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 ?

Yes, I checked libs and header path in configiration

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

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
