Changes of V2: 1) Fix the Makefile.in to read the t-oe in ${B}/gcc/ 2) Fix the confiure to read the defaults.in ${B}/gcc/
3) Now the only command that would modify ${S} is gnu-configize, but this is compatible, it would do nothing in the second run once config.sub and config.guess were installed to ${S}. 4 I have renamed ${S}/gcc/defaults.h during my testing to confirm that it really use the one in ${B}/gcc. 5) Here is the rough improvement data: gcc-cross, gcc-cross-initial and gcc-cross-intermediate will use the same ${S} and "do_fetch, do_unpack and do_patch", so: a) $ time bitbake gcc-cross -cpatch -f real 0m55.742s so 55s * 2 = 110s will be saved. b) $ du -sh tmp/work-shared/gcc-4.6.0/ 795M tmp/work-shared/gcc-4.6.0/ so 795M * 2 = 1590M (about 1.5G) disk space will be saved. If we also build gcc-crosssdk, then all the 6 buildings will use the same ${S}, then: 55s * 5(About 275s) will be saved. 795M * 5 = 3975M(About 3.9G) disk space will be saved. The following changes since commit 7aa7673459376aff911cef820c9417c998d1aa96: meta-yocto/linux-yocto: update to match the renamed linux-yocto recipes (2011-06-14 09:21:32 -0700) are available in the git repository at: git://git.pokylinux.org/poky-contrib robert/share_gcc http://git.pokylinux.org/cgit.cgi/poky-contrib/log/?h=robert/share_gcc Robert Yang (4): bitbake: share source directory Share gcc work directories gcc-4.5.1: share work directories gcc-4.6.0: share work directories bitbake/lib/bb/build.py | 4 +- bitbake/lib/bb/cache.py | 3 + bitbake/lib/bb/runqueue.py | 10 +++ meta/recipes-devtools/gcc/gcc-4.5.1.inc | 1 + .../gcc-4.5.1/use-defaults.h-and-t-oe-in-B.patch | 57 ++++++++++++++ meta/recipes-devtools/gcc/gcc-4.6.0.inc | 1 + .../gcc-4.6.0/use-defaults.h-and-t-oe-in-B.patch | 80 ++++++++++++++++++++ meta/recipes-devtools/gcc/gcc-common.inc | 32 +++++++- meta/recipes-devtools/gcc/gcc-configure-common.inc | 34 ++++----- 9 files changed, 199 insertions(+), 23 deletions(-) create mode 100644 meta/recipes-devtools/gcc/gcc-4.5.1/use-defaults.h-and-t-oe-in-B.patch create mode 100644 meta/recipes-devtools/gcc/gcc-4.6.0/use-defaults.h-and-t-oe-in-B.patch _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
