Eclipse CDT does not index code between #if SYMBOL #endif

I am working in webkit with Eclipse CDT as IDE, there are some classes under #if ENABLE(VI开发者_Python百科DEO) but eclipse does not index it. It thinks that they are unused blocks, is there any way by which I can tell eclipse to index everything?

Not sure about the solution you suggested, but there's another:

Open your project's properties, go to C/C++ General -> Path and Symbols -> Symbols, make sure you have Configuration set to All configurations and then add there any preprocessor symbols you'd like to have defined.

Please check

If you for example have problems in indexing "#if DEBUG" then the indexing result will depend on how DEBUG is defined.

This really depends on the definition of the DEBUG macro:

#define DEBUG ---> // syntax error (#if with no expression)

#define DEBUG 1 ---> // ok, selects if-branch (#if 1)

#define DEBUG 0 ---> // ok, selects else-branch (#if 0)

#undef DEBUG ---> // ok, selects else-branch (#if DEBUG)

You should probably use #ifdef DEBUG instead.

Or you can define DEBUG = 1.

Go to Project --> Settings --> C/C++ General --> Preprocessor Include --> Entries.

Under "Setting Entries" select "CDT User Setting Entries".

Then "Add..."

Then select "Preprocessor Macro" and add the name and value.
