how to ignore deprecated warning

[applemax82]

hi,

The icc version that I use is 'icc (ICC) 14.0.2 20140120' in linux.

Some elements in some structs are declared as deprecated. Some functions will use those deprecated elements.

For example, __attribute__((deprecated)) int *val;

If gcc is used, the following preprocessor lines can turn off and on 'deprecated warning'

#pragma GCC diagnostic ignored "-Wdeprecated-declarations"

#pragma GCC diagnostic warning "-Wdeprecated-declarations"

If icc is used. how to turn off and on 'deprecated warning' in source code, but not in compiling flags.

Thanks!

Regards

You could use pragma warning with the diagnostic number instead, i.e.:

#pragma warning (disable:1478)

void foo() {
  val = 0; // uses deprecated varable
}

#pragma warning (enable:1478)

Thanks for your help.

I have another question. Is there some micro definition with which to differentiate between GCC and ICC compiler?

Thanks

Yes.

You may want to bookmark https://sourceforge.net/p/predef/wiki/Home/.  It's a great resource for answering that type of question (the second one, not the first).  Second only to https://graphics.stanford.edu/~seander/bithacks.html on my list of favorite C/C++ resources (though the former is generally slightly more useful).
