Install maple-ide on 64 bit linux

The maple IDE is only offered as 32Bit java binary/bytecode. On a 64Bit linux with a default java installation maple-ide will refuse to start with the following error:

$ ./maple-ide 
java.lang.UnsatisfiedLinkError: /mnt/aaa/bin/maple-ide-v0.0.12/lib/librxtxSerial.so: /mnt/aaa/bin/maple-ide-v0.0.12/lib/librxtxSerial.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) thrown while loading gnu.io.RXTXCommDriver

You will be able to select a folder for your sketches and then the application will crash.

The problem can be solved by installing the 32Bit version of Java (i chose the sun/oracle one):

$ sudo apt-get install ia32-sun-java6-bin

Then modify the startup script maple-ide to point to the appropriate java installation. Adjust JAVA_HOME and the PATH environment variables:

#!/bin/sh
APPDIR="$(dirname -- "${0}")"

cd $APPDIR

# /usr/lib/jvm/ia32-java-6-sun/jre/bin/
export JAVA_HOME=/usr/lib/jvm/ia32-java-6-sun/jre
export PATH=$JAVA_HOME/bin:$PATH

for LIB in \
    java/lib/rt.jar \
    java/lib/tools.jar \
    lib/*.jar \
    ;
do
    CLASSPATH="${CLASSPATH}:${APPDIR}/${LIB}"
done
export CLASSPATH

LD_LIBRARY_PATH=`pwd`/lib:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH

export PATH="${APPDIR}/java/bin:${PATH}"
