But the above changes did not create multiple library files. While extarcting the toolchain it only create one libgcc.a at location $SDKTARGETSYSROOT/usr/lib/arm-poky-linux-gnueabi/4.9.0/libgcc.a Please help me with your valuable suggestion. Thanks and regards, Atul 44707 1 mark.hatle 2014-07-25 13:53:09 +0000 See: http://lists.openembedded.org/pipermail/openembedded-core/2014-July/094877.html This patch has been provided by the community to attempt to resolve some of the issues. Note, the patch does not work when 'package_rpm' is selected. This is due to some limitations in the way the RPM package resolution occurs. When using IPK, the patch will select multiple packagegroup files instead of just the main system. A second patch is still needed for the packagegroups to be ARCH specific in their dependencies. 44710 2 richard.purdie 2014-07-25 15:12:43 +0000 http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=d8024434d4c9b6a3400ac494fa3c32d0827e42d3 has now merged and that ensures that meta-toolchain/populate_sdk have the appropriate multilib pieces. This *does* work with package_ipk, contra to what Mark mentions, no second patch is needed. There is an rpm issue remaining and it does not work with the package_rpm backend. Reassigning to Mark to find someone to resolve the remaining rpm piece. 55963 3 liezhi.yang 2015-10-29 08:53:59 +0000 Fixed in YP 2.0: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?h=jethro&id=eb7b1a58ceaab7fde4dc954eb4df4247d6c7c6d8
