Hello Antonio,
there are different types oft he same xilinxcorelib, one for Linux-64 bit, one for Linux-32 bit and one for Windows.
What I do not know what the difference is between xst and hdp. But you can try-out this.
You have to select the library according to your OS. Cope your library to your notebook.
How to link in Questa:
In the Questa GUI select File → New → Library. Then an window opens. Choose ‘a map to an existing library’. Library Name: xilinxcorelib; Library maps to: choose the corresponding path where you stored the xilinxcorelib.
Then you can start to compile.
Good Luck
Christoph
