Hi Folks,
i did some research on building a custom yocto image using gatesgarth branch. The testcase was building an image on one machine and rebuild it on another using sstate mirror.
I encountered two issues witch i was able to fix in a way that may also be interesting upstream.
 
The first error:
| /home/flk/yocto/build/poky-3.2/hd51/tmp/work/cortexa15hf-neon-vfpv4-oe-linux-gnueabi/gobject-introspection/1.64.1-r0/recipe-sysroot-native/usr/bin/bison: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
 
the solution for me was to add 'readline'  to DEPENDS in bison_3.7.2.bb .
 
configure log for bison-native changed from:
 checking for readline... no
checking readline/readline.h usability... no
checking readline/readline.h presence... no
checking for readline/readline.h... no
checking readline/history.h usability... no

checking readline/readline.h presence... yes
checking for readline/readline.h... yes
checking readline/history.h usability... yes
checking readline/history.h presence... yes

and the error disappeared
 
The second error:

Command '/home/flk/yocto/build/poky-3.2/hd60/tmp/work/hd60-oe-linux-gnueabi/neutrino-image/1.0-r0/recipe-sysroot-native/usr/bin/opkg --volatile-cache -f /home/flk/yocto/build/poky-3.2/hd60/tmp/work/hd60-oe-linux-gnueabi/neutrino-image/1.0-r0/opkg.conf -t /home/flk/yocto/build/poky-3.2/hd60/tmp/work/hd60-oe-linux-gnueabi/neutrino-image/1.0-r0/temp/ipktemp/ -o /home/flk/yocto/build/poky-3.2/hd60/tmp/work/hd60-oe-linux-gnueabi/neutrino-image/1.0-r0/rootfs  --force_postinstall --prefer-arch-to-version   update' returned 127:

after some research why libiconv libs are  being used (which i didn't have installed on the rebuild machine) i found this in libarchive:
configure.ac
 
and was able to avoid the error by including 'gettext' to the inherit line in libarchive_3.4.3.bb

Kind regards
