Hi,
I decided to modify the bash and busybox recipes to build statically,
and try to create a core-image-minimal root filesystem, so that I can get a
sensible prompt with paths set, etc, to debug the dynamic linking issue.
Just copying a static bash binary to the root of the ramdisk image and
specifying init=/bash didn't work for a static bash+core-image-minimal root
filesystem, it aborts with a panic. If I have only the bash executable in the
ramdisk and nothing else, it displays the bash prompt.
Now, I've noticed something weird during core-image-minimal image generation.
When I build the static versions of bash, the size of the binary is 8MB, but
when I explore the binary in the tar.gz image or extract it to my ramdisk, it
shows as being only 1.6MB.
How can there be a difference between the statically built bash file
/tool/yocto/poky/build/tmp/work/ppc440-poky-linux/bash-4.2-r4/image/bin/bash
(8MB)
and in the file contained in the core-image-minimal-virtex-5.tar.gz
/bin/bash (1.6MB)
I'm seeing the same discrepancy for busybox
/tool/yocto/poky/build/tmp/work/ppc440-poky-linux/busybox-1.19.4-r18/image/bin/busybox
(8.2 MB)
and in the generate rootfs image
/bin/busybox (1.4MB)
This shouldn't happen, right?
Best regards,
Elvis Dowson
