Responding to "torsi" on Thread " mlab / mcc variable usage problems."

@torsi

I am using mlab and mcc-18-2.40 compiler.

I find that I am unable to set initial variable values. I have declared my variables outside the scope of any C function and tried both declaring them as “static” and non-static. I have even tried declaring them local to the function.

Can you post your code so we can look at it??

I have the compiler variables options set to auto. The current state of the code has the variables declared as static at global scope and seems to allow me to change the values but I dont seem to be able to set the intial value. I have tried setting the initial value both at the time of declaration and in a function.

In ‘C’, declaring variables as static in the Global Scope, causes them to not be visible outside of functions in that Source Code file, like Private Variables in C++ Classes.

I have also noticed through attempting to debug this with printf_lib that printf on many calls becomes confused and seems to print variables in the wrong order. I am using the standard Vex Starter Code with modifications that I have made to it.

I would like to see your source code for this as well… IIRC the printf() does not support Floating Point values, so try Char’s and Int’s for your testing…

I am thinking that I have a compiler switch set stupidly or something similar.

Thanks,

I can not think of a compiler switch that would do this… What happens if you start with a “fresh copy” of the Default Code and add one Integer Variable to it and Initialize it, and printf() it??
