Hello,
I am trying to preprocess a mesh in CGNS format to generate a 'mesh_input'
But it comes out such error:

Could anyone teach me how to solve this problem?

Problem solved:

if you set disable_frontend =yes when installing using install_saturne.py ( automated installs )

~/.../libexec/cs_proprocess will not be installed

This is why the error "No such file..." occurs
