wrap_lz4

wrap_lz4 is an Eiffel binding of lz4 API using WrapC tool.

lz4 is Extremely Fast Compression algorithm.

Requirements

• WrapC tool.
• lz4 API Extremely Fast Compression algorithm

Download and Install

Linux

Building LZ4 - Using vcpkg

You can download and install LZ4 using the vcpkg dependency manager:

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
vcpkg install lz4

Then copy the header files to /usr/local/include

cd vcpkg/installed/x64-linux/include
cp lz4*.h /usr/local/include

and the library to /usr/local/lib

cd vcpkg/installed/x64-linux/lib
cp liblz4.a /usr/local/lib

If you use other configuration, be sure to update the Library configuration scripts and the eiffel configuration file with the specific locations to the headers and lib.

Windows

Using vcpkg (https://github.com/microsoft/vcpkg) tool, you can install lib lz4 library

vcpkg install lz4:x64-windows

Copy the lib lz4.lib to $ECF_CONFIG_PATH/C/lib, be sure to have in the path the DLL lz4.dll

Status

Work in progress

Examples

• simple_buffer Example program to demonstrate the basic usage of the compress/decompress functions..

How to compile the C library glue code.

Before to use the examples you will need to compile the C glue code, go to

library/generated_wrapper/c/src 

and run

finish_freezing --library

It will copy the C lib eif_libz4.a to $ECF_CONFIG_PATH/C/spec/$(ISE_PLATFORM)/lib/ or eif_libz4.lib to $ECF_CONFIG_PATH/C/spec/$ISE_C_COMPILER/$ISE_PLATFORM/lib
