I'm currently trying to install leJOS in my Ubuntu laptop (12.04) and I've followed the instructions from here but I'm unable to build it. (http://code.google.com/p/lego-mindstorms-3d-printing-machine/wiki/SetupLeJOS)
When I type "ant" it shows the following error:
Buildfile: /opt/leJOS_NXJ/build/build.xml jlibnxt: clean: jlibnxt: BUILD FAILED /opt/leJOS_NXJ/build/build.xml:87: The following error occurred while executing this line: /opt/leJOS_NXJ/build/libnxt/build.xml:39: Can't create history file Total time: 0 seconds
Can somebody help me fix this error?
Oh and one more thing - how does one set environment paths/variables? (Which is the next step)
