Porting an application on Ubuntu
-
I created a widget application on Debian machine and it runs good. Now I copied the application on Ubuntu machine and opened it. While compile I get an error
cannot find -lGLESv2.
I guess some library is missing. What should I install?Another information. When I open Qt Creator I get
The following plugins have errors and cannot be loaded
QmlDesigner
QmlProfiler
Plugin initialization failed Cannot create OpenGL context.
I suppose it's related.@jenya7 said in Porting an application on Ubuntu:

I know nothing about this, but are you compiling fro RPi? Googling for
qt cannot find lGLEsv2(Note for Google search, you must omit the leading hyphen, do not put-lGLEv2in your search string, else it will avoidlGLEv2!) reveals RPI hits, do you want to read those? -

@jenya7 Install libgles2-mesa-dev package
It says - libgles2-mesa-dev is already the newest version (19.2.8-0ubuntu0-18.04.3)
@jenya7 Usually one has to install libgl1-mesa-dev on Linux like described here: https://doc.qt.io/qt-5/linux.html

can you show your exact compile error messages?

The following plugins have errors and cannot be loaded

Hi,
How did you install Qt on both these machines ?

I installed it on Ubuntu. The problem is on Ubuntu.
I have Qt installed on another machine on Debian (for RPi) and on this installation the widget application runs without problems.I found the solution. During the installation I broke the GPU driver libraries, so this helped
sudo apt install --reinstall mali-x11
