There is a common problem affecting MPIDE installation under Linux. Some manual setup may be required (at least until packages with dependency information become available.) Details are available on the wiki:


Here are step by step instructions that should work for most users:

  1. Download the MPIDE tarball


  1. Untar the MPIDE tarball in a directory of your choice
tar xvzfp mpide-0023-linux-20120903.tgz
  1. Install the librxtx package
sudo apt-get install librxtx-java
  1. Add the library path to your .bashrc file
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jni
  1. Close the terminal window and open a new one (so the new library path setting takes effect)

  2. Start the MPIDE

  1. Select a directory to store sketches (pick any directory or create a new one)

  2. Observe the MPIDE GUI appears

At this point your MPIDE install should be good to go. Try a few sample sketches, and have fun! If you run into any problems, post them here and we'll try to help.

I also found that I had to install the binutils-avr package as the IDE incorrectly attempts to use the avr-size program to get the pic32 image size after linking.

The library path stuff was not needed. Seem to me if messing with paths is necessary, that something is broken.
