Hi，all I got a big problem when using the cross-toolchain to compile a simple C program. This problem since 3ae71c74c71f13a390b21b4c3ead04e51aaa82b8 which is to upgrade the binutils from 2.22 to 2.23.1
what I do is as follows, any help or ideas ? I) Build my cross-toolchain # git clone http://git.yoctoproject.org/git/poky/.git # cd poky # git checkout 3ae71c74c71f13a390b21b4c3ead04e51aaa82b8 -b tcmode-default ...skip some steps... # bitbake meta-toolchain Loading cache: 100% |############################################################################################| ETA: 00:00:00 Loaded 1122 entries from dependency cache.
