下载

到官网上下载最新的spdk 代码。

解决编译依赖

yum install libaio.x86_64 libaio-devel.x86_64

编译dpdk

特别注意的是dpdk:依赖 /lib/modules/uname -a/build 下执行的内核已经存在，并且编译过，为此需要：

• 下载内核；
• 安装依赖；
  yum install ncurses.x86_64 ncurses-devel.x86_64 ncurses-libs.x86_64 ncurses-static.x86_64 ncurses-base.x86_64 ncurses-term.x86_64 ocaml-curses.x86_64

yum install numactl-devel.x86_64 numad.x86_64 numactl.x86_64

make menuconfig && make && make modules && make bzImage

注意用系统自带的gcc make menuconfig 才可以弹出界面；

编译spdk

参考下面命令：

./configure --with-fio=/home/xiaqichao/spdk/fio/fio --with-dpdk=/home/xiaqichao/latestspdk/spdk/dpdk/x86_64-native-linuxapp-gcc --without-virtio --without-vhost
make;
echo "EXTRA_CFLAGS=-fPIC" >> config/defconfig_x86_64-native-linuxapp-gcc && echo && make install T=x86_64-native-linuxapp-gcc DESTDIR=.LINK examples/bdev/fio_plugin/fio_plugin
/home/opt/gcc-4.8.2.bpkg-r4/gcc-4.8.2.bpkg-r4/sbin/../lib/gcc/x86_64-baidu-linux-gnu/4.8.2/../../../../x86_64-baidu-linux-gnu/bin/ld.bfd: cannot find -lnuma
collect2: error: ld returned 1 exit status

[root@s]# cd /
[root@s]# find ./ -name "libnuma*.so"
./usr/lib64/libnuma.so
[root@s]# cp ./usr/lib64/libnuma.so //home/opt/gcc-4.8.2.bpkg-r4/gcc-4.8.2.bpkg-r4/usr/lib
lib/     lib64/   libexec/
[root@s]# cp ./usr/lib64/libnuma.so //home/opt/gcc-4.8.2.bpkg-r4/gcc-4.8.2.bpkg-r4/usr/lib64/

可以通过下面的命令来解决上面的依赖：
yum install numactl-devel.x86_64 numad.x86_64 numactl.x86_64

然后重新编译即可。
