解决鲲鹏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，这里需要解决“aarch64.so”重新编译的问题。

问题描述

1.缺少共享库“aarch64.so”而产生的报错： 例如：

root@client:~$ ./vdbench –t

原因是vdbench根目录下/linux/linux64.so是为x86编译的,需要重新编译linux64.so

root@client:~$ file linux/linux64.so
linux/linux64.so: ELF 64–bit LSB shared object, x86–64, version 1 (SYSV), dynamically linked, BuildID[sha1]=34a31f32956f21153c372a95e73c02e84ddd29f8, not stripped

ARM版本的aarch64.so编译

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

unzip vdbench50406.src.zip

进入src创建linux目录

cd src/
mkdir linux

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。一般在/usr/lib/jvm/下 + 去除-m32和m64选项

cd Jni/
vim make.linux

参考如下修改方法:

###修改1###
—– vdb=$mine/vdbench504
—– java=/net/sbm–240a.us.oracle.com/export/swat/swat_java/linux/jdk1.5.0_22/
+++ vdb=/home/user1/open_software/vdbench/src
+++ java=/usr/lib/jvm/java–1.8.0–openjdk–1.8.0.232.b09–0.el7_7.aarch64/

###修改2###
—– INCLUDES32="-w -m32 -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
—– INCLUDES64="-w -m64 -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
+++ INCLUDES32="-w -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
+++ INCLUDES64="-w -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"

###修改3###
—– gcc –o $vdb/linux/linux32.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o –lm –shared –m32 –lrt
+++ gcc –o $vdb/linux/linux32.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o –lm –shared –lrt

###修改4###
—– gcc –o $vdb/linux/linux64.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o –lm –shared –m64 –lrt
+++ gcc –o $vdb/linux/linux64.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o –lm –shared –lrt

执行make.linux，会在src/linux/下生成linux32.so和linux64.so文件，我们这里需要的是生成的64位的文件。 但这里会产生报错：

[root@client Jni]# ./make.linux
target directory: /tmp/test50406/src

......

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：

###将这三句话注释掉##
#define uint unsigned int
#define uchar unsigned char
#define ushort unsigned short

###替换成这三句话###
typedef unsigned int uint;
typedef unsigned char uchar;
typedef unsigned short ushort;

如图：

再次编译即可通过：

root@client:~/vdbench50406/src/Jni$ ./make.linux
target directory: /xxx/vdbench50406/src/
Compiling 32 bit
Linking 32 bit

Compiling 64 bit
Linking 64 bit

cp linux64.so aarch64.so
cp aarch64.so ~/vdbench50406/linux/

这里我们将生成的linux64.so重命名为aarch64.so并复制到二进制包（注意不是源码包）的linux/目录下即可。

放到这个位置： 再次验证即可正常使用。
