问题
I am looking for suggestions for a data store written in C that will compile for ARM Cortex M3 without any operating system.
I want it to be:
- written in C
- preferably free and/or open source
- able to be compiled with GCC
- works on bare metal processor without operating system or file system support
It can be SQL or not. I would like something like MongoDB that is compatible with with JSON (i.e. can serialize via JSON in plain C char buffers.)
The needs of the datastore would be to manage data in RAM from a fixed allocation of memory. No "dynamic" allocation (i.e. no malloc).
回答1:
SQLite3 is a very good contender, but if you a just looking for a small and simple key/value store the you should also look up gdbm.
