error: extra qualification ‘Item::’ on member ‘Item’

Today I download some fp growth source code from some site.

and compile them and got this error.

error: extra qualification ‘Item::’ on member ‘Item’.

I think it may cause by new compiler didn't want Item:: (class meaning)ahead of Item (function meaning).

Weird about libstdc++.so.5 Error

Yesterday , I try to setup Hadoop on eclipse on Ubuntu in Virtual Box.

I found Error about Missing some class. It say
"BUILD FAILED
build.xml :316: Unable to find a javac compiler
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/usr/lib/jvm/java-6-openjdk/jre"
".

First , you should download JDK from sun micro system and install it's packages.
Don't forget to "chmod +x " if you can't run install command.
or you may can "sudo apt-get install " that something I don't know too.

if you encounter problem about
"./java_ee_sdk_linux.bin: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory"
or similar to this you may get the wrong .bin file.
Try to download Other file that not the same as old one.

If you got the right .bin file now. Don't forget to "chmod +x " if you can't run install command.
then run "./".
Additionally , you may move the JDK folder to the well-manner category "/usr/lib/jvm".
(If you can't use copy command then omit it. use move instead it then finish successful.)

After you finish install jdk then do the last step to let's Ant correctly run.

Lastly , Add tools.jar to Ant Runtime Classpath.The Problem solved.

many things occur yesterday. As I re-start learning flash action script 3.
most occur error is this error.

ReferenceError: Error #1056: Cannot create property firstmon on mike.map1.

at flash.display::MovieClip()
at mike::map1()

other thing I learned. I will write other day. maybe after my project rather finish.

this problem always occur when you did not declare variable in document class.
to solve this problem.
you should declare variable as many as you define object name in .fla file.
and don't forgot declare these variables to public.

for example
I have movie clip name "firstmon" in fla file.
and I map this fla with this class
I the class I should declare definition for firstmon to solve error.

think I should help you. thx.
