It comes with pre-built +electronics, and pre-installed firmware. But I like being able to do +upgrades, especially since the whole thing is still maturing. + +So, the `MakerBot instructions`_ say "get the Arduino_ env, apply the +Sanguino_ patch, and you're done". Easy, right? + +I start by downloading the sources for the Arduino_ software. You see, +I run a 64-bit machine, and the pre-built Linux binaries are 32 +bits. Not good enough. + +Then, following the `Arduino instructions`_, I say:: + + ~/arduino-src/build/linux$ ./make.sh + +and it goes:: + + The Java bundle that is included with Processing supports only i686 by default. + To build the code, you will need to install the Java 1.5.0_15 JDK (not a JRE, + and not any other version), and create a symlink to the directory where it is + installed.

By having mis-read the notice, I actually symlink the +``icedtea6`` JDK. It didn't seem to mind. + +Now it builds, but it won't run: there are 32-bit libraries! Who built +them?? + +Looking at Portage (yes, I run Gentoo) I see that there is an ebuild +for an (older) Arduino version, and it declares dependency on exactly +the library that is giving me problems.

Of course the Arduino program won't use +it (it's not in the default ``CLASSPATH``), so I symlink it over the +bundled version:: + + rm work/lib/RXTXcomm.jar work/lib/librxtxSerial.so + ln -s /usr/share/rxtx-2/lib/RXTXcomm.jar work/lib/ + ln -s /usr/lib/rxtx-2/librxtxSerial.so work/lib/ + +It runs! + +Of course, no Sanguino_ support, and the CupCake_ main board is a +Sanguino_. + +The `Sanguino instructions`_ say to add a couple of directories, +overwrite a few files, add some lines to a file, and it should be +enough.
