#Ifdef access code in eclipse

Question

if code:

#ifdef ABC code(); #endif 

I want to access function code () using Open Declaration. How can I do this without defining ABC in the source code.

Answer 1

You can take a look at this entry. How can I get Eclipse to index the code inside #ifdef ... #endif

Regarding .h files, make sure Indexer is installed to index header files that are not Project-> Properties-> C / C ++ General → Indexer, and check "Index source files not included in the assembly" and (possibly) "Index unused headers as C files."

Answer 2

It actually worked for me. You have many weird makefiles throughout the project.

Project → Properties → C / C ++ General → Path and Symbols → Symbols Tab → Add ...

Disable Show built-in values ​​to avoid confusion. Make sure the correct assembly configuration is set above.

Click Apply ...

You will find out that this worked if it asks you to rebuild the index.

Answer 3

Go to "Project / Properties ..." to open the configuration for your project.

After that, go to "C / C ++ Build", then "Build Variables". Then add the variable "ABC".
