Database for C Kernel?

[xvedejas]

I'm looking for an open source (anything GPL compatible) database that might be easily ported to an all-C kernel. We've implemented a bit of stdlib already, and we're wondering if there might be a small database that could be compiled with the kernel on top of that. The one small catch is we don't want the database to use any threads or anything.

Is anyone aware of a small, simple, and efficient database software that might fit this? Thanks for any help.

We've already tried SQLite, it uses POSIX threads in numerous places, so it probably can't be ported -- that isn't to say we can't use code from it. But we really don't want to fork a project.

We ported sqlite to our kernel's C++ config module with no POSIX apart from malloc/free and a couple of string and memory manipulation functions without too much of a problem. It's handy as it supports callbacks, which we've made use of quite extensively already.

Take a look at following page:
http://www.sqlite.org/custombuild.html
There you can find porting information.

I had the same question, and I chose sqlite3, it's easy to be integrated. I followed the page that MasterLee have already posted. You can config sqlite3 to use a single thread, it's all in the link
