Ciabatta

Ciabatta - An implementation of cross-platform C standard library with the following goals:

• Providing C standard library that fully implements all C features. Some standard libraries lack many features of C11 and C23, like threads.h or aligned_alloc in case of msvcrt.
• Making standard library that is easy to port to other platforms, for example an embedded platform or a custom operating system.
• Allowing applications to debug and step into standard library functions
• Reasonably fast CRT compared to MSVCRT and glibc.
• Extend the possibilities of C standard library with commonly used functionality: implementing POSIX standard (including directories and sockets), capability for unicode processing.

Ciabatta is not binary-compatible with other CRT libraries. That means that any libraries that your project uses have to also be compiled with Ciabatta, otherwise you might run into issues.

Please note that as of today ciabatta is still during development and does not implement many of the features that need to be implemented. Using it at current time is discouraged.

Support

Operating System:

• Windows
• Linux (planned)

Processor Architecture:

• x86-64

This library is supposed to be extensible to other platforms, meaning that you can write an OS layer for another OS and use the rest of the CRT functionality.

Building ciabatta

Building ciabatta with MSVC is not supported. The only compiler that the library have been compiled and tested with is clang.

Note that the library can only be used with clang

Building on windows

Run ./build.ps1 to compile ciabatta

• (Optionally) Run ./test crt to make sure there are no errors

Building and using on linux

There are two options: Use ciabatta as a shared library or as a static library.

Run ./build.sh to compile ciabatta

• If you wish to use shared library instead add -shared option to the build script

Usage

Grab the following files into your project's (or any other) directory:

• The ./include folder
• The .lib folder
• (Windows only) The utf8 folder

In order to compile your project with ciabatta see the following sections

Compiling with ciabatta on windows

1. Add the following flags to your compilation command: -nostdlib -I ./include utf8.obj -mfma
2. Link to the following libraries: -l ./lib/ciabatta.lib

Note: The include folder refers to the folder you copied from ciabatta. Set the path to it accordingly.

Compiling with ciabatta on linux

1. In case of static linking:
2. Add the following flags to your compilation command: -nostdlib -static -I ./include
3. Link to the following libraries ./lib/ciabatta.a
4. In case of dynamic linking:
5. Add the following flags to your compilation command: -nostdlib -no-pie -I ./include
6. Link to the following libraries: ./lib/ciabatta.so ./lib.ctors.o ./lib.entry.o
