Error when running make about pynq-computervision

[denolf]

Hi Amir,

Can you provide us some more details so that we can reproduce your issue?

• Xilinx tool version
• CMake command and output

Thanks

Kristof

HI Amir,

Thanks for this extra information. It looks like the wrong sysroot is being picked up, instead of the one from the Ultra96 bare platform package. CMake is trying to find
sw/sysroot as subfolder in your SDxPlatform (in your case -DSDxPlatform=/work/SDxPlatforms/ultra).
Can you confirm you indeed have a folder /work/SDxPlatforms/ultra/sw/sysroot on your system?

Regards

Kristof

[amirkiperwas]

Hi Kristof,
I indeed have that folder:

ls -lt /work/SDxPlatforms/ultra
total 12
drwxrwxr-x 2 amirki amirki 4096 Dec 17 22:58 hw
drwxrwxr-x 4 amirki amirki 4096 Dec 12 19:28 sw
-rw-rw-r-- 1 amirki amirki 575 Dec 12 18:50 ultra.xpfm

and

Hi Amir,

That indeed seems OK. Can you try forcing the sysroot path using the SDxSysroot variable, so your cmake command would become something like:

cmake .. -DCMAKE_TOOLCHAIN_FILE=../../../frameworks/cmakeModules/toolchain_sdx2018.2.cmake -DSDxPlatform=/work/SDxPlatforms/ultra/ -DSDxSysroot=/work/SDxPlatforms/ultra/sw/sysroot -DSDxClockID=1 -DusePL=ON -DnoBitstream=OFF -DnoSDCardImage=ON -DSDxArch=arm64

Then reply with the CMake output.

Thanks

Kristof

This helps and the C objects are built. I now get a different error:

Hi Amir,

It looks like the platform you have is somehow not correct which is causing the compilation errors. Can you try making sure you downloaded the correct 2018.2 ultra96 platform as described in https://github.com/Xilinx/PYNQ-ComputerVision/blob/master/overlays/README.md? The file can be found at https://www.xilinx.com/member/forms/download/xef.html?filename=ultra96_platform_sysroot_2018.2.tar.gz. The correct platform should have opencv v3.2 files such as ultra/sw/sysroot/usr/lib/aarch64-linux-gnu/libopencv_core.3.2.

Hi Jack,
I did as instructed in the README.md file.
Just to make sure I downloaded the ultra96 platform files again from your link.

I got the same Errors as I posted before.

[jackl-xilinx]

Hi Amir,

It looks like the cmake script is unable to find the OpenCV files inside the sysroot. The fact that you were unable to find ${SDxPlatform}/sw/sysroot and needed to define ${SDxSysroot} was an early indication something is not working right. Subsequently, it doesn't set the proper ${OpenCV_DIR} from within the toolchain_sdx2018.2.cmake script which points to the opencv inside sysroot.

What version of cmake are you running? If you have the xilinx tools installed, it should use the cmake under /opt/Xilinx/SDK/2018.2/tps/lnx64/cmake-3.3.2/bin/cmake.

Are you able to see the file /work/SDxPlatforms/ultra/sw/sysroot/usr/include/stdlib.h?

If the above two conditions are correct, then line #134 of toolchain_sdx2018.2.cmake should find the platform sysroot. If not, there's something else not working properly in your setup.

Hi Jack,
which cmake returns:

which cmake
/opt/Xilinx/SDK/2018.2/tps/lnx64/cmake-3.3.2/bin/cmake

and

ls -lt /work/SDxPlatforms/ultra/sw/sysroot/usr/include/stdlib.h
-rw-rw-r-- 1 amirki amirki 35784 Oct 17 23:56 /work/SDxPlatforms/ultra/sw/sysroot/usr/include/stdlib.h

I went over the instructions and did everything from the beginning (making sure I have the correct commits checked out) and the make passes.

Thank you!

Closing issue since CMake and make now pass for Amir.
