Supported Combinations

Steps to Run the Example

Sample Output

Shown below is a sample output when the application is run,

Hello World!

C++ Build Details

In this example the "hello_world.cpp" and "main.cpp" files are built with the c++ compiler flags. The example will link with the prebuilt mcu sdk libs.

Flags used for c++ build

Below are the flags used for the files to build with c++ flags along with the other flags used for c files.

  • -x c++
  • -Wno-c99-designator
  • -Wno-extern-c-compat
  • -Wno-c++11-narrowing
  • -Wno-reorder-init-list
  • -Wno-deprecated-register
  • -Wno-writable-strings
  • -Wno-enum-compare
  • -Wno-reserved-user-defined-literal
  • -Wno-unused-const-variable

Building the mcu sdk libs with c++ flsgs.

The pre built libs provided in mcu sdk are built with the c flags. However the application can re build the libs using the c++ flags. The application needs to pass the below additional flag for the make commands used for building libs


note: Before re building the libs you need to clean all the pre built libs.

Building an application using c++ flags

Hello world cpp example is provided as referance to building application using c++ flags. If you want to build the application using the c++ flags please refer the makefile In the makefile the files with extn .cpp are compiled with the c++ flags and files with .c extn are compiled with c flags.
