Compatibility with Vitis 2020.2? about hlslib HOT 16 CLOSED

The thing is, even if the folder is somehow incorrect, it should be able to deduce the version number from the folder name, so I'm quite confused as to what is happening here. Unfortunately I can't reproduce it, so not sure how to debug.

Are you running this on Linux, or some Windows setup?

Have you tried setting your PATH to point to the folder that v++ is in instead of setting VITIS_ROOT, i.e.:

PATH=/vitis/install/Vitis/2020.2/bin cmake ..

Did you try setting XILINX_XRT to point to the installation of XRT, like the error suggests? (This is different from your Vitis installation!)

from hlslib.

Hi Kerstin -- I'm running Vitis 2020.2 myself, so it's expected to work. As far as I can see, you are invoking CMake correctly, assuming the VITIS_ROOT path is what hlslib expects.

I can't help but notice that you are passing what looks like a Windows path -- are you running this on Windows? I've never tested hlslib on Windows, and I wouldn't be surprised if there are some issues there.

As a sanity check, could you also verify that path\to\xilinx\Vitis\2020.2\bin\v++ exists?

Regarding Intel: This depends on how you are including hlslib. If you include is as a subdirectory (with CMake's add_subdirectory), then it will always look for Intel, but not fail if it's not found, so you can safely ignore this. You can also call find_package(Vitis) from your own CMakeLists.txt instead of relying on hlslib doing it.

I have similar problem as well, I'm running Vitis 2020.2.
Here is my log:

Any idea?

Great project, btw.

Hi @cothan, this looks like a different issue. Did you try explicitly passing the path to an XRT installation as suggested in the error message? You can also set the environment variable XILINX_XRT to point to your XRT installation.

You also shouldn't be getting that warning when using Vitis 2020.2. Could you do me a favor and check what Vitis_VERSION, Vitis_MAJOR_VERSION and Vitis_MINOR_VERSION are set to after running your CMake script? You can print them by adding this after line 87 in FindVitis.cmake:

message(STATUS "Version: ${Vitis_VERSION}, major: ${Vitis_MAJOR_VERSION}, minor ${Vitis_MINOR_VERSION}")

Hi @definelicht ,

It's seem like the script is not able to find the Vitis version..

As shown in the picture, I set two directory paths, and cd to the real path to make sure it's exists.

from hlslib.

wait, could it be the different from Vitis installation package ?
I have Vivado (HW developer), does it require Vitis (SW developer) to be installed as well ?

Please let me know.

i am using this in windows 10 with vivado 2020.2

from hlslib.

@madhureddyr I think the issue is backslashes in Windows file paths: https://stackoverflow.com/questions/13737370/cmake-error-invalid-escape-sequence-u/28565713

Can you see where in FindVitis.cmake this error is occurring?

from hlslib.

I changed the path from backslashes to forward slashes,I am still getting the log as:

@definelicht
please help with the issue.
Many thanks for considering my request.
Shall we connect via any medium to clear my problem...

Did you make changes to the CMake files in hlslib? The error message you got looks like you are changing the find_package macro.

from hlslib.

there are no files in hslib folder.

no, I did make changes in hslib folder.

Could you please open a new issue, and post the exact steps that you are doing to reproduce? Include the exact commands you are running to clone, configure, and compile.

Make sure to clone gemm_hls with --recursive.
