Eclipse CDT: Why Can\'t I Resolve the \'cout\' Symbol, Even With Included Headers?

Eclipse CDT: Symbol 'cout' Could Not Be Resolved

This error can occur when compiling C code in Eclipse CDT, even if the necessary header files are included. The issue may lie with missing include directories in the project settings.

To resolve this issue, perform the following steps:

1. Right-click on the project in the Package Explorer and select Index -> Search For Unresolved Includes.
2. Eclipse will generate a list of unresolved includes.
3. Check the /usr/include directory for any missing directories corresponding to the unresolved includes.
4. Add any missing directories to the C Include Paths and Symbols section in the Project Properties.
5. Rebuild the index by selecting Index -> Rebuild.

In the specific case mentioned in the original post, it was suspected that the /usr/include/c /4.6/x86_64-linux-gnu directory was missing from the include paths, causing bits/c config.h to remain unresolved. After adding the missing directory and rebuilding the index, the issue was resolved.

Remember that the specific missing directories may vary depending on the system and the headers being used, so it may be necessary to search and add additional directories as needed.
