I have found good documentations on this known problem of compiling Freetype related to Harfbuzz: http://www.gregwessels.com/dev/2017/05/02/freetype-harfbuzz.html and here 44184890
But they seem obsolet nowadays: freetype-2.9 with harfbuzz-1.7.6
Here is my way compiling:
- download Freetype tarball
- extract the tarball...
- open builds\windows\vc2010\freetype.sln
- it must already Generate well (as dll)
- download Harfbuzz
- extract the tarball next to freetype...
- run
cmake ./at root level to obtain a.sln - it must already Generate well (as lib)
At this point you have 2 separate libs not working together which means:
Freetype will not open GSUB scripts of your fonts. (or maybe I am wrong)
To do so, I need help! I also need confirmations!!!
Is seems to be needed to enable the use of Harfbuzz in Freetype at compile time; I have found a precompiler directive called FT_CONFIG_OPTION_USE_HARFBUZZ
But when activating it, I have some compile link errors when using both libs in a third project:
autofit.obj : error LNK2019: external symbol not found _hb_ft_font_create referenced in function _af_face_globals_new
Good to know, hb_ft_font_create is an extern function in harfbuzz.
So it seems to be a cyclic extern problem... I certainly don't have the good config at a point, but I have browsed many docs and helps, found nothing...
-- edit -- After both pojects decompression, you have normaly to obtain such a tree:
