AArch64下编译及使用sigar

服务器：鲲鹏裸金属

操作系统：CentOS7.5     AArch64 版

步骤如下:

1. 从github上下载源码   sigar-sigar-1.6.4.tar.gz 

2.将源码上传至服务器上并解压，进入....../sigar-sigar-1.6.4/bindings/java 目录

3.安装ant     # yum install ant -y

4.修改源码： bindings/java/hyperic_jni/src/org/hyperic/jni/ArchNameTask.java，如下图将对应源码注释掉

5.编译

# cd  bindings/java

# ant

编译完成后，编译好的包在   bindings/java/sigar-bin/lib    目录下

6. 安装execstack 工具

# yum install execstack -y

清除共享库需要可执行堆栈的标记，可以使用man 8 execstack查看相关具体说明

# cd bindings/java/sigar-bin/lib

# execstack -c libsigar-aarch64-linux.so

如果不清除可执行堆栈标记，在加载libsigar-aarch64-linux.so的时候将会报以下类似错误：  

OpenJDK 64-Bit Server VM warning: 
You have loaded library  ............./sigar/libsigar-aarch64-linux.so
which might have disabled stack guard. 
The VM will try to fix the stack guard now.It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
............./sigar/libsigar-aarch64-linux.so: ............./sigar/libsigar-aarch64-linux.so: 
invalid ELF header (Possible cause: endianness mismatch)

7. 至此，就可以在AArch64架构服务器下正常使用sigar.jar 和libsigar-aarch64-linux.so 了。
