird/qt5.6.1
-release
-continue
-confirm-license
-plugin-sql-sqlite
-qt-libjpeg
-qt-libpng
-qt-zlib
-opengl es2
-no-c++11
-qpa xcb
-qt-xcb
-opensource
-xplatform linux-arm-gnueabi-g++
-force-pkg-config
-make examples
-no-dbus
-pkg-config
-qt-freetype
-qt-pcre
-I/home/smallbird/tslib1.4/include
-L/home/smallbird/tslib1.4/lib
exit

This is my configuration.

@small_bird said in The OpenGL ES 2.0 functionality test failed:

-sysroot /

"-sysroot /"? So, your host PC file-system is your sysroot? This is for sure not going to work.

[small_bird]

@jsulm Sorry for that, I have corrected it.

[small_bird]

@jsulm
But you really remind me of some method.
There is some option that could change the configuration: -mfloat-abi=softfp.

[small_bird]

@jsulm
But you really remind me of some method.
There is some option that could change the configuration: -mfloat-abi=softfp.
It is -qreal option. However, it can only change the qreal type.
Then how to solve the problem ?

[jsulm]

@small_bird The first problem to solve is:

arm-arago-linux-gnueabi-g++: error trying to exec 'cc1plus': execvp: No such file or directory

It looks like something is wrong with your build environment. Are you able to build a simple C++ program with this environment?

[small_bird]

@jsulm No, I can not build c++ program. The error is the same !

[jsulm]

@small_bird Then I would say your build environment (compiler) is broken.

[small_bird]

@jsulm Yes, I am checking for that. However, gcc compiler is all right.
