Well, I'm not sure it has to be done this way: actually harfbuz is in the
"recommended" dependency chain of cairo: cairo recommends fontconfig, which
recommends freetype, which recommends harfbuzz...
I do not know whether you use jhalfs. If cairo got built before harfbuzz using
jhalfs, this is most probably a bug in jhalfs, so please tell me.
I do not use jhalfs for BLFS (but it's critical for me in LFS). As I build
for a release I try to get most of the optional dependencies as sell as the
required and recommended. That does create some circular dependencies and it
bit me when I tried to build pango.
But that shouldn't happen, since harfbuzz is recommended (not directly, but it
is) for cairo. I'll do the following:
- on the harfbuzz page: note that the optional dep on cairo is circular, and
that it is recommended to build harfbuzz first
- on the cairo page: remove the optional dep on harfbuzz (it is already in the
recommended chain), which can only add confusion.
I thought we were only omitting deps in the required chain.
