turning off warnings

Hi,

Well, I do not want to turn off ALL warnings. I want to turn off those that I do not want to see.
For instance, for the following (perfectly valid) statement:

assert( one == 1 && "One is not 1");

pgCC generates:

warning: controlling expression is constant

Is there any way I can turn this off?

thanks

Hi slyi,

You can do this with the “–diag_suppress” flag.

% cat warn.cpp
void foo () {
    if("One is not 1");
}

% pgcpp --display_error_number -c warn.cpp
"warn.cpp", line 2: warning #236-D: controlling expression is constant
      if("One is not 1");
         ^

% pgcpp --diag_suppress 236 -c warn.cpp

Also, the pragma “#pragma diag_suppress 236” will work as well.

%cat warn.cpp
void foo () {
#pragma diag_suppress 236
    if("One is not 1");
}

% pgcpp -c warn.cpp
