Eclipse call hierarchy skips calls in undefined #ifdef regions

Question

Hi all,

The "call hierarchy" and "declaration" features in Eclipse CDT omit results that exist in undefined (greyed out) #ifdef regions.

Example:

void blah(void) {
#ifndef ABC  
   foo();
#else         //line is greyed out
   bar();     //line is greyed out
#endif        //line is greyed out
}

The call hierarchy for foo() will list blah() as a caller; the call hierarchy for bar() will not list blah().

I'm not expecting it to do full resolution of which #define blocks will get compiled, I simply would like it to return all calls/declarations of the function I'm searching for, regardless of the #define blocks that surround it.

Other IDEs such as SlickEdit are able to do this.

Does anyone know of a way to get Eclipse to adopt this behavior?

Thanks.

Answer 1

There are many "bugs" opened on the CDT "Call Hierarchy" feature:

• Open call hierarchy doesn't work for constructors.
• Calls to implicit constructors missing
• Call graph for constructors does not work for member variables.

All of them are linked to the binding resolution (also the situation will improve for implicit constructor calls in CDT7.0).
And since bar() is clearly within an Unreachable #ifdef block, chances are the "binding resolution" will ignore it completely.
Hence the incomplete cal hierarchy.

VS2010 presents anew future called Call Hierarchy of Methods that provides you with a tree view at design time

This tree view contains all (methods, prop., or whatever called the method) that calls the applied method

here is how try that in VS2010.
