Embedded C Library Candidate
Locked

Thanks to Guillaume Fortaine for sending this along. Apparently a
slimmed-down newlib-based C library is now under new BSD license. For those who are debating working on or have been working on a stripped down C library for eLua, this might be of interest: http://code.google.com/p/minilib-c/ -jsnyder _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

Very cool. Now, if I can only manage to do without sleep, I'll be able to work on this. I got eLua compiling clean with minix libc, but as we all know that doesn't mean a heck of a lot.

This looks very interesting. Is the library complete, or still a
work in progress?
I was particularly interested in the malloc implementation, but saw that that malloc function simply returned 'NULL'.

Mostly interested in a malloc that is very light weight, but at
least recovers memory and performs defragmentation (the latter would
be a bonus)

Very few allocators actually defragment memory, as the runtime penalty for this operation is huge. Unfortunately, light weight and efficient (in terms of speed and/or fragmentation) allocators are still mostly an exercise in imagination.

thanks- totally understandable. I'm interested in the alloc in eLua,
will definitely check it out!
