如何为beaglebone配置IP地址？

Question

我按照自由电子教程使用rootfs overlay配置ip地址但是当我运行make时出现了这个错误：

    /sbin/ldconfig.real: Can't open configuration file /home/slim/Bureau/projet_stage/buildroot/output/target/etc/ld.so.conf: No such file or directory
/sbin/ldconfig.real: /usr/lib/libstdc++.so.6.0.19-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

( \
        echo "NAME=Buildroot"; \
        echo "VERSION=2015.05"; \
        echo "ID=buildroot"; \
        echo "VERSION_ID=2015.05"; \
        echo "PRETTY_NAME=\"Buildroot 2015.05\"" \
    ) >  /home/slim/Bureau/projet_stage/buildroot/output/target/etc/os-release

    rsync: change_dir "/home/slim/Bureau/projet_stage/buildroot//board/felabs/beagleboneblack/rootfs-overlay" failed: No such file or directory (2)
    rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1070) [sender=3.0.9]
    make: *** [target-finalize] Error 23

如何将IP地址配置为静态。
