Hello everyone,
I am trying to get ImageJ to compile a plugin on Linux and cannot find
how to set my Java environment properly.
I start ImageJ from the command line with something like:
java -jar ij.jar -ijpath path/to/plugins/
When I try to compile my plugin I get a message saying:
"This JVM does not include the javac compiler
...
[OK]
"
while it does:
$ which javac
/usr/bin/javac
$ readlink -f $(which javac)
/usr/lib/jvm/java-6-sun-1.6.0.13/bin/javac
This installation is Sun's Java on Ubuntu.
When I start ImageJ with an explicit classpath
java -cp /usr/lib/jvm/java-6-sun-1.6.0.13/lib/
tools.jar:ij.jar ij.ImageJ -ijpath path/to/plugins/
it works.
But I would prefer if it worked with a simple command line and by
setting environment variables (the code in which I call ImageJ should
work cross platform when the user set's the environment correctly).
Setting
JAVA_HOME to /usr/lib/jvm/java-6-sun-1.6.0.13/
CLASSPATH to /usr/lib/jvm/java-6-sun-1.6.0.13/lib
or even
CLASSPATH to /usr/lib/jvm/java-6-sun-1.6.0.13/lib/tools.jar
and using
java -jar ij.jar -ijpath path/to/plugins/
or
java -cp ij.jar ij.ImageJ -ijpath path/to/plugins/
does not work.
Could someone point me towards the correct configuration please?
PS: as a side note, is there a way to compile plugins on the command
line, outside of ImageJ.
Thanks in advance.
JiHO
