Try next example.
1.Create new Quote sample project(Quote1). Open quote.cc file. All includes in
this file are known to our parser.
2. Change Default Compiler collection property in Tools/Options/C/C++ to Sun
3. Create new Quote sample project(Quote2). Open quote.cc file. cstdlib and
cstring libraries were not included to Sun compiler collection include
directories. So they marked as unknown.
4. Change compiler collection for quote2 project to GNU compiler collection.
Project were not reparsed. cstdlib and cstring still unknown. But if to close
Quote2 project and open again it will be reparsed and all inclusions in quote.cc
becomes known as for Quote1.
works for me.
