Instantiation Components Compile error

Hi,

I've finally got it. I had to use specifically a use clause of the comp_pkg.vhd (component packaging) in the main Top Level vhd file, but not necessarily the parts_lib.vhd file which contains the entity-architecture parts units. It seems that we have to use a use clause in the main file when a file to be included contains a package definition. The latter apparently cannot be read and compiled when inserted in the project file section.

Thanks again for trying to help.

PS : I just don't know then what's the use of the user library file if nothing happens when the libraries are inserted there.
