## Introduction Liberasurecode is an erasure code library which can support multiple erasure code 'backends'. The repository includes a Jerasure for Reed-Solomon implementation. [TODO: flesh this out a bit more] ## Code organization ``` ├── README ├── NEWS ├── COPYING ├── AUTHORS ├── INSTALL ├── ChangeLog | ├── autogen.sh ├── configure.ac ├── Makefile.am | ├── include │ ├── erasurecode │ │ ├── erasurecode.h --> liberasurecode frontend API header │ │ └── erasurecode_backend.h --> liberasurecode backend API header │ └── xor_codes | ├── src │ ├── erasurecode.c --> liberasurecode API implementation | | (frontend + backend) │ ├── backends │ │ └── xor │ │ └─── flat_xor_hd.c --> 'flat_xor_hd' erasure code backend | | implementation | | │ ├── builtin │ │ └── xor_codes --> XOR HD code backend, built-in to | | | liberasurecode │ │ ├── xor_code.c │ │ └── xor_hd_code.c | | │ └── utils │ └── chksum --> fragment checksum utils for erasure │ ├── alg_sig.c coded fragments │ └── crc32.c └─── test --> Test routines ├── builtin │ └── xor_codes ├── liberasurecode_test.c └── utils ``` ## Dependencies ## Build To build the liberasurecode repository, perform the following from the top-level directory: `$ ./autogen.sh` `$ ./configure` `$ make` `$ make test` `$ sudo make install`
