折腾了大半天，总算将spdk编译通过了。现将编译过程遇到的一些坑记录下来：环境是centos7.2

1、获取spdk 源码

git clone git@github.com:spdk/spdk.git

2、根据github上面的redme 进行如下操作：

sudo dnf install -y gcc gcc-c++ CUnit-devel libaio-devel openssl-devel

# Additional dependencies for NVMe over Fabrics:

sudo dnf install -y libibverbs-devel librdmacm-devel

yum install kernel-devel （kernel-devel 必须要安装，不然会报错make: *** /lib/modules/3.10.0-123.el7.x86_64/build: No such file or directory. Stop.）

3、安装和编译dpdk

1) cd /path/to/spdk

2) wget http://fast.dpdk.org/rel/dpdk-16.11.tar.xz

3) tar xf dpdk-16.11.tar.xz

4) cd dpdk-16.11 && make install T=x86_64-native-linuxapp-gcc DESTDIR=.

注意：在kvm虚拟机上编译的时候，会报如下的错误：

转到物理机上就OK了

4、编译spdk

make DPDK_DIR=./dpdk-16.11/x86_64-native-linuxapp-gcc

我在我的机器上编译的时候会提示没有CUinit 头文件，因此需要安装CUnit， CUint通过源码安装

5、安装和编译CUint

yum -y install gcc automake autoconf libtool make

安装g++:

yum install gcc gcc-c++

1）git clone git@github.com:pi2p/CUnit.git

2) readme.md 里面的说明有错误，按照下面的步骤进行编译和安装

sudo aclocal
sudo autoconf
sudo autoheader
sudo libtoolize
sudo automake --add-missing
sudo automake
sudo mkdir <install directory>
sudo ./configure --prefix <install directory>
sudo make
sudo make install

6、重新编译spdk，通过
