Dear Developers,
since I upgrade to SuSE 8.2 with Xfree86 4.3.0 and fontconfig 1.0.1 and
Xft.h,v 1.32, I can''t any longer compile an Xft HelloX.c Example.
gcc complains:
/usr/include/X11/Xft/Xft.h:36:35: fontconfig/fontconfig.h: Datei oder
Verzeichnis nicht gefunden [file not found]
and goes on with messages like those:
/usr/include/X11/Xft/XftCompat.h:33: error: parse error before
"XftChar8"
/usr/include/X11/Xft/XftCompat.h:34: error: parse error before
"XftChar16"
.
.
.
I attached the whole example programm and the compile-command.
For any hint tanx in advance,
So long,
Philipp
