Created attachment 141065 [details] Thoroughly confused IDE SUMMARY Can you guys sit down an intern for a week and tell her to actually test every last one of the project templates you ship with KDevelop? It's ridiculous that a project created using one of the templates builds and runs successfully, but the IDE shows a ton of undersquiggles in source files, being unable to resolve symbols and include files that the toolchain itself had no problem resolving, as evidenced by the binary being successfully produced. STEPS TO REPRODUCE 1. Project -> New from template... -> Qt -> Grahical (QMake-based) -> QtQuick 2 program 2. Build the project and run the executable to verify that it builds successfully 3. Open src/main.cpp in the IDE OBSERVED RESULT See attachment. EXPECTED RESULT The IDE should be able to figure out every symbol and include file that the toolchain itself was able to figure out.
