Is it possible that eclipse ide is mistakenly showing this error while it compiles it fine?
How can I fix this?

    Try to delete that problem marker from the problems view and rebuild your project (entirely, not just an incremental). If that fixes the issue, than it was simply an inconsistent state of the compiler.

    However, if it does not fix the problem, then it is possible that the Eclipse editor uses a different parser (for content assist, etc.), that cannot handle something your compiler can. For this case, I would look around the C/C++ editor preferences related to errors, maybe it is turnable off (however, I don’t program C/C++, so I cannot tell you what to look for).
