"extern" in mplab

MIOS programming (C)
1

Hi guys,

im using mplab to try compile my project,

but wen i compile the project, i get an error.

here is the cause:

This explanation i found in readme of mplab c18.

Referencing a variable declared 'extern' with an initializer causes an internal failure. For example:


  extern int x = 5;

  void main (void) { x++; }


generates an internal error. The workaround is to remove the 'extern' storage class specification or remove the initializer.

what should i do???

kill me? mysys dont work, mplab dont work… i dont have more ideas.

thanks

My guess is to follow the suggestion:

  1. define the variable in the local module ie:

int x=5;

void main (void) { x++; }

OR

  1. initialise it in the module where it is defined ie. int x=5;

AND declare it (but dont initialise it) where it is used (locally) so your code would be:

extern int x ;

void main (void) { x++; }
