I have a project which use gcc -include file.h

As gcc documentation say, this ensures that file.h is included in every file which is compiled this way (meaning like there was #include "file.h" in every other files).

Now I have imported this project into eclipse and I set up the include path where that file is but can't figure out how to do something like gcc -include in eclipse project setting. The result of this is that in editor I have a LOT of "Symbol xy could not be resolved" but the project compiles just fine.

Thanks for any help.

  • So you just need file.h seen from the indexer? I think that can be done adding the header file in the Paths and Symbols properties dialog, but I'm not sure if you can add a specific file. Commented Jan 13, 2016 at 10:00
  • I tried that but it did not help, I think that Paths there are equivalent of gcc -Ipath. Yes I need only that file.h to be seen from indexed. Also I tried setting indexed to index all header (because the file.h is in path I have added in the Paths and Symbols) but that also did not helped. Commented Jan 13, 2016 at 10:10

You can change the CDT GCC Built-in Compiler Settings on a project-by-project basis.

  • Go to Project -> Properties -> C/C++ General -> Preprocessor Include Paths, Macros etc.
  • Select the Providers tab.
  • Select CDT GCC Built-in Compiler Settings
  • Unselect Use global provider shared between projects
  • Add the required GCC flags to the Command to get compiler specs: input box

(see highlighted text in image below)

For completeness, the more direct way would be to just add file.h to the Paths and Symbols properties dialog / Include files tab.
