Compiler Bug about pynq-computervision

[denolf]

Hi,

Thanks for your enthusiasm on our CMake SDx build flow.

On Windows (10), we run cmake from the command line in a "SDx Terminal 2018.2" (installed under the Xilinx Design Tools) and specify to generate "Unix Makefiles"

For example:

cmake .. -G "Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=........\frameworks\cmakeModules\cmakeModulesXilinx\toolchain_sds.cmake -DSDxPlatform=X:\projects\image_processing\platforms\Ultra96\ultra_v2.3\2018.2\ultra -DSDxClockID=1 -DusePL=ON -DnoBitstream=OFF -DnoSDCardImage=ON -DSDxArch=arm64

Regards

Thank you, Kristof
I've tried your suggestions and met the following problems,

It seemed that cmake didn't find my opencv build path. So I tried:

-DOpenCV_DIR=C:\Users\chang\Anaconda3\Library\lib

and then another error:

I can not understand why cmake should find my opencv installed in anaconda, because it should not depend on anaconda. I thought it was supposed to find my xfopencv path, but there is no binary libraries in the xfopencv, only cpp and hpp. Do you have any suggestions?

[denolf]

Hi,

Can you try again but specifying an absolute path for your SDxPlatform?

Regards

Kristof

[denolf]

Closing, please open a new issue if the absolute path this not resolve this.
