When compiling...

Following warnings are shown:

C:/Program Files/C2000 Code Generation Tools 5.1.1/include/math.h", line 27: warning: type qualifiers are meaningless in this declaration

C:/Program Files/C2000 Code Generation Tools 5.1.1/include/math.h", line 40: warning: type qualifiers are meaningless in this declaration

The prototypes (in math.h) are:

double far_modf(double x, far double *y);
double far_frexp(double x, far int *exp);

In our app this results in a total of 26 warnings which is quite annoying.

If you build for large model (-ml) then the far qualifier doesn't do anyththing. All 28x code should be built for large model.

You can get the warning error number by using the --display_error_number option and then supress it by using --diag_suppress=num.

Thanks Lori. :D

However, supressing compiler warnings is evil.

Wouldn't it be better to make sure that libraries that ship with CGTs do not produce warnings?
