Hi,

This is strange: you specified ``-DCMAKE_INSTALL_PREFIX`` as being ``/home/abolfazl/prog/nest-install``, but nest-config reports the prefix as ``/usr``. It might be that you have two installations next to each other, one in each directory. Could you clean all build files in all directories (and any package manager NEST installations that might be present), and double-check the paths reported during the cmake configuration stage, to make sure they are consistent?

Regards,

Charl

Dear Charl,

Could you please post the output of:
nest-config --prefix
/usr
nest-config --datadir
share/nest

I reinstalled the nest package and made sure there is no space in directory names.
cmake -Dwith-python=3 -DCMAKE_INSTALL_PREFIX:PATH=/home/abolfazl/prog/nest-install /home/abolfazl/prog/nest-source

regards,
Abolfazl
