I see this as first error

/pub/devel/opencv/opencv-3.4.1-3.x86_64/src/opencv-3.4.1/modules/python/src2/cv2.cpp:889:34: 
error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive]
it seems the compilers is less tolerant than before.
It does not seem a specific python issue.

I will see to patch it and continue when I found a bit of time
