Description
I am trying to start morpho.
I have set my Paths as such:
desktop:~$ echo $JAVA_HOME
/usr/lib/jvm/java-6-sun
desktop:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/java-6-sun/bin
but when I try to launch morpho using
./morpho-1.9.0/morpho
I get the following error
ls: cannot access ./lib/*.jar: No such file or directory
Using dynamic classpath: .:/usr/lib/jvm/java-6-sun/jre/lib/rt.jar

Could not find the main class: edu.ucsb.nceas.morpho.Morpho. Program will exit.
Not sure why this is happening, but I do have both java-6-sun and java-6-openjdk installed, and I get a similar error when setting either as the JAVA_HOME path.

need to run from morpho-1.9.0 directory.

Hi David,
Try changing into the morpho-1.9.0 directory and invoking the script from
there:
cd morpho-1.9.0
./morpho
I believe the script assumes relative paths from that directory.

I totally agree with Ben. The script should be run under morpho-1.9.0.

For what it's worth, on my linux box I keep a simple bash script named 'morpho' in ~/bin (which is on my path). I just start morpho at the command line that way, from anywhere. You'd need to tweak the paths to match your morpho install, of course:
#----------------------------------------------------
#!/bin/bash
export JAVA_HOME='/usr/lib/jvm/java-6-sun/jre'
cd /opt/morpho-1.9.0
./morpho
#----------------------------------------------------
Just remember to update it the next time you install a new morpho version and/or upgrade java!
