Hi again! I think I've found a problem: QtCreator can't resolve FT_CONFIG_OPTION_SUBPIXEL_RENDERING define. It's easy to check: in case of [1] you'll get 3 lines greyed out, in case of [2] - only 1. I suppose it's because of crazy freetype defines like this: #define FT_CONFIG_OPTIONS_H <freetype/config/ftoption.h>, and plus QtCreator can't "go to declaration" in case of FT_CONFIG_OPTION_SUBPIXEL_RENDERING, while I can see it defined when opening ftoption.h.
Also, text.pri used freetype from 3rdparty folder, after removing that folder and adding INCLUDES += /usr/include/freetype2 FT_LCD_FILTER_H define works now. [1] #if defined(FT_CONFIG_OPTION_SUBPIXEL_RENDERING) #if defined(FT_LCD_FILTER_H) #define QT_USE_FREETYPE_LCDFILTER #endif #endif [2] #if defined(FT_LCD_FILTER_H) #if defined(FT_CONFIG_OPTION_SUBPIXEL_RENDERING) #define QT_USE_FREETYPE_LCDFILTER #endif #endif On Thu, Jul 14, 2011 at 11:58 AM, Leandro T.
