Getting started

Getting started may be the most challenging part of every new library. This guide is describing how to start with the library quickly and effectively

Download library

Library is primarly hosted on Github.

You can get it with:

  • Downloading latest release from releases area on Github

  • Clone master branch for latest stable version

  • Clone develop branch for latest development

Download from releases

All releases are available on Github releases area.

Clone from Github

First-time clone

This is used when you do not have yet local copy on your machine.

  • Make sure git is installed.

  • Open console and navigate to path in the system to clone repository to. Use command cd your_path

  • Clone repository with one of available 3 options

    • Run git clone --recurse-submodules https://github.com/MaJerle/lwesp command to clone entire repository, including submodules

    • Run git clone --recurse-submodules --branch develop https://github.com/MaJerle/lwesp to clone development branch, including submodules

    • Run git clone --recurse-submodules --branch master https://github.com/MaJerle/lwesp to clone latest stable branch, including submodules

  • Navigate to examples directory and run favourite example

Update cloned to latest version

  • Open console and navigate to path in the system where your repository is located. Use command cd your_path

  • Run git pull origin master command to get latest changes on master branch

  • Run git pull origin develop command to get latest changes on develop branch

  • Run git submodule update --init --remote to update submodules to latest version

Note

This is preferred option to use when you want to evaluate library and run prepared examples. Repository consists of multiple submodules which can be automatically downloaded when cloning and pulling changes from root repository.

Add library to project

At this point it is assumed that you have successfully download library, either cloned it or from releases page. Next step is to add the library to the project, by means of source files to compiler inputs and header files in search path

  • Copy lwesp folder to your project, it contains library files

  • Add lwesp/src/include folder to include path of your toolchain. This is where C/C++ compiler can find the files during compilation process. Usually using -I flag

  • Add source files from lwesp/src/ folder to toolchain build. These files are built by C/C++ compiler

  • Copy lwesp/src/include/lwesp/lwesp_opts_template.h to project folder and rename it to lwesp_opts.h

  • Build the project

Configuration file

Configuration file is used to overwrite default settings defined for the essential use case. Library comes with template config file, which can be modified according to needs. and it should be copied (or simply renamed in-place) and named lwesp_opts.h

Note

Default configuration template file location: lwesp/src/include/lwesp/lwesp_opts_template.h. File must be renamed to lwesp_opts.h first and then copied to the project directory where compiler include paths have access to it by using #include "lwesp_opts.h".

List of configuration options are available in the Configuration section. If any option is about to be modified, it should be done in configuration file

Note

If you prefer to avoid using configuration file, application must define a global symbol LWESP_IGNORE_USER_OPTS, visible across entire application. This can be achieved with -D compiler option.
