Re: undefined symbol: sqlite3_open

[Pedro Aguilar]

Hi Rob,

SQLite3 is definitely a cheap alternative from the resources point of 
view, specially if you only have one or very few processes that access 
the database. In gnokii it seems that other backends are more tested.

In the system in which I'm working we started with just a couple of 
processes, but now we have many processes that write and read to the 
same database and SQLite3 seems not to be the best option any more...

I tried PostgreSQL but it refused to run with less than 256MB. I managed 
to run MySQL with only 13MB so it could be a good alternative for 
handling multiple write/read processes even if I only have 64MB in my 
system.

I'm not a fan of Allwinner neither, but I've found several low-price ARM 
alternatives, but it depends on what you're doing.

Regards,
