Currently adding a font recipe to an image doesn't have enough
dependencies to cause mkfontdir-native to be included in the native
sysroot. This creates problems with the postinstall scripts for fonts
which call mkfontdir to create font index files: font.dir. The end
result is missing font.dir files in the built image and a malfunctioning
font system.
Dependencies for the relevant recipes currently look like this:
* <font.bb> [D ] -> font-util-native
[R ] -> encodings, font-util
[RN] -> font-util-native
* font-util [D ] -> encodings
[R ] -> mkfontdir, mkfontscale, encodings
[RN] -> mkfontdir-native, mkfontscale-native
* encodings [D ] -> mkfontscale-native, font-util-native
* mkfontdir [R ] -> mkfontscale
[RN] -> mkfontscale-native
* mkfontscale [D ] -> libfontenc
* libfontenc [D ] -> font-util
Where:
* D = DEPENDS
* R = RDEPENDS
* RN = RDEPENDS_class-native
* <font.bb> e.g. font-adobe-100dpi*.bb
Some details where omitted for clarity e.g. dependencies on util-macros.
I believe the intent behind the RDEPENDS_class-native chain:
* <font.bb> -> font-util-native -> mkfontdir-native
was to provide the necessary dependency on mkfontdir. However because
the native sysroot is not built from packages this RDEPENDS_class-native
chain doesn't have the desire effect (i.e. it doesn't pull in
mkfontdir-native).
Changing the RDEPENDS_class-native chain into a DEPENDS_class-native
chain is a non-starter because of the build time dependency loop it
creates:
* font-util-native -> mkfontscale-native -> libfontenc-native -> font-util-native
Having upstream remove the build time dependency of libfontenc on
font-util is also a non-starter[1] even though it does create problems
in other distributions, for example on Debian see [2], [3].
Instead add a DEPENDS on mkfontdir-native in the encodings recipe in
addition to the mkfontscale-native dependency it already contains. This
solves the missing mkfontdir in the native sysroot problem without
introducing a build dependency loop.
