Linking with a static library

#############################

This sample shows how to link a static library to a Zephyr application.

A sample library is also included.

Read mylib/Makefile to discover how to use the Zephyr's toolchain

to build a static library.

If the library's source code is available, perhaps it could be more

easier to integrate that source code to your application than creating

the static library.

Build instructions

==================

1. It is assumed that ZEPHYR_GCC_VARIANT and ZEPHYR_SDK_INSTALL_DIR

variables are already set. See:

https://www.zephyrproject.org/doc/getting_started/getting_started.html

2. source $ZEPHYR/zephyr-env.sh

   Where $ZEPHYR points to the directory that contains the zephyr

   repository.

3. make

4. make run

subdir-ccflags-y += -I$(SOURCE_DIR)/../mylib/include

obj-y += src/
