买了一块讯为的开发板，这几天在做环境的搭建。讯为提供搭建环境的资料很少，如果使用他们提供的Ubuntu12.04.2平台应该就没什么问题了。
在执行脚本install-sun-java6.sh时出现一些问题。
这个他们提供的脚本里的内容：
#!/bin/sh
#
# Download Sun JDK 6 from:
# http://www.oracle.com/technetwork/java/javase/downloads/index.html
# Java SE Development Kit 6 Update 43
#
# You can download it by browser
# http://download.oracle.com/otn-pub/java/jdk/6u43-b01/jdk-6u43-linux-x64.bin
# wget doesn't work
#
chmod +x jdk-6u43-linux-x64.bin
./jdk-6u43-linux-x64.bin
mkdir -p /usr/lib/jvm
mv jdk1.6.0_43 /usr/lib/jvm

这是我修改后的内容：
#!/bin/sh
#

这里主要不同是：
jdk-6u43-linux-x64.bin
改成了
jdk-6u43-linux-i586.bin
这文件可以在网上下载下来，在目录中替换掉jdk-6u43-linux-x64.bin就行。
update-alternatives --install "/usr/lib/mozilla/plugins/libjavaplugin.so" "mozilla-javaplugin.so" "/usr/lib/jvm/jdk1.6.0_43/jre/lib/amd64/libnpjp2.so" 1
改成了
update-alternatives --install "/usr/lib/jvm/jdk1.6.0_43/jre/plugin/i386/ns7/libjavaplugin_oji.so " "mozilla-javaplugin.so" "/usr/lib/jvm/jdk1.6.0_43/jre/lib/i386/libnpjp2.so" 1
这里的路径要根据自己的ubuntu来改写。不懂路径可以收索文件来找路径。
出现这些错误的原因是讯为脚本是对64位ubuntu编译环境写的，而我的ubuntu是32位。
