Re: [Gimp-developer] Cross compiling gimp with mingw-w64 requires pangoft2 that is not available

[YuGiOhJCJ Mailing-List <yugiohjcj-mailinglist laposte net>]

Indeed, I have not installed harfbuzz because I thought it was an optional dependency that I don't need to 
build gimp.

You compiled pango with freetype/harfbuzz/cairo on Windows 10 64 bit.
But what I am doing is a bit different: I am cross-compiling pango for Windows 32 bit on Linux 32 bit.

Anyway, interesting that you get the pangoft2-1.0-0.dll file because that is exactly what I need to build.

I have cross-compiled and installed harfbuzz and its icu4c dependency:
- icu4c-56.1
- harfbuzz-1.2.3-i486-20160311152555

But now with these new programs installed, I am not anymore able to cross-compile pango:
---
$ ./configure --prefix=/usr/i686-w64-mingw32 --host=i686-w64-mingw32
$ make

An interesting thing is that when I don't have harfbuzz, that's what I see:
---
$ ./configure --prefix=/usr/i686-w64-mingw32 --host=i686-w64-mingw32
[...]
configuration:
        backends: Cairo Win32
[...]
---

Whereas when I have harfbuzz, that's what I see:
---
[...]
configuration:
        backends: Cairo Win32 FreeType
[...]
---

So, it means that having harfbuzz installed enables the FreeType backend on pango.
It means that it enables the building of pangoft2-1.0-0.dll.
Exactly what I want :)

But why I got this "undefined reference to `cairo_ft_font_face_create_for_pattern'" error please?
