Description Jack 2021-05-03 22:26:07 UTC
I'll attach full build log, but 

src/image/videoformat.cpp:289:19: error: 'numeric_limits' is not a member of 'std'

Reproducible: Always

Steps to Reproduce:
1. emerge webcamoid
Actual Results:  
listed error

Expected Results:  
successful emerge

adding one line to the file with the error allows successful emerge

#include <limits>

I am assuming the same patch will apply to 8.8.0 (bug 771921 is the version bump).

I see this package is m-n, but hopefully at least this bug will show the easy fix to anyone who needs it.
