Hyperic Sigar Mac Osx错误 - 无库

Question

嗨我使用第三方lib名称Hyperic Sigar.当我运行我的代码时,它显示错误,

这是我的代码:

package pack;

import org.hyperic.sigar.*;

public class NetworkData {
    public static void main(String[] args) {
   Sigar sigar = new Sigar();
    }

}

这是错误消息:

1 [main] DEBUG Sigar  - no libsigar-universal64-macosx.dylib in java.library.path
org.hyperic.sigar.SigarException: no libsigar-universal64-macosx.dylib in java.library.path
    at org.hyperic.sigar.Sigar.loadLibrary(Sigar.java:172)
    at org.hyperic.sigar.Sigar.<clinit>(Sigar.java:100)
    at pack.NetworkData.main(NetworkData.java:10)

我在Mac Osx Snow Leopard上开发使用Eclipse IDE for Java开发人员发现了一些旧帖子(在java.library.path中没有sigar-x86-winnt.dll)在多语言操作系统上使用Hyperic SIGAR时出错.帖子说我需要添加一些路径,如果是这样...我如何在Mac Osx中添加该路径？希望有人可以帮助^^

 # to find it later because you will need it ...
 cd ~/Downloads/

 # or whatever the latest one at the time of reading is ... 
 curl https://netix.dl.sourceforge.net/project/sigar/sigar/1.6/hyperic-sigar-1.6.4.zip

 # unpack the package to the tmp dir
 sudo unzip -o /Users/phz/Downloads/hyperic-sigar-1.6.4.zip -d /tmp/

 # copy the libsigar-universal64-macosx.dylib to your class path dir
 sudo find /tmp/ -name libsigar-universal64-macosx.dylib \
   -exec cp -v {} /Library/Java/Extensions/ \;

 # this cmd might be obsolete ... 
 # copy the sigar.jar to your class path dir
 sudo find /tmp/ -name sigar*.jar \
   -exec cp -v {} /Library/Java/Extensions/ \;

 # set you classpath dir, or add in ~/.bash_profile
 # or even better https://github.com/YordanGeorgiev/ysg-confs
 export CLASSPATH=$CLASSPATH:/Library/Java/Extensions

 # you should not see the error anymore 
 cd $my_proj_dir ; sbt compile

 # neither here .. 
 cd $my_project_dir ; clear ; sbt "test:testOnly *testClass"

首先，您需要添加Sigar.jar到您的库，然后将 .dylib 文件添加到您的库（您需要为您正在使用的操作系统选择文件）。在您的情况下，您应该添加libsigar-universal64-macosx.dylib您可以在 中找到这些文件"hyperic-sigar-1.6.4/sigar-bin/lib"。
