In QT,how to distinguish debug and release in someway like preprocessor

debugging, preprocessor, qt, release

Solution

The correct Qt macros for that is `QT_DEBUG`. So you code will be:

QString Paths::sqlScriptPath()
{
#ifdef QT_DEBUG
    return "D:\edocclient\edocclient-build-Desktop_Qt_4_8_4_QT4_8_4-Debug\sql";
#else
    return "D:\edocclient\edocclient-build-Desktop_Qt_4_8_4_QT4_8_4-Release\sql";
#endif
}

Problem

I know we can use #if DEBUG #else #endif in c#,so i think Qt has the same way to do that, like this： ``` QString Paths::sqlScriptPath() { #if DEBUG return "D:\edocclient\edocclient-build-Desktop_Qt_4_8_4_QT4_8_4-Debug\sql"; #else return "D:\edocclient\edocclient-build-Desktop_Qt_4_8_4_QT4_8_4-Release\sql"; } ``` but it didn't work.
