NeTV includes the abilities to download packages that are pre-compiled from the chumby release servers.

To do local development, you will use this facility to install gcc.

WARNING -- DO NOT USE THIS PROCEDURE IT HAS NOT BEEN COMPLETELY DEBUGGED. In particular, if the device runs out of space during tool installation you can brick the device. Currently trying to figure out a more robust method for installing the very large package of tools required for development.

Preparing the device

First, connect to the network using the NeTV UI. Once you are connected to the network, ssh into the device.

Now, type the command

opkg update

This will update the list of installable packages.

Before going on, you will need to change / to be writeable. This is done by using

mount -o remount,rw /

Free up space

By default, there is not enough disk space to install the toolchain and all development libraries. Fortunately, there are a lot of unnecessary Qt packages installed. Remove them:

opkg remove qt4-embedded-examples qt4-embedded-assistant qt4-embedded-designer libqt3supporte4 --force-depends

You can also have a look at the list of installed packages using "opkg list-installed" and pick packages that you don't need.

Getting the compiler installed

Once you have freed up about 250 MB, you can run

opkg install task-sdk-native

This process will download all of the files, headers, and executables required to do C development.

Once this process is done, you can now use gcc:

gcc -o hello hello.c
./hello
Hello, world!
