Is it necessary to do the multilib expansion on TARGET_VENDOR ? (See the following patch) It affected many other variables, such as: "HOST_VENDOR, STAGING_BINDIR_TOOLCHAIN, TARGET_SYS, MULTIMACH_TARGET_SYS, REAL_MULTIMACH_TARGET_SYS, SSTATE_PKGSPEC" If we do the modification, there may be potential issues which were caused by the above variables. Any suggestions is welcomed. //Hongxu 46354 2 hongxu.jia 2014-10-16 07:40:00 +0000 While building multilib extended images such as libXX-core-image-minimal, the WORKDIR has the same dir with the building of core-image-minimal. $ ls tmp/work/qemux86_64-poky-linux/ -al ... drwxrwxr-x 3 jiahongxu jiahongxu 4096 Oct 13 16:01 core-image-minimal drwxrwxr-x 3 jiahongxu jiahongxu 4096 Oct 16 11:11 lib32-core-image-minimal ...
