Can't build chip example - /usr/bin/ld: cannot find -lGL

Hi,
Might be a silly question but are you sure you are building your application in 64bit ?

Hi @SGaist, thanks for the reply first.
I don't think your question is silly - I was also thinking about that when I saw the paths where ld was searching the lib, but ...
I uninstalled NVIDIA driver, screen resolution on my notebook is ugly now, but chip example is compiled and linked without any errors! And when I run the chip example OpenGL is supported!
As far as I understand, installation of NVIDIA video card driver breaks ... something in ... somewhere :) But I have no idea what and where, and how to fix it :(
Maybe you know the way how to tell Qt to use NVIDIA driver, or OpenGL lib, or ... something to fix the problem?
Thanks in advance for answering. -
How did you install the Nvidia stuff ?
-
What about the associated OpenGL libraries ?

Here are the libs:
[user@centos-7 ~]$ ls -h /usr/lib64/ | grep "libGL" libGLdispatch.so.0 libGLESv1_CM_nvidia.so.1 libGLESv1_CM_nvidia.so.390.59 libGLESv1_CM.so libGLESv1_CM.so.1 libGLESv1_CM.so.1.2.0 libGLESv2_nvidia.so.2 libGLESv2_nvidia.so.390.59 libGLESv2.so libGLESv2.so.2 libGLESv2.so.2.1.0 libGL.la libGL.so libGL.so.1 libGL.so.1.7.0 libGLU.so libGLU.so.1 libGLU.so.1.3.1 libGLX_indirect.so.0 libGLX_nvidia.so.0 libGLX_nvidia.so.390.59 libGLX.so libGLX.so.0Do you mean anything else?

How did you instal them ?

The problem is solved - I install NVIDIA the latest driver (version: 390.67 release Date: 2018.6.5) in this way: http://www.advancedclustering.com/act_kb/installing-nvidia-drivers-rhel-centos-7/.

I download shell script from NVIDIA and started it in terminal.
