[Pkg-deepin-devel] Bug#1092315: deepin-music ftbfs with icu 76.1

[Matthias Klose]

Package: src:deepin-music
Version: 6.2.18-2
Severity: important
User: debian-devel at lists.debian.org
Usertags: icu76

The package fails to build with icu 76.1-2 from experimental.  The most 
likely reason is that it's not built for the default C++17 standards, 
and manually specifies an earlier standard.

The build log shows the package building with -std=c++11, and failing.
