From: Nitin A Kamble <nitin.a.kam...@intel.com> These commits add infrastructure to the oe-core/yocto to add the meta-x32 layer to build x32 images. core-image-minimal has been tested to work with this commits
=== How to build an image with x32 binaries Add this layer on top of yocto/oe-core http://git.pokylinux.org/cgit/cgit.cgi/experimental/meta-x32/ Add these lines in your conf/local.conf MACHINE = "qemux86-64" DEFAULTTUNE = "x86-64-x32" TUNE_PKGARCH = "x86-64-x32" And build the minimal image with command: bitbake core-image-minimal And then run it with qemu with this command: runqemu qemux86-64 core-image-minimal === How to know if your binaries/libraries are x32: Run the file command to know what type of elf binary is it. It should be 32bit x86-64 elf binary as seen here: $ file bin/busybox bin/busybox: setuid ELF 32-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.35, not stripped $file usr/lib/libz.so.1.2.5 usr/lib/libz.so.1.2.5: ELF 32-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped The following changes since commit f94b781695cd8fa387daff16ecbf3987a0883018: poky.conf: explicitly referenced preferred linux-yocto version (2011-07-27 09:56:56 -0700) are available in the git repository at: git://git.pokylinux.org/poky-contrib nitin/x32 http://git.pokylinux.org/cgit.cgi/poky-contrib/log/?h=nitin/x32 Nitin A Kamble (4): toolchain-scripts & other classes: add TARGET_LD_ARCH & TARGET_AS_ARCH vars siteinfo.bbclass: add entries for new x86_64 ABI targets insane.bbclass: add entries for linux-gnu<ABI> x86 tune inc files: add x32 abi tune parameters meta/classes/allarch.bbclass | 2 ++ meta/classes/cross-canadian.bbclass | 2 ++ meta/classes/cross.bbclass | 2 ++ meta/classes/crosssdk.bbclass | 2 ++ meta/classes/insane.bbclass | 9 +++++++++ meta/classes/native.bbclass | 10 +++++++--- meta/classes/nativesdk.bbclass | 4 ++++ meta/classes/siteinfo.bbclass | 14 +++++++++++++- meta/classes/toolchain-scripts.bbclass | 9 +++++---- meta/conf/bitbake.conf | 23 +++++++++++++++++------ meta/conf/machine/include/ia32/arch-ia32.inc | 23 ++++++++++++++++++++--- meta/conf/machine/include/tune-core2.inc | 4 ++++ meta/conf/machine/include/tune-x86_64.inc | 2 +- 13 files changed, 88 insertions(+), 18 deletions(-) -- 1.7.4.4 _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
