[Debian-med-packaging] Bug#939506: expected primary-expression before ‘{’ token (Was: Bug#939506: unanimity ftbfs in unstable)

[Andreas Tille]

Hi again,

I forgot to mention that I bounced your mail to the bug log of #939506
and I also CC this one to make sure there is some publicly visible
record of the discussion.  What I forgot to mention in my mail:  It
seems that upstream (Pacific Biosciences) switches lots of their
programs to meson.  It could be that simply switching the Debian
packaging to meson would help.

Kind regards

    Andreas.
