title: Member declaration not found
body: <p>I have worked on a C++ project using a regular text editor. Later, I imported all the files to Eclipse to make it debugging easier. </p>
  
  <p>In Eclipse a weird thing happens. It complains "Member declaration not found" even if I have included the header file. The header file has the function definition. </p>
  
  <p>How do I fix this problem?</p>
