[sane-devel] Build git master

[Jeroen Van den Keybus]

Hi Povilas,


g++ is installed alright, also version 9.1.1. Autoconf is at version
2.69-16.6.
>From the ./configure output, it seems that configure actually detects that
C++11 is supported:

...
checking whether g++ supports C++11 features with -std=c++11... yes
...
*** genesys backend requires C++11 support - disabling
...

I have little experience with autoconf / configure, so I'm a bit lost here.


J.
