I ran into various issues trying to add mtd-utils to an image today. As I worked through the issues, I found after fixing a couple things, I was more guessing and grasping at straws than anything else. I'll recount what I did, and if anyone can offer a better approach to what I did that would have resulted in a more deterministic result, I'd appreciate it very much.
I copied meta-tiny to a new layer. I disabled uclibc (so I'm building with eglibc). I added mtd-utils from OE and used the DEPENDS line using util-linux (and not util-linux-ng which we don't have in yocto). This resulted in ncurses failing the qa configure with host contamination with the widec headers. I first attempted to enable widechar support in my DISTRO_FEATURES_LIBC, and rebuild eglibc. This didn't solve the problem. This turns out to be due to ncurses configuring in widechar support regardless of whether or not you plan to use it (it does a widec and a narrowc configure and only builds and installs widec if you set ENABLE_WIDEC="true". I set that to false and hacked out the widec config step which allowed ncurses to build. I'll send a proper fix for this tomorrow. The next failure was with gettext compilation. Several errors about wchar related functions being redefined in incompatible ways. I thought this might be related to DISTRO_FEATURES_LIBC changes I made, so I commented them all out and rebuilt eglibc so it should be using the default Poky distro configuration for eglibc (which I assumed gettext was known to compile with). Gettext would still not compile, claiming the redefined functions were first defined in /usr/include/wchar.h. Confused, thinking I had just rebuilt eglibc, I did another cleanall of eglibc and gettext and a rebuild. Same result. Not trusting the sanity of my tmp tree at this point, I deleted tmp and pseudodone and rebuilt the image. Everything succeeded and my final image with mtd-utils included was built. I tried to capture my complete log, but screen froze on me while trying to paste the buffer into a log :( So besides writing a bitbake wrapper to ensure I record ALL my bitbake sessions for reference, what would you recommend I change in the above process? What could I have done to either avoid deleting tmp or to have identified a possible bug that required me to delete tmp?
