[Bug 41758] New: wine can' t load freetype if the latter is built with harfbuzz support

https://bugs.winehq.org/show_bug.cgi?id=41758

Bug ID: 41758
           Summary: wine can't load freetype if the latter is built with
                    harfbuzz support
           Product: Wine
           Version: 1.9.23
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdi32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Created attachment 56202

Proposed workaround

If freetype (tried freetype 2.7, wine 1.9.23; probably also valid for other
versions) is built with harfbuzz support, wine complains about:

Wine cannot find the FreeType font library.  To enable Wine to
use TrueType fonts please install a version of FreeType greater than
or equal to 2.0.5.

Adding some debug statements, it turns out that wine_dlopen fails not because
the library isn't there, but because dlopen barfs because it can't resolve
hb_ft_font_create in libfreetype.so.6. (Same for libfontconfig.so.1).

A fix (workaround?) is to use RTLD_LAZY instead of RTLD_NOW when dlopening
freetype and fontconfig -- seems to work well after that.

Patch relative to wine-staging 1.9.23 attached.

So the actual problem is that harfbuzz (potentially 32bit build of it) is not
installed on your system? I think it's better to fail right away than to let it
die in some obscure way when hb_* calls are supposed to be made.

No, the 32bit version of harfbuzz is there and where it belongs, and freetype
is linked to it too

I haven't figured out why hb_ft_font_create remains unresolved despite this so
far (weird load order issue?).
I do know that dlerror() says hb_ft_font_create is the issue. (Btw, the use of
dlerror in wine is rather odd, will file another bug report for that)

I see. Maybe the problem comes from circular dependency - harfbuzz itself
depends on freetype, and it's a hard dependency I think. Freetype dependency on
harfbuzz is optional. In order to build so they both depend on each other
you'll have to build freetype without hb support, then harfbuzz linking to this
newly built freetype and then freetype itself with hb support enabled. Easy
solution would be to make freetype dynamically load harfbuzz when needed, not
sure if something like will be accepted or even considered.
