到官網上下載最新的spdk 代碼。

解決編譯依賴

yum install libaio.x86_64 libaio-devel.x86_64

編譯dpdk

特別注意的是dpdk:依賴 /lib/modules/uname -a/build 下執行的內核已經存在，并且編譯過，為此需要：

• 下載內核；
• 安裝依賴；
  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

注意用系統自帶的gcc make menuconfig 才可以彈出界面；

編譯spdk

參考下面命令：

./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 make[3]: *** [fio_plugin] Error 1 make[2]: *** [fio_plugin] Error 2 make[1]: *** [bdev] Error 2 make: *** [examples] Error 2 [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/

可以通過下面的命令來解決上面的依賴：
yum install numactl-devel.x86_64 numad.x86_64 numactl.x86_64

然后重新編譯即可。
