As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

.. _external_library: External Library ################# Overview ******** A simple example that demonstrates how to include an external static library into the Zephyr build system. The demonstrates both how to build the external library using a different build system and how to include the built static library. Windows Note ************ To use this sample on a Windows host operating system, GNU Make needs to be in your path. This can be setup using chocolatey or by manually installing it. Chocolatey Method ================= Install make using the following command: .. code-block:: bash choco install make Once installed, build the application as normal. Manual Install Method ===================== The pre-built make application can be downloaded from https://gnuwin32.sourceforge.net/packages/make.htm by either getting both the ``Binaries`` and ``Dependencies`` and extracting them to the same folder, or getting the ``Complete package`` setup. Once installed and in the path, build the application as normal.
