These patches are now available in my contrib/dvhart/modules branch. I've tried with both rpm and ipk root_fs packaging and get the same result. If I include hello-world-mod in the image, the /lib/modules/KERNELVER/kernel directory isn't present in the final rootfs, for example: BUILDING WITHOUT hello-world-mod in the image: dvhart@rage:build$ ls tmp/sysroots/qemux86/lib/modules/2.6.37.2-yocto-standard+ build extra kernel modules.builtin modules.order source dvhart@rage:build$ ls tmp/sysroots/qemux86/lib/modules/2.6.37.2-yocto-standard+/kernel/fs autofs4 binfmt_misc.ko cifs configfs jbd2 minix nls ocfs2 quota reiserfs romfs dvhart@rage:build$ ls tmp/work/qemux86-poky-linux/poky-image-sato-1.0-r0/rootfs/lib/modules/2.6.37.2-yocto-standard+ kernel modules.ccwmap modules.devname modules.isapnpmap modules.seriomap modules.symbols.bin modules.alias modules.dep modules.ieee1394map modules.ofmap modules.softdep modules.usbmap modules.alias.bin modules.dep.bin modules.inputmap modules.pcimap modules.symbols dvhart@rage:build$ ls tmp/work/qemux86-poky-linux/poky-image-sato-1.0-r0/rootfs/lib/modules/2.6.37.2-yocto-standard+/kernel/fs/ nls dvhart@rage:build$ ls tmp/work/qemux86-poky-linux/poky-image-sato-1.0-r0/rootfs/lib/modules/2.6.37.2-yocto-standard+/kernel/fs/nls/ nls_utf8.ko BUILDING WITH hello-world-mod in the image: dvhart@rage:build$ ls tmp/sysroots/qemux86/lib/modules/2.6.37.2-yocto-standard+ build extra kernel modules.builtin modules.order source dvhart@rage:build$ ls tmp/sysroots/qemux86/lib/modules/2.6.37.2-yocto-standard+/extra/ hello_world.ko dvhart@rage:build$ ls tmp/sysroots/qemux86/lib/modules/2.6.37.2-yocto-standard+/kernel/fs autofs4 binfmt_misc.ko cifs configfs jbd2 minix nls ocfs2 quota reiserfs romfs dvhart@rage:build$ ls tmp/work/qemux86-poky-linux/poky-image-sato-1.0-r0/rootfs/lib/modules/2.6.37.2-yocto-standard+ extra modules.ccwmap modules.devname modules.isapnpmap modules.seriomap modules.symbols.bin modules.alias modules.dep modules.ieee1394map modules.ofmap modules.softdep modules.usbmap modules.alias.bin modules.dep.bin modules.inputmap modules.pcimap modules.symbols Still digging, but I'm mostly just stumbling around in the dark. -- Darren > Gary, can you try the module.bbclass with your module to see if it > builds successfully? > > Thanks, > > Darren Hart (2): > module: build and clean hostprogs for each module > hello-world-mod: add a module for testing module.bbclass > > meta/classes/module.bbclass | 21 ++- > meta/recipes-kernel/hello-world-mod/files/COPYING | 340 ++++++++++++++++++++ > meta/recipes-kernel/hello-world-mod/files/Makefile | 14 + > .../hello-world-mod/files/hello_world.c | 33 ++ > .../hello-world-mod/hello-world-mod.bb | 15 + > 5 files changed, 422 insertions(+), 1 deletions(-) > create mode 100644 meta/recipes-kernel/hello-world-mod/files/COPYING > create mode 100644 meta/recipes-kernel/hello-world-mod/files/Makefile > create mode 100644 meta/recipes-kernel/hello-world-mod/files/hello_world.c > create mode 100644 meta/recipes-kernel/hello-world-mod/hello-world-mod.bb > > _______________________________________________ > poky mailing list > poky@yoctoproject.org > https://lists.yoctoproject.org/listinfo/poky -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel
