JAVA_HOME NOT SET WHEN INSTALL Storm

问题:

I want to install Storm in my own machine(Ubuntu 12.04 LTS) and I follow the instructions in

    https://github.com/nathanmarz/storm/wiki/Installing-native-dependencies.

When I installing jzmq, I firstly successfully perform the command

    sudo ./autogen.sh

however, when I perform

    sudo ./configure

The configuration error:

    'configure: error: the JAVA_HOME environment variable must be set to your JDK location.' 

appears.

I have set the JAVA_HOME using

    sudo gedit /etc/profile
    export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_35
    export JRE_HOME=.....
    export CLASSPATH=......
    source /etc/profile

and the output of

    echo $JAVA_HOME

is

    '/usr/lib/jvm/jdk1.6.0_35'.

I do not know why the error happens, anyone knows it? Thanks a lot.

############################################################################### Here I give my way to solve the problem:

1. Open configure in jzmq folder

   sudo gedit configure
   

2. Find codes bellow:

   # Check for JDK
   if test "x$JAVA_HOME" = "x"; then
       as_fn_error $? "the JAVA_HOME environment variable must be set to your JDK location." "$LINENO" 5;
   fi
   

3. set JAVA_HOME here:

   # Check for JDK
   export JAVA_HOME=/usr/lib/jdk1.6.0_35
   echo $JAVA_HOME
   if test "x$JAVA_HOME" = "x"; then
       as_fn_error $? "the JAVA_HOME environment variable must be set to your JDK location." "$LINENO" 5;
   fi
   

4. This method can solve my problem, maybe it is useful for you.

Hit the same issue among others while installing JZMQ as part of Storm 0.82 install a couple of months back. Solved this problem by doing exactly what you outlined above. There were some other gotchas for JZMQ. Copying my INSTALL steps and hopefully they'll be useful.
