My application (UVtools) does not work under fedora 35 due openCV.
I compiled the libcvextern.so, ldd show no missing dependencies, still it fails to start with the famous DllNotFoundException

Installed:
sudo yum install -y libjpeg-devel libjpeg-turbo-devel libpng-devel libgeotiff-devel libdc1394-devel ffmpeg-devel tbb-devel mesa-libGL

For opencv compilation:
sudo yum install -y cmake gcc-c++ dotnet-sdk-5.0 gtk3-devel gstreamer1-devel ffmpeg ffmpeg-devel libdc1394 libv4l-devel cmake-gui ocl-icd-devel freeglut libgeotiff libusb

here the debug on the sample console app:

How about "libdl"?

      5408:	find library=dl.so [0]; searching
      5408:	 search cache=/etc/ld.so.cache
      5408:	 search path=/lib64:/usr/lib64		(system search path)
      5408:	  trying file=/lib64/dl.so
      5408:	  trying file=/usr/lib64/dl.so
      5408:	
      5408:	find library=libdl.so [0]; searching
      5408:	 search cache=/etc/ld.so.cache
      5408:	 search path=/lib64:/usr/lib64		(system search path)
      5408:	  trying file=/lib64/libdl.so
      5408:	  trying file=/usr/lib64/libdl.so
      5408:	
      5408:	find library=dl [0]; searching
      5408:	 search cache=/etc/ld.so.cache
      5408:	 search path=/lib64:/usr/lib64		(system search path)
      5408:	  trying file=/lib64/dl
      5408:	  trying file=/usr/lib64/dl
      5408:	
      5408:	find library=libdl [0]; searching
      5408:	 search cache=/etc/ld.so.cache
      5408:	 search path=/lib64:/usr/lib64		(system search path)
      5408:	  trying file=/lib64/libdl
      5408:	  trying file=/usr/lib64/libdl

It looks like dotnet couldn't find libdl in any of the standard search path...

---> System.DllNotFoundException: Unable to load shared library 'dl' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libdl: cannot open shared object file: No such file or directory

FYI, "libdl" is used to dynamically load the unmanaged libraries.

libdl is the glibc package in fedora

[tiago@fedora ~]$ ldconfig -p | grep libdl
	libdleyna-core-1.0.so.5 (libc6,x86-64) => /lib64/libdleyna-core-1.0.so.5
	libdl.so.2 (libc6,x86-64, OS ABI: Linux 3.2.0) => /lib64/libdl.so.2

Maybe i need to make a link to /usr/lib64/libdl.so, will try that

ln -s /usr/lib64/libdl.so.2 /usr/lib64/libdl.so solved the problem.
Now the strange thing is that with ubuntu libcvextern.so it runs.
But with the lib compiled in fedora it wont run... Do i need to recompile with this new symbolic link in place?

Solution:
sudo ln -s /usr/lib64/libdl.so.2 /usr/lib64/libdl.so
