Hello. I am trying to find new and exciting ways to optimize (read: shrink down) my current code and want to include an eeprom autorefresh option to cut down on variables. Basically, when I have the AutoRefreshCompile option set, I want it to create the variable "randomvariable". My code is pretty simple:
#define AutoRefreshCompile 1 #if(AutoRefreshCompile==1) { // line x extern signed short randomvariable; } // line y #endif
I am getting errors that read as follows:
VARS.H(x) error C141: syntax error near '{' VARS.H(y) error C141: syntax error near '}'
I'm guessing it is not possible to do this (if I remember correctly, variables have to be declared at the beginning and can't be in the middle of functions/code segments but maybe it's some really simple fix.
I realize this might not work but I figure it's worth a shot. Any suggestions? Thanks!
In the primary post the error message is:
The file name VARS.H implies it is a header file. Header files should not contain code, so your snippet:
is (I assume, because I can't know) not part of a function code but part of a declaration.
If this is true then of course the { and } are not allowed, simply write:
#define AutoRefreshCompile 1 #if(AutoRefreshCompile==1) extern signed short randomvariable; #endif
or something like that...
#define AutoRefreshCompile #ifdef AutoRefreshCompile extern signed short randomvariable; #endif
If this is not true, ignore my answer.
