erreur de compilation

citizen94

Bonsoir, j'essaye de compiler un programme. Mais je reçois une erreur venant d'une classe de Qt: QString; je ne comprends pas pourquoi. Voici l'erreur:

C:\Qt\5.6\mingw49_32\include\QtCore\qstring.h:303: erreur : expected unqualified-id before 'const'
QString &vsprintf(const char *format, va_list ap) Q_ATTRIBUTE_FORMAT_PRINTF(2, 0);

Hi @citizen94

Do you have the same building error , when you build another program, or just with this program?

SGaist

Bonsoir et bienvenue sur devnet,

Ceci est un forum anglophone exception faite de la partie internationale. Je vous recommande donc de reformuler la question en Anglais.

That said, can you show the code that triggers this error ?

citizen94

ok right.
QString &operator=(QChar c);
QString &operator=(const QString &) Q_DECL_NOTHROW;
QString &operator=(QLatin1String latin1);
#ifdef Q_COMPILER_RVALUE_REFS
inline QString(QString && other) Q_DECL_NOTHROW : d(other.d) { other.d = Data::sharedNull(); }

with only tthe same program

but this error come out to the one function of Qt
So, I don't kwow what i must do. there is my mainly code:

the error don't come out of this mainly code but the one class of Qt; it is Qt creator

You have to many backslashes, remove the ones that are on leaf lines.

Then as @mostefa suggested, try to build a default application and if that succeed, try again using QString somewhere in it.

If these two succeed, then there's something fishy with your code.
