PangoX cannot find Xlib.h
Hello. I used to have Pango compiled, however it did not have X support, only Freetype support. Since gtk requires pangoX to be compiled, I went to compile it with Xsupport.

I had to issue a
Code:
./configure --prefix=/media/34GB/Arquivos-de-Programas-Linux/PangoX-1.8.2/ PKG_CONFIG_PATH=/media/34GB/Arquivos-de-Programas-Linux/Fontconfig-2.4.0/lib/pkgconfig/:/media/34GB/Arquivos-de-Programas-Linux/Glib-2.6.6/lib/pkgconfig/              --x-includes=/media/34GB/Arquivos-de-Programas-Linux/Xft-2.1.12/include/:/media/34GB/Arquivos-de-Programas-Linux/Xrender-0.9.10/include:/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/include/ --x-libraries=/media/34GB/Arquivos-de-Programas-Linux/Xft-2.1.12/lib/:/media/34GB/Arquivos-de-Programas-Linux/Xrender-0.9.10/lib:/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/lib/

With that, configure detected the X libraries. I tried with only PKG_CONFIG_PATH, passing the .pc files of Xft, X11 and Xrender, however it did not work. Neither using CPPFLAGS and LDFLAGS. Unless of course I made a typo error during the CPPFLAGS or/and LDFLAGS attempt.

Anyway, when compiling pango, it is said:
Code:
pangox.c:26:22: error: X11/Xlib.h: No such file or directory
In file included from pangox.c:32:
pangox.h:37: error: expected declaration specifiers or '...' before '*' token
pangox.h:37: error: expected declaration specifiers or '...' before 'GC' 
......
......

So X11/Xlib.h was not found and hence the myriad of error messages that I omitted. The question is why?

I am passing the directory of X11-1.6.7 with --x-includes and --x-libraries, as configure told me. Why it cannot find the Xlib.h then?

The line 26 of pangox.c it is
Code:
#include <X11/Xlib.h>

since I passed
Code:
.../Xrender-0.9.10/include:/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/include/

it shall add the
Code:
X11/Xlib.h

of the line 26 of pangox.c to the end of
Code:
/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/include/

that I passed through
Code:
--x-includes=

. Hence I expect it to obtain the complete
Code:
/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/include/X11/Xlib.h

and so to find the Xlib.h file! What I am doing wrong them, supposing I really am doing something wrong? And can I fix it? Thanks for you support.
