Error in simulation due to unknown generated files in Modelsim

Hi,

Somehow I got the solution by changing the order of files in the compilation. And keep the package files in the same folder where my testbench is. Below is my testbench code.

I have come across another issue. I am using 2 package files, in the first package file, I have defined multiple byte structures. And using the first package I have defined structures of the group of bytes. So my case is, from testbench I have to write individual byte as per the first package and I have to read group of byte from second package. I am able to write in frist package but I did not get it from second package. So I want to know that is it possible ? if yes then How? and If no then what I can do for that?
