cant make a core work - Githubissues

My attempt to make my own STELLA (atari) core changes I got in trouble running the compiled core. Read more below:

When I fetch and compile the STELLA core it works fine when I run retroarch -v -L /home/unknown/snap/retroarch/1005/.config/retroarch/cores/stella_libretro.so /home/unknown/Downloads/Atari\ 2600/Enduro.bin

However, if I just copy the libretro-super/libretro-stella folder and paste in libretro-super/libretro-clonedstella then run NOCLEAN=1 ./libretro-build.sh clonedstella. The compiler runs fine (except for the final cp:

cp "clonedstella_libretro.so" "/var/www/html/libretro-compile/libretro-super/dist/unix/clonedstella_libretro.so"
cp: cannot stat 'clonedstella_libretro.so': No such file or directory

But the file was compiled successfully at libretro-super/libretro-clonedstella/stella NOTE: I did not changed any file from the copied directory, which I suppose it should work as expected.

This is fine, this is not the problem. The problem is that for some reason, the file libretro-super/libretro-clonedstella/stella cannot be used as a retroarch core:

cp ./libretro-super/libretro-clonedstella/stella /home/unknown/snap/retroarch/1005/.config/retroarch/cores/clonedstella_libretro.so;
retroarch -v -L /home/unknown/snap/retroarch/1005/.config/retroarch/cores/clonedstella_libretro.so /home/unknown/Downloads/Atari\ 2600/Enduro.bin

This outputs the following:

I dont know how to get more debugging info than that and I have no clue about whats the problem. What cannot dynamically load position-independent mean?

PS: compiling under ubuntu 20

libretro / libretro-super
