image-mklibs: ensure sysroot is correctly set when calling gcc

2013-12-11T19:02:38+00:00

[YOCTO #2519]

When getting gcc from sstate, it is possible to get a gcc with a bogus
sysroot configuration, as discussed in [1] or in [YOCTO #2519].

mklibs script will eventually call gcc, so we need to make sure that it
provides gcc with the right sysroot location.

image-mklibs: pass correct libdir to mklibs

2012-08-07T11:54:22+00:00

libdir should be specified, or else mklibs won't work for 64bit targets.
It wouldn't be able to find the libs.

image-mklibs/package_ipk: Remove bashisms

2012-01-05T22:26:20+00:00

We now support using dash but these bashisms triggered build failures for me
when using it. This replaces the code with something which works on dash.

image-mklibs.bbclass: Utilize ${base_libdir} instead of static /lib

2011-08-05T16:13:00+00:00

We might redefine ${base_libdir} from being set to just /lib.

image-mklibs.bbclass: add the library optimization functionality

2011-02-09T22:45:47+00:00

If you want to enable the mklibs library size optimization for your image
then, edit the MKLIBS_OPTIMIZED_IMAGES line in the local.conf like this:

  MKLIBS_OPTIMIZED_IMAGES ?= "poky-image-minimal your-own-image"

Also this will enable the mklibs library size optimization for all images.

  MKLIBS_OPTIMIZED_IMAGES ?= "all"

on qemux86 machine this reduced the rootfs size of poky image-minimal
image from 7.9MB to 7.2MB. That is around 11% image foot print reduction.
That image had 38 elf executables. Generally the size optimization by
mklibs is reversely proportional to the number of elf executables in the
rootfs. So bigger images will see less optimization, and smaller images
will see large image size reductions.

Thanks to mark hatle for his help in implementation of this.
