If you use CodeBlock for compelling C/C++ programs you might face this kind of warning . suppose, if you got warning such as “implicit declaration of function ‘exit’ “ that means you need to include header file #include before you use exit function in any program. for example, consider below program

Implicit function declaration This usually indicates that the header file that declares this subroutine was not #included. When a subroutine is used without having been declared, many C and FORTRAN compilers generate an implicit declaration as "function returning integer."

But It is not declared before main. The 1999 standard did away with implicit int, so compiling with -std=c99 -Werror should catch any implicit declarations. – John Bode Apr 18 '16 at 17:36 This is interesting.

You tell the compiler the function is valid by a)coding the function before you call it the first time or b)using a function prototype if the code for the function does not appear before the first call. implicit declaration of function serzh over 3 years ago i have project app_ble_uart and i want add to it functin read from mpu6050 i add to Makefile Makefile pathes and add #include "mpu6050.h" and InitMPU6050(0x68); into main main.c but i have error STM32 core support for Arduino.
