Possibly two ways to fix the problem: 1) Check whether MULTILIB is arm or armeb, if yes, then use "-gnueabi", else no 2) Use a in sysroot to save "-gnueabi". 63855 1 ross.burton 2016-07-12 16:40:04 +0000 There's a branch under review at http://cgit.openembedded.org/cgit.cgi/openembedded-core-contrib/log/?h=ChenQi/aarch64-multilib. 66788 2 richard.purdie 2016-10-01 21:04:29 +0000 http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=b6253350fb86d8e54792905342a5892af570d526 66790 3 richard.purdie 2016-10-01 21:05:19 +0000 *** Bug 10054 has been marked as a duplicate of this bug. ***
