Bugzilla Bug 179734

Amanith does not compile for me with USE=truetype, and appears to want internal
freetype headers. The amanith ebuild DEPENDS on
truetype? ( >=media-libs/freetype-2.1.10 )

It of course builds fine with USE="-truetype".

I tried to look for the header in question, but I can't connect to freetype.org
at the moment.

Stop using internal FreeType headers

Here's a patch that will make amanith compile with freetype > 2.2.1.

Created an attachment (id=121009) [edit]
Updated ebuild

Updated to ebuild to use the patch. Also changed freetype dep to >=2.2.1 to
enable the use of FT_Get_SubGlyph_Info instead of internal headers.

Fortunately, Amanith developers had previously asked FreeType developers about
this, and in 2.2.1 the FT_Get_SubGlyph_Info function was added to help those
people who had previously been using internal headers. [1]
The patch just removes the internal header and uses the new function. The
ebuild needed to be updated to depend on >=media-libs/freetype-2.2.1 so that
this function is available. It compiles and seems to work fine (doesn't cause
problems with fretsonfire, at least).

Patch and ebuild work great. Thanks Elliott.

fixed in cvs, cheers
