fenlibc - Fenix Standard C Library
|
|
|
|
|
==================================
|
|
|
|
|
|
|
|
|
|
fenlibc is a standard C library used by Fenix. This library follows the ISO C
|
|
|
|
|
and POSIX standards and is reasonably portable across UNIX and UNIX-like
|
|
|
|
|
systems, though it may not be suitable as a drop-in replacement for the C
|
|
|
|
|
library that exists on such a system.
|
|
|
|
|
|
|
|
|
|
Currently, the following headers are finished and fully compliant:
|
|
|
|
|
assert.h*
|
|
|
|
|
cpio.h
|
|
|
|
|
errno.h?
|
|
|
|
|
iso646.h
|
|
|
|
|
libgen.h
|
|
|
|
|
limits.h?
|
|
|
|
|
stdbool.h

|
|
|
|
|
ulimit.h

Building
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
Currently, fenlibc can be built as part of a standard Fenix ISO through its
|
|
|
|
|
makefile. To do so, simply run Fenix's build.sh script. It could use alterations
|
|
|
|
|
to allow its C library to be build to an existing system. If you'd like to
|
|
|
|
|
help out, that's a good place to start!
|
|
|
|
|
|
|
|
|
|
Portability
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
Currently, fenlibc has yet to be tested on any existing UNIX{,-like} systems.
|
|
|
|
|
If you have any luck getting it up and running on a UNIX{,-like} system,
|
|
|
|
|
let us know!
