Co-Simulation error while running after successful synthesis about vitis_libraries HOT 8 OPEN

Hello @wilfredkisku ,

This seems to be a known issues in older tool versions. Please try the solution mentioned in the below link to overcome the issue:

from vitis_libraries.

@vt-lib-support Thank you for the reply. I forgot to mention that I am using OpenCV 3.3.1.

Also, I tried including the library header as you mentioned (in the testbench cpp file) but I am still getting the error related to gmp.

from vitis_libraries.

What OS are you running?

Please try adding it here:
https://github.com/Xilinx/Vitis_Libraries/blob/2020.2/vision/L1/include/common/xf_headers.hpp#L27

#include <gmp.h> 
#define __gmp_const const

from vitis_libraries.

I tried it both on Ubuntu 18.04 LTS and 20.04 LTS.

Is there an issue with the OpenCV version according to you? I also might be making a mistake in defining the include, lib and flags paths in the settings.

from vitis_libraries.

OpenCV version shouldn't cause this error. From the log you posted, the paths and flags look fine.
You may try adding the below lines:

#include <gmp.h> 
#define __gmp_const const

at this line : https://github.com/Xilinx/Vitis_Libraries/blob/2020.2/vision/L1/include/common/xf_headers.hpp#L27 to see if it fixes the error.

Are you getting this error in CSIM too?

from vitis_libraries.

Yes, I am able to run synthesis without any errors (just warning messages). The above-mentioned issues come only after I try to run CSIM (co-simulation).

I will try the above-mentioned fix by adding it to the xf_header.hpp and post the progress. Thank you once again.

from vitis_libraries.

@vt-lib-support Thank you for the help. It works now, I am able to carry out both synthesis and csim.

While exporting the Vivado IP, I get this error though.

This seems to be an issue caused by y2k22 bug in Vitis/Vivado older versions. Please follow the steps mentioned here and see if it gets resolved:
