Make error in capture.cpp Ubuntu 20.04

[hoetzgit]

The following error occurs when compiling the actual release under Ubuntu 20.04. Can this be corrected? I use a powerful virtual machine to create startrail, keogram and video. Many thanks

pi@allsky:~/allsky01$ make -C src all

Hi @hoetzgit ... Sorry for the issue... Would you be able to test the following tweak and see if the compile succeeds:

cd ~/allsky
sed -i -e 's/cvGetTickCount/cv::getTickCount/g' src/capture.cpp
make -C src all

Thanks!

Thanks very much! With this adjustment, it works.

`pi@allsky:~/allsky01$ sed -i -e 's/cvGetTickCount/cv::getTickCount/g' src/capture.cpp

pi@allsky:~/allsky01$ make -C src all

Great to hear this resolved the compile issue. We've modified our code to include this fix. Thanks for helping us make Allsky better!

@hoetzgit, you can grab the updated src/capture.cpp which includes the fix. Or not, since you already patched your file.
