Modelsim Error: (vcom-11) Could not find altera.maxplus2

Hello all,

I am completely new to vhdl, altera and modelsim so please bear with me if the question is too simple. I have tried to scout the web for any leads - but so far without any real progress.

I have created a simple structural design based on 74xxx components from the altera maxplus2 library (altera\13.0\quartus\libraries\vhdl\altera). I know this can be done as behavioral - but I am transferring an old TTL design that I want to verify.

I have included in my vhdl file:

LIBRARY altera;

USE altera.maxplus2.ALL;

Following setp by step the "getting started wtih quartus ii simulation using the modelsim-altera software" guide to open up modelsim with nativelink I get the following error message in the transcript window:

# ** Error: (vcom-11) Could not find altera.maxplus2.

And from this point I cannot progress. I have tried to compile the maxplus2 library with the modelsim compile functionality - but in all honesty I am not really sure what I am doing. I get a maxplus2 folder in RTL-WORK directory - but it doesnt help at all as I get the same error when I re-execute the "do"-command line.

Any pointers as to where I can look for further reading on this topic or any advice to resolve this is highly appreciated.
