[QGIS-Developer] Problem compiling QGIS on Debian stretch

[Tom Palan]

Hi,

I am having problems compiling QGIS 3.10.3 on Debian stretch. The compile does work flawlessly on Debian buster.
Is compiling on Debian stretch not supported anymore?

The error message after mkdir build && cd build && cmake .. && make is:

Does anybody have an idea?
I am using the std GCC version 6.3

thanks for your input,
