Creating a symlink on a FAT partition doesn't work of course, as it's an ext-only feature. But where exactly do you need this? /usr/ is on an ext2 partition, thus creating /usr/local as a symlink should be possible in all cases.

PS: I decided to let my lua.ipk install evrything in /mnt/free/_local/, with the intention to run be run from there (without symlinks in /usr/local). The install size is less than 1 MB, and my /mnt/free has 100MB free...

You're right, 1MB shouldn't harm anyone. Will have a look at Lua as soon as I have some time to. Is it as easy as Ruby, or even easier? (Now we're back on topic again )

I installed in /mnt/free, which is vfat. There are links for libraries like strudel.so -> strudel.so.1.2.3

It's nice, small and elegant. It's simple but very flexible, so it takes time to understand all features. I think it has less libraries than ruby or perl or python. The nice thing its that it is very eay to interface to existing C code. And you can program all modern cannon cameras in Lua Learn once, use everywhere. see: http://chdk.wikia.com/wiki/LUA

I've compiled libsqlite3-ruby1.8 for the iLiad. This allows you to talk to a sqlite3 database with Ruby.

• Please install sqlite3 from this post
• Next install the attached libruby1.8 ipkg. This is a temporary package and contains no data so far, but libsqlite3-ruby1.8 depends on it. In the future I will split up the Ruby package into the binary and the libraries, and this a little preparation to do so.
• Now you may install the libsqlite3-ruby1.8 ipkg.

The library uses ~250k of space and will be installed wherever you have installed Ruby. Some test code from the interactive Ruby shell:

root@ereader:/var/tmp$ irb
irb(main):001:0> require "sqlite3"
=> true
irb(main):002:0> db = SQLite3::Database.new("/tmp/test.db")
=> #<SQLite3::Database:0x402e2bac @handle=#<SWIG::TYPE_p_sqlite3:0x402daf9c>, @translator=nil, @statement_factory=SQLite3::Statement, @type_translation=false, @results_as_hash=false, @driver=#<SQLite3::Driver::Native::Driver:0x402e2b0c @busy_handler={}, @authorizer={}, @callback_data={}, @trace={}>, @transaction_active=false, @closed=false>
irb(main):003:0> db.execute("SELECT * FROM test") do |row|
irb(main):004:1* puts row[1]
irb(main):005:1> end
abc
=> nil

Have fun!
