That said, I had a working build for qemuarm (probably doesn't matter) and I added: IMAGE_INSTALL += " strace" This produced a completely broken image which barely came up to a shell, lots of missing programs, etc. I then tried CORE_IMAGE_EXTRA_INSTALL += " strace" which produced a perfectly working build (just as previous) with the new package added. I can see that the images produced are vastly different: * Original working build -rw-r--r-- 1 gthomas gthomas 11719 Jul 18 09:34 core-image-sato-qemuarm-__20140718124453.rootfs.manifest -rw-r--r-- 1 gthomas gthomas 87611203 Jul 18 09:34 core-image-sato-qemuarm-__20140718124453.rootfs.tar.bz2 * After 'IMAGE_INSTALL += ' -rw-r--r-- 1 gthomas gthomas 9986 Jul 18 09:55 core-image-sato-qemuarm-__20140718155134.rootfs.manifest -rw-r--r-- 1 gthomas gthomas 37859884 Jul 18 09:56 core-image-sato-qemuarm-__20140718155134.rootfs.tar.bz2 * After 'CORE_IMAGE_EXTRA_INSTALL += ' -rw-r--r-- 1 gthomas gthomas 11738 Jul 18 10:05 core-image-sato-qemuarm-__20140718160108.rootfs.manifest -rw-r--r-- 1 gthomas gthomas 87720106 Jul 18 10:05 core-image-sato-qemuarm-__20140718160108.rootfs.tar.bz2 What's the difference and why did the first attempt fail? Most likely the image defined its own IMAGE_INSTALL using ?=, so defining it yourself in the configuration data overrode its default definition, since ?= is "set only if unset". If the recipe didn't use ?=, then your IMAGE_INSTALL += would have had no effect at all. To append to IMAGE_INSTALL directly without using CORE_IMAGE_EXTRA_INSTALL you could have used IMAGE_INSTALL_append, since that's a postponed operation that happens at the end of the recipe parsing.
That makes sense, thanks. I'll stick to using CORE_IMAGE_EXTRA_INSTALL from now on! -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
