ERROR: Feature 'opengles2' was enabled, but the pre-condition 'config.win32 || (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed.

[MAKK]

Trying to compile qt 5.9 for my raspberry pi 3 compute module and I have been following mainly the online guide here (http://wiki.qt.io/Raspberry_Pi_Beginners_Guide). So, I have set the pi system roots to the mount point /mnt/pi-rootfs.
Please note I m using Raspbian Stretch.

The qtbase configuration was called with the following argument:
./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi

This configures qt but no openGL and I have the message:
ERROR: Feature 'opengles2' was enabled, but the pre-condition 'config.win32 || (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed.

ERROR: The OpenGL functionality tests 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 the mkspec for your platform.

In addition, I also tried to add these 'QMAKE_INCDIR_OPENGL QMAKE_INCDIR_OPENGL QMAKE_INCDIR_OPENGL' to qmake.conf in linux-rasp-pi-g++ but still no sucess.

Please advise how to fix these issues.

@MAKK Add -v parameter to configure call and see what exactly is wrong with opengles2

[MAKK]

@jsulm please find he below link containing logs.

@MAKK You're missing the libs:

> /home/minhaj/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/4.7.2/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lGLESv2
> /home/minhaj/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/4.7.2/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lEGL

[MAKK]

@jsulm how can I fix it and get these libs... please advise em newbie..

[jsulm]

@MAKK Well, you need these libs in your sysroot: /mnt/rasp-pi-rootfs. If your sysroot is a copy of the RaspPi root file system then install the libs there (apt-get on RaspPi).

[MAKK]

@jsulm This means I have to put raspbian-stretch.img to SDCard & update it. After that convert it back to image & mount it... Then run again configure command...

[jsulm]

@MAKK Or just put the SDCard into your laptop/PC after updating :-)

I had this same error and in my particular case it was due to undefined references in GL libraries:
