Ubuntu下Subclipse报failed to load javahl library的解决办法

2011-09-01, Nortan Posted in Java, usefulness, OS | 我来说两句 | 查看全文>>

最近买了一T61p,买回后直接安装Ubuntu 10.04,安装Eclipse并安装Subclipse1.6x插件后,使用svn过程中报
Failed to load JavaHL Library. These are the errors that were encountered: no libsvnjavahl-1 in java.library.path no svnjavahl-1 in java.library.path /opt/local/lib/libsvnjavahl-1.0.0.0.dylib: no suitable image found. Did find: /opt/local/lib/libsvnjavahl-1.0.0.0.dylib: mach-o, but wrong architecture
原来是缺少一些关联文件,去subclipse的Wiki看了看,说需要安装libsvn-java,在Ubuntu 下安装很简单,命令如下:

sudo apt-get install libsvn-java

安装完后,这文件在/usr/lib/jni目录下,这个目录并不是eclipse的java.library.path路径之一,所以还需要修改eclipse.ini来告诉eclipse去哪找这个libsvn-java相关的文件.
打开eclipse.ini,在最后行加入如下内容(注意换行)

-Djava.library.path=/usr/lib/jni

1.Preflight information

First we need to create the RoR application.

rails cron
cd cron
script/generate model my_model
vi config/database.yml (set the database username/password, and databases created in your environment)

2. Creating the rake task(s)

2.1 Simple task

First lets see how to call any ruby code from rake. Rake code is placed in lib/tasks/FILENAME.rake. So lets create a lib/tasks/cron.rake and place this code in it: 查看全文…
