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

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

Well, Pango did drop Type1 support...

Regarding the 1.44 issue: There have been reports that a lilypond binary compiled against Pango 1.43 doesn't work with 1.44 .so libraries (using OpenType fonts). If this can be confirmed (can you do that?) we have a serious bug in Pango itself since they broke ABI backward compatibility; this should be reported as such, and the Pango guys have to increase the .so major number correctly – or fix the ABI.

Of course, we should make LilyPond compile with newer Pango versions, too.

[issues:#5545] Compatibility with pango 1.44

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.
