audiofile @0.3.6: error: in-class initializer for static data member is not a constant expression

[kostix (Konstantin Khomoutov)]

I had mpd installed on Sequioia (15.x), and audiofile - as its dependency. Now I've upgraded the system to Tahoe 26.2, issued port migrate and audiofile failed to build.

Build log

The log shows lots of errors I'm not familiar with, starting with:

In file included from SimpleModule.cpp:22:

Our buildbot also couldn't build this port on Tahoe.

Probably ought to ​report the problem to the developers but there's been no activity there in nine years.

Maybe another distribution has a patch for this already.

[kostix (Konstantin Khomoutov)]

Hi, Ryan!

I've found ​this changeset in the FreeBSD FreshPorts; can you try to partially pick it? (Or maybe even completely - I'm at a loss whether that do-test target the patch adds to the Makefile is specific to FreshPorts or it really gets called by some code in the audiofile build system.)

[kostix (Konstantin Khomoutov)]

Actually, the ​whole FreshPorts' page on `audiofile` looks interesting and it appears as something to keep an eye on ;-)
