A.4. Saving Space on the Target

The newly installed image running on the KuroBox consumes 115.4 MB of disk space (according to df -h). This isn't bad, but it is actually quite large. There are a number of files that can be removed from the distribution if you need more space, or just want to see how small you can make things go.

For starters all the *.a files in the various lib directories are all only necessary when compiling code (and even at that, they're only necessary if you're specifically statically compiling your binaries). Since the development PC can be used to compile your KuroBox applications these files really aren't necessary on the target. If you compile in your development PC, you'll also not need the include directories.

There are many other things. For example you can prune what you don't need from the Busybox executable. If you aren't going to be running Fortran, Objective-C, or C++ applications you can remove their support libraries too. You probably don't need the info files.
