Type GObject could not be resolved [message #1823835]

After I created a Makefile project to play around with glib and GObject I'm having this issue. Eclipse shows that GObject could not be resolved, when the header file

#include <glib-2.0/glib-object.h>

for it is resolved. here is the screenshots

index.php/fa/37733/0/

I also able to go by link and open glib-object.h header file in eclipse, so I assume it resolved,

index.php/fa/37734/0/

as well as I'm able to build the project using eclipse, here is my makefile:

index.php/fa/37735/0/

Could someone point me what I'm doing wrong or how it can be resolved?

You have to tell two different things where your headers can be found:

the compiler via the makefile
the CDT Indexer

They are independent.

To do (1) Set the include path for each compiler at:
Project --> Properties --> C/C+ Build --> Settings --> Tool Settings tab --> <compiler> --> Includes
This only works when Eclipse is generating the Makefile.

To do (2) Set the include path as a User Entry at:
Project --> Properties --> C/C++ General --> Preprocessor Include Paths, Macros etc. --> Entries tab --> <language>

You can do both with:
Project --> Properties --> C/C++ General --> Paths and Smbols
but you need the CDT Managed Build Settings provider enabled in
Project --> Properties --> C/C++ General --> Preprocessor Include Paths, Macros etc. --> Providers tab

I tried to check your suggestion, but at first point I found that my project settings doesn't contain C/C++Build entry, than I compared it with another project in my workspace that doesn't use glib and works fine, and I found that it has C/C++Built entry in project properties. So I checked the project nature and found this

index.php/fa/37741/0/

The reason why is that so it's because I created project using Makefile configuration which is stated as Experimental

index.php/fa/37742/0/

So I recreated the project as C/C++ Managed Build and than mentioned by you properties appeared.

index.php/fa/37743/0/

But the initial problem still presents. I don't know, maybe I miss something, but to me it looks like all tools is set and includes are in place.

I've had similar problems with glib.
Sometimes just rebuilding the index works.
Sometimes it just takes time.

I know. Not much help.

As for Makefile Projects, I import the code instead of starting a new project.
File --> Import --> C/C++ --> Existing Code as Makefile Project
