Description
Edit: this happens when two include files include each other and include guards are used. It does not happen with #pragma once. Please see comment further down for minimal example
In one very specific case, Qt Creator incorrectly highlights and shows an error when using nested conditional directives.
Error shown:
#ifndef COMMON_H // <-- unterminated conditional directive #define COMMON_H #include <cstdint> #ifdef ISSERVER #include <QSqlQuery> #include <log.h> #endif // ... namespace Common { // ... #ifdef ISSERVER // ... #endif // ISSERVER } #endif // COMMON_H
No error:
#ifndef COMMON_H #define COMMON_H #include <cstdint> #ifdef ISSERVER #include <QSqlQuery> //#include <log.h> // <-- commented #endif // ... namespace Common { // ... #ifdef ISSERVER // ... #endif // ISSERVER } #endif // COMMON_H
#pragma once // <-- added #ifndef COMMON_H #define COMMON_H #include <cstdint> #ifdef ISSERVER #include <QSqlQuery> #include <log.h> #endif // ... namespace Common { // ... #ifdef ISSERVER // ... #endif // ISSERVER } #endif // COMMON_HÂ
