Ubuntu 22.04.1 LTS SDL2 wl_proxy_marshal_flags error

I'm a beginner at using Linux, so I'm following a couple of forum threads I've read so far.
I'm trying to compile a C++ program using g++ version 11.3.1, where I have installed SDL2 using the command sudo apt-get install libsdl2-dev and am using the recommended proprietary driver nvidia-driver-525 for my nvidia gtx 1060 graphics card. When I echo $XDG_SESSION_TYPE, it says x11.
However, when I compile the program using the link arguments -lSDL2, it gives me the following compile error:
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/11/../../../x86_64-linux-gnu/libSDL2.so: undefined reference to `wl_proxy_marshal_flags'
collect2: error: ld returned 1 exit status
When I compile the program with the link arguments: -lSDL2 -lwayland-egl -lwayland-client -lwayland-cursor, it compiles successfully. But then when I try to run the program, it gives me this error:
./bin/main.exe: symbol lookup error: /usr/lib/x86_64-linux-gnu/libdecor-0.so.0: undefined symbol: wl_proxy_marshal_flags

I'm in Ubuntu 20.04 using Opencv 4.4.0 in C++. I can run the file but failure throwing the next message:

I don't know what's the problem

How to compile SNAP c++ source code without getting architecture error?

I want to compile SNAP (Stanford Network Analysis Project) c++ source code using terminal on mac by running the make all command and I'm getting the following error:
ld: symbol(s) not found for architecture x86_64
Initially I was getting this error:
clang: error: unsupported option '-fopenmp'
but I found that I should replace the g++ in the Makefile.config with gcc-10 which I installed using the homebrew and now I'm getting the architecture error!
I'm on mac os Big Sur 11.0.1 and everything is up to date! Does anyone have any clue?
clang error

libGL does exists, but linker can't find it - Qt 4.8.7, CentOS 7.5

I have CentOS Linux release 7.5.1804 with Qt 4.8.7 installed from base repo. I installed NVidia driver version 390.59 release date 2018.5.16.
I have libGL-mesa and libGL-mesa-devel INSTALLED also.
My graphics card Quadro K4000M is doing just fine - for example, glxgears 60fps, Qt Demos (OpenGL) work.
But when I am trying to compile the chip example, I am getting the following error:
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../libGL.so when searching for -lGL
/usr/bin/ld: skipping incompatible //lib/libGL.so when searching for -lGL
/usr/bin/ld: skipping incompatible //usr/lib/libGL.so when searching for -lGL
/usr/bin/ld: cannot find -lGL
collect2: error: ld returned 1 exit status
make: *** [chip] Error 1
Here is the ls command output:

How to solve the problem?
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/.

Qt on Centos 7 with OpenGl not working

I have installed Qt on a CentOS 7 machine following the recommendation of QT documentation:
sudo yum groupinstall "C Development Tools and Libraries"
sudo yum install mesa-libGL-devel
a real nightmare as "C Development Tools and Libraries" does not exist. I have found and installed "Development Tools": manually as the groupinstall does not work!
I managed to run Qt creator but whenever I try to build and run any C++ application I got a cascade of errors:
:-1: error: skipping incompatible
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../libGL.so when
searching for -lGL
:-1: error: skipping incompatible /lib/libGL.so when searching for
-lGL
:-1: error: skipping incompatible /usr/lib/libGL.so when searching for
-lGL
:-1: error: cannot find -lGL
:-1: error: collect2: error: ld returned 1 exit status
I need to run the OpenGl library as my application requires the use of the Three libraries. Did anybody successfully installed Qt and OpenGL on a CentOS 7 operating system?
Install the devtoolsets-6 package and make sure you start qtcreator from a shell where you have enabeled devtoolsets 6. Then you'll have a modern dev environment. Also make sure you have installed the NVidia drivers (or AMD equivalents) for proper OpenGL support.
