Hi Christopher thanks for this hint, this prevented a lot of packages from being built. However I still face an additional issue. in the last step of do_populate_sdk, when the sdk is actually supposed to be put together. I get this output:
Collected errors: * satisfy_dependencies_for: Cannot satisfy the following dependencies for packagegroup-core-standalone-sdk-target: * libc6 (= 2015.08-r0) * glibc-utils * * opkg_install_cmd: Cannot install package packagegroup-core-standalone-sdk-target. how can it be, that everything is built correctly and in the end there is a dependency missing? I tried altering my LIBC_DEPENDENCIES, but with no success so far. I am also using tclibc-external-linaro-toolchain.inc from http://arago-project.org/git/?p=meta-arago.git;a=blob;f=meta-arago-extras/conf/distro/include/tclibc-external-linaro-toolchain.inc;hb=HEAD any comments are appreciated regards Thomas From: Christopher Larson [mailto:[email protected]] Sent: Wednesday, February 10, 2016 5:25 PM To: Thomas Kaufmann; [email protected] Subject: Re: [yocto] Yocto/Poky with external linaro toolchain https://github.com/MentorEmbedded/meta-mentor/blob/master/meta-mel/conf/include/drop-toolchain-from-sdk.inc may be of interest to you.

The hardware TI am 335x based. I want to use the external linaro toolchains. Since I use an existing 3.2 linux kernel as well as an older u-boot, I created a own machine and distro configuration. I succeed to build and run the target, so far so good. To incorporate the external toolchains I added TCMODE = "external-linaro" EXTERNAL_TOOLCHAIN = "/<homedir>/gcc-linaro-5.1-2015.08-x86_64_arm-linux-gnueabihf" to the local.conf file and meta-linaro/meta-linaro-toolchain to the BBLAYERS in bblayers.conf. meta-linaro was cloned using git. For my "legacy" packages I adjust "EXTERNAL_TOOLCHAIN" to a gcc-4.9 version, this seems to work and everything compiles. Now my next step is to create an SDK distribution. When I do do_populate_sdk with bitbake for my image, however the process seems to compile a new cross compiler for the target as well as various qemu things and also newer kernel releases. Is this the preferred way to integrate the linaro toolchain into poky? Can anybody share their experience? I find various presentations and snippets about this topic, but nothing is complete. How do I create a SDK distribution which does not feature any QEMU (I want to deploy to target hardware) and uses the existing prebuilt toolchain? Build host and target sdk host would be x86_64. Any recommendations are welcome. regards Thomas Kaufmann -- _______________________________________________ yocto mailing list [email protected]<mailto:[email protected]> https://lists.yoctoproject.org/listinfo/yocto
