# 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
|
|
(Hello MSVCRT!)
|
|
- Reasonably fast CRT compared to MSVCRT and glibc, e.g. making malloc use
|
|
a faster allocator, avoid runtime checks where possible, heavely rely on
|
|
inlining.
|
|
- Extend the possibilities of C standard library with commonly used
|
|
functionality: implementing POSIX standard, capability for unicode
|
|
processing, API to traverse directories, hash functions, better strings API,
|
|
crash handlers.
|
|
|
|
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 will 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
|
|
|
|
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
|
|
|
|
Before proceeding please note that ciabatta can only be compiled and used
|
|
with `clang` and `cuik`. It may be able to work with `gcc` with some minor adjustments
|
|
but I never tested it.
|
|
|
|
You can get `cuik` in [the GitHub repository](https://github.com/RealNeGate/Cuik)
|
|
|
|
On linux you can simply run `./build.py` script. On windows can run
|
|
it with `py build.py` command.
|
|
|
|
The script accepts some command-line arguments, which you can check by running
|
|
|
|
```
|
|
$ ./build.py -h
|
|
```
|
|
|
|
## 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,
|
|
assuming you put all files mentioned above in the `./ciabatta` folder
|
|
|
|
### Compiling with ciabatta on windows
|
|
|
|
1. Add the following flags to your compilation command:
|
|
`-nostdlib -I ./ciabatta/include utf8.obj -mfma`
|
|
2. Add the following sources to the compile command:
|
|
`./ciabatta/lib/cia.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. Add the following flags to your compilation command:
|
|
- `-nostdlib -I ./ciabatta/include -mfma`
|
|
2. Link to the following libraries
|
|
- `./ciabatta/lib/cia.a`
|
|
3. Specify the ciabatta dynamic loader in linker options
|
|
- `-Wl,-dynamic-linker,lib/ld-cia.so`
