It actually was "pkg-config --cflags xft" (without any difference, though, because its output is an empty string): $ pkg-config --cflags xft $ The problem here is that some headers required by X11/Xft/Xft.h are not installed because they are not required via xft.pc. Similar issue arose in libXt recently, and it was resolved in https://bugs.freedesktop.org/show_bug.cgi?id=26943#c3 as a non-issue. Is there any legal way now for libXft callers to find out what packages have to be installed to #include <X11/Xft/Xft.h>?

Use a non-broken version of pkg-config, as the correct behavior according to the FAQ is to include -I flags for Requires.private, and at least the version on my system correctly does that: % grep Requires /usr/X11R7/lib/pkgconfig/xft.pc Requires: xproto Requires.private: xrender, fontconfig, freetype2 % env PKG_CONFIG_PATH=/usr/X11R7/lib/pkgconfig pkg-config --cflags xft -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -I/usr/X11R7/include -I/usr/include/freetype2 % pkg-config --version 0.23 If you want to hold a discussion, please use the mailing list - bugzilla is not a very interactive forum, and questions raised here won't be seen by most developers. (In reply to comment #4) > % grep Requires /usr/X11R7/lib/pkgconfig/xft.pc > Requires: xproto > Requires.private: xrender, fontconfig, freetype2 $ grep '^#include <X11/' /usr/include/X11/Xft/Xft.h #include <X11/extensions/Xrender.h> #include <X11/Xfuncproto.h> #include <X11/Xft/XftCompat.h> This is exactly the problem: according to X11/Xft/Xft.h, there is no difference between xproto and xrender -- both libraries are equally necessary to compile with libXft, so I'm sure both must be in Requires list. > If you want to hold a discussion, please use the mailing list - bugzilla > is not a very interactive forum, and questions raised here won't be seen > by most developers.
