Install issues about openvino HOT 8 CLOSED

can you show the full cmake generation text? I can not see any error before the configuring incomplete.

I have solved my issue, thank you. @SeverineH
But I have another question about these demos just run with python3?

from openvino.

When I cmake, there is a error about:

Determining if the pthread_create exist failed with the following output:

And there is not setupvars.sh in the folder of <../inference-engine/bin>, so I could not set the environment variable.

@wanghanyang123 , yes demos run with Python3. If I understand correctly you solved issue and can I close this issue?

How did you solve this

from openvino.

@wanghanyang123 I confused how you solve the problem?

from openvino.

Hi, can anyone give some information on how to resolve the cmake failed with check "pthread" error?

I built openvino on Ubuntu 19.10

/usr/bin/cmake -E cmake_link_script CMakeFiles/cmTC_fa979.dir/link.txt --verbose=1
/usr/bin/cc CMakeFiles/cmTC_fa979.dir/CheckSymbolExists.c.o -o cmTC_fa979
/usr/bin/ld: CMakeFiles/cmTC_fa979.dir/CheckSymbolExists.c.o: in function main': CheckSymbolExists.c:(.text+0x1f): undefined reference to pthread_create'
collect2: error: ld returned 1 exit status

Closing, feel free to start a new issue if additional assistance is needed.
