tcmu-runner编译

之前使用的是tcmu-runner的1.3.0版本，看了一下github上面最新的是1.5.2准备拿来更新一下，看看有没有什么性能的优化

源码编译

1.下载源码包
这个可以直接在github上面下载

2.编译有问题

[root@master ~/tcmu-runner/tcmu-runner-1.5.2]# make
[  2%] Building C object CMakeFiles/tcmu.dir/libtcmu.c.o
/root/tcmu-runner/tcmu-runner-1.5.2/libtcmu.c:38:37: error: 'NLA_S32' undeclared here (not in a function)
  [TCMU_ATTR_CMD_STATUS] = { .type = NLA_S32 },
                                     ^

  ret = nla_put_s32(msg, TCMU_ATTR_CMD_STATUS, status);
  ^

make[2]: *** [CMakeFiles/tcmu.dir/libtcmu.c.o] Error 1
make[1]: *** [CMakeFiles/tcmu.dir/all] Error 2
make: *** [all] Error 2

说没有NLA_S32和nla_put_s32定义，看了一下代码，有头文件导入

1
2
3

#include <libnl3/netlink/genl/genl.h>
#include <libnl3/netlink/genl/mngt.h>
#include <libnl3/netlink/genl/ctrl.h>

在系统头文件/usr/include进行搜索，发现应该在这个文件中

1	/usr/include/libnl3/netlink/attr.h

但是没有，该开始以为是内核的头文件，后来看一下是

1 2	[root@master ~/tcmu-runner/tcmu-runner-1.5.2]# rpm -qf /usr/include/libnl3/netlink/attr.h libnl3-devel-3.2.28-4.el7.x86_64

是这个包libnl3-devel版本有点低，代码中没有定义NLA_S32，这个是一个无符号32位，所以升级，上面的3.2.28便是我升级后的版本

3.编译

make一下编译完成

更新二进制

ldd和pldd看一下tcmu-runner二进制和进程依赖哪些动态库，发现有libtcmu.so和handler_rbd.so，所以替换这两个动态库加上tcmu-runner二进制就可以
