Question on error message: "The compiled entry-point 'FIFO_Buffer_hdl_mex' cannot be located."

I was trying out this example and I noticed testbench generation failed due to the following message:

https://www.mathworks.com/help/hdlverifier/ug/generate-fifo-interface-dpi-component-for-uart-receiver.html

>> cd(setupExample('hdlverifier/GenerateFIFOInterfaceDPIComponentForUARTReceiverExample'))

>> design='FIFO_Buffer';

>> testbench='FIFO_Buffer_tb';

>> FIFO_Buffer_tb

Warning: MATLAB has disabled some advanced graphics rendering features by switching to software OpenGL. For more information, click

>> dpigen -testbench FIFO_Buffer_tb FIFO_Buffer -args {0,int8(0),0}

Error using dpigenerator_generateTestBench

Unable to generate testbench for SystemVerilog DPI component. Please refer to the examples for guidelines on how to write the MATLAB

testbench.

Error in dpigen

Caused by:

Error using coder.internal.Float2FixedConverter

Error using coder.internal.Float2FixedConverter

The compiled entry-point 'FIFO_Buffer_hdl_mex' cannot be located.

Is there any particular reason why this occurs? And how should this be fixed? (I was running matlab from a linux machine)

Hey Yufei,

It seems like you misunderstood the way in which you need to use the commands from the mentioned documentation page.

>> design='FIFO_Buffer';
>> testbench='FIFO_Buffer_tb';

When you execute the above mentioned commands on the MATLAB command line, it will simply create two string objects in the workspace. Instead of this, the documenation states that you need to execute the follwoing commands to open the 'FIFO_Buffer.m' and 'FIFO_Buffer_tb.m' files.

>> edit('FIFO_Buffer')
>> edit('FIFO_Buffer_tb')

I used these commands and did not eccounter any error. I am attaching a screenshot of the same for your reference.
