标题: 办理鲲鹏arm服务器运行vdbench50406
项目场景：

通常从oracle官网下载的工具是基于x86架构。在鲲鹏arm平台上，直接使用vdbench50406，会产生“缺少aarch64.so文件”的报错。
因此，若想正常使用，这里需要办理“aarch64.so”重新编译的问题。
问题形貌

1.缺少共享库“aarch64.so”而产生的报错：
比方：
  1. root@client:~$ ./vdbench -t

复制代码
缘故起因是vdbench根目次下/linux/linux64.so是为x86编译的,需要重新编译linux64.so

  1. root@client:~$ file linux/linux64.so
  2. linux/linux64.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=34a31f32956f21153c372a95e73c02e84ddd29f8, not stripped
复制代码
ARM版本的aarch64.so编译

下载，解压源码包： 需要同意license
下载地点：https://www.oracle.com/downloads/server-storage/vdbench-source-downloads.html

  1. unzip vdbench50406.src.zip
复制代码
进入src创建linux目次
  1. cd src/
  2. mkdir linux
复制代码
进入Jni修改make.linux。主要修改: + 修改vdb为源码包src的路径 + 修改java为jdk路径。一样平常在/usr/lib/jvm/下 + 去除-m32和m64选项
  1. cd Jni/
  2. vim make.linux
复制代码
参考如下修改方法:
  1. ###修改1###
  2. --- vdb=$mine/vdbench504
  3. --- java=/net/sbm-240a.us.oracle.com/export/swat/swat_java/linux/jdk1.5.0_22/
  4. +++ vdb=/home/user1/open_software/vdbench/src
  5. +++ java=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.aarch64/
  7. ###修改2###
  8. --- INCLUDES32="-w -m32 -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
  9. --- INCLUDES64="-w -m64 -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
  10. +++ INCLUDES32="-w -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
  11. +++ INCLUDES64="-w -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
  13. ###修改3###
  14. --- gcc  -o   $vdb/linux/linux32.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o -lm -shared  -m32 -lrt
  15. +++ gcc  -o   $vdb/linux/linux32.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o -lm -shared -lrt
  17. ###修改4###
  18. --- gcc  -o   $vdb/linux/linux64.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o -lm -shared -m64 -lrt
  19. +++ gcc  -o   $vdb/linux/linux64.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o -lm -shared -lrt
复制代码
执行make.linux，会在src/linux/下天生linux32.so和linux64.so文件，我们这里需要的是天生的64位的文件。
但这里会产生报错：
  1. [root@client Jni]# ./make.linux
  2. target directory: /tmp/test50406/src
  3. Compiling 32 bit
  4. In file included from /tmp/test50406/src/Jni/vdbjni.c:13:

  37. /tmp/test50406/src/Jni/vdbjni.h:87:16: error: duplicate ‘unsigned’
  38. ......
复制代码
根据报错内容，我们需要再次修改源码包中的‘’vdbjni.h‘’文件。
修改如下：
  1. ###将这三句话注释掉##
  2. #define uint   unsigned int
  3. #define uchar  unsigned char
  4. #define ushort unsigned short
  6. ###替换成这三句话###
  7. typedef unsigned int   uint;
  8. typedef unsigned char  uchar;
  9. typedef unsigned short ushort;
复制代码
如图：

再次编译即可通过：
  1. root@client:~/vdbench50406/src/Jni$ ./make.linux
  2. target directory: /xxx/vdbench50406/src/
  3. Compiling 32 bit
  4. Linking 32 bit
  6. Compiling 64 bit
  7. Linking 64 bit
  9. cp linux64.so aarch64.so
  10. cp aarch64.so ~/vdbench50406/linux/
复制代码
这里我们将天生的linux64.so重定名为aarch64.so并复制到二进制包（注意不是源码包）的linux/目次下即可。
放到这个位置：

再次验证即可正常使用。
