Inconsistent include paths in libfreetype6-dev between 14.04 and previous releases

[Martin Schaller]

Hi,

the include path of libfreetype6-dev has changed between 14.04 and previous releases.

On 13.10:
$ pkg-config --cflags freetype2
-I/usr/include/freetype2
$ ls /usr/include/freetype2
freetype

so the application used to include <freetype/freetype.h>

On 14.04:
$ pkg-config --cflags freetype2
-I/usr/include/freetype2
(same result)
$ ls /usr/include/freetype2
config ftbzip2.h ftglyph.h ftmac.h ...
(so the stuff used to be in the freetype subdirectory is now in the include path given by pkg-config)

so the application needs now to include <freetype.h>, but this makes it incompatible to previous versions.

Of course one could change to add a second search path to the c compiler including freetype and change the application to include <freetype.h> only, but this isn't exactly nice, and I think the current layout is a mistake.

Best regards,

Martin Schaller

As per <http://www.freetype.org/freetype2/docs/tutorial/step1.html>, the API for freetype requires you to do:

#include <ft2build.h>
#include FT_FREETYPE_H

As this is the only supported interface, and this interface has not changed in 2.5.1 (it worked before and works after, with no modifications), we don't intend to provide compatibility symlinks for the path.
