UVM1.2 with modelsim 2021.4

[chirowuvm]

I tried to run an example from EDA playground https://www.edaplayground.com/x/296 with modelsim 2021.4 and run into the following errors

# ** Fatal: (vsim-160) C:/Projects/uvm_1_2/src//dpi/uvm_svcmd_dpi.svh(27): Null foreign function pointer encountered when calling 'uvm_dpi_get_next_arg_c'

I am not sure how to approach this problem

It looks like you didn't compile the DPI portion of the UVM library, or don't know how to use the pre-compiled versions of the UVM library. (I don't know if Modelsim has pre-compiled libraries; Questa does for sure)
