For the development of HarfBuzz, the Microsoft shaping technology, Uniscribe, as a widely used and tested shaper is used as more-or-less OpenType reference implementation and that specially is important where OpenType specification is or wasn't that clear. For having access to Uniscribe on Linux/macOS these steps are recommended:
You want to follow the 32bit instructions. The 64bit equivalents are included for reference.
-
Install Wine.
- Fedora:
dnf install wine
.
- Fedora:
-
Install
mingw-w64
compiler.- Fedora, 32bit:
dnf install mingw32-gcc-c++
- Fedora, 64bit:
dnf install mingw64-gcc-c++
- Debian:
apt install g++-mingw-w64
- Mac:
brew install mingw-w64
- Fedora, 32bit:
-
If you have drank the
meson
koolaid, look at.ci/build-win32.sh
to see how to invokemeson
now, or just run that script. Otherwise, here's how to use the old trusty autotools instead:a) Install dependencies.
- Fedora, 32bit:
dnf install mingw32-glib2 mingw32-cairo mingw32-freetype
- Fedora, 64bit:
dnf install mingw64-glib2 mingw64-cairo mingw64-freetype
b) Configure:
NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild
- 32bit:
../mingw-configure.sh i686
- 64bit:
../mingw-configure.sh x86_64
c) Build as usual:
- make
d) Configure your wine to find system mingw libraries. See: https://fedoraproject.org/wiki/MinGW/Configure_wine
- Fedora, 32bit:
Now you can use hb-shape
by (cd win32build/util && wine hb-shape.exe)
but if you like to shape with the Microsoft Uniscribe:
-
Bring a 32bit version of
usp10.dll
for yourself fromC:\Windows\SysWOW64\usp10.dll
of your Windows installation (assuming you have a 64-bit installation, otherwiseC:\Windows\System32\usp10.dll
) that it is not a DirectWrite proxy (for more info). Rule of thumb, yourusp10.dll
should have a size more than 500kb, otherwise it is designed to work with DirectWrite which Wine can't work with its original one. You want a Uniscribe from Windows 7 or older.Put the DLL in the folder you are going to run the next command,
-
WINEDLLOVERRIDES="usp10=n" wine hb-shape.exe fontname.ttf -u 0061,0062,0063 --shaper=uniscribe
(0061,0062,0063
means abc
, use test/shaping/hb-unicode-decode to generate ones you need)
When you have built that, you can test HarfBuzz's native shaper against Uniscribe following these instructions:
