Rule 8.6: External declaration without definition - Polyspacer - 16-06-2015 I have a header file MISRA_8.6.h, in which a variable is declared: Code: extern signed short int Variable; And I have the corresponding c-file MISRA_8.6.c, which uses the variable as input. Code: #include "MISRA_8.6.h" The c-file defining the variable is out of scope. Is rule 8.6 violated by this setting or is another rule 8.x violated? Re: Rule 8.6: External declaration without definition - misra-c - 25-06-2015 Rule 8.6 covers the situation when there is no external definition present in the set of files being analysed. Therefore "Variable" will violate rule 8.6. |
