[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] Re: #5545 Compatibility with pango 1.44

[Auto mailings of changes to Lily Issues via Testlilyissues-auto]

That concerns the compilation error which is a bit tangential to the issue. Even if the interfaces were superficially completely binary compatible, when there are substantial reductions in functionality making it unavoidable to be using two different versions of the library at the same time, the library numbers have to be changed. Only straightforward extensions in functionality and bug fixes can afford to keep the same numbers because only then there is no incentive to use more than one version of the library at the same time.

[issues:#5545] Compatibility with pango 1.44

Status: Accepted

Reported by T. Sefzick:

With the new pango version 1.44 compilation of

src/lilypond/lily/pango-font.cc

gives warnings about
'void* pango_fc_font_lock_face(PangoFcFont*)'
to be deprecated and
'pango_font_get_hb_font'
should be used instead.

followed by
error: invalid conversion from 'gpointer' {aka 'void*'} to 'FT_Face' {aka 'FT_FaceRec_*'}

Seems that pango doesn't work with freetype fonts anymore.

A side note: lilypond executables compiled with pango <=1.43
produce an empty 1st page when run with pango 1.44 installed.
