I installed everything according to the instructions

First, I don't recommend to run it under root.
Second, you cannot run cpp file, you need to compile everything first.

[teo2022]

I followed these commands! still the same (do you need to do something else?

cd vlfeat
make

cd ../build
cmake ..
make

[teo2022]

root@80-78-247-58:/var/www/html/mods/build# cmake ..

OK, then you should go into build directory and run the compiled file, not .cpp

./mods examples/cat.png examples/cat2.png out1.png out2.png k1.txt k2.txt m.txt l.txt 0 0 examples/cat.txt config_iter_mods_cviu.ini iters_mods_cviu.ini

[teo2022]

-bash: ./mods: No such file or directory

[ducha-aiki]

Then you haven't compiled it (I don't see logs from running make command), or you are not in the correct directory

[teo2022]

[ducha-aiki]

Of course, there is no mods file, there is "fatal error".
Another hint: when you run cmake command, it didn't find OpenCV.
So, please, install OpenCV first.

can't install this package, already tried different options

[teo2022]

ubuntu 20.04

[teo2022]

sudo apt install python3-opencv - installed this package

[ducha-aiki]

The instructions are for ubuntu 14.04, which is stated in the readme.
Sorry, but I cannot guide you on how to install OpenCV on modern Ubuntu, there are enough resources on the web on it, and also C++ development is tricky and might be time-consuming.

i installed it, here is the screen
