Liaison avec libQt5Core

J'ai installé Qt5.4 avec le programme d'installation en ligne (fonctionnant sur Ubuntu 14). J'essaie de compiler ma source c ++ et mon lien avec libQt5Core mais ld envoie une erreur:

J'ai rencontré le même problème. mais je trouve mon chemin juste par ce code.

export  LD_LIBRARY_PATH=/usr/local/Qt/5.5/gcc_64/lib:$LD_LIBRARY_PATH

Je reçois de telles erreurs lorsque j'essayais de construire mon projet sous Debian 8 (avec libicu52 du dépôt officiel) de QtCreator. Je l'ai résolu en changeant 'Environnement' pour mon Kit Qt (5.8.0) en: LD_LIBRARY_PATH =/opt/Qt/5.8/gcc_64/lib: $ {LD_LIBRARY_PATH}.

Capture d'écran: modifications marquées par une ligne rouge

Dans mon cas, cela a fonctionné après avoir créé 3 liens symboliques. La bibliothèque a été installée mais j'avais une version plus récente (55) que celle attendue (54).

Sudo ln -s /usr/local/Qt/5.5/gcc_64/lib/libicui18n.so.54 /usr/lib/x86_64-linux-gnu/libicui18n.so.54
Sudo ln -s /usr/local/Qt/5.5/gcc_64/lib/libicuuc.so.54 /usr/lib/x86_64-linux-gnu/libicuuc.so.54
Sudo ln -s /usr/local/Qt/5.5/gcc_64/lib/libicudata.so.54 /usr/lib/x86_64-linux-gnu/libicudata.so.54

J'obtiens cette erreur lorsque j'essayais de construire Iris sous Ubuntu. Je l'ai résolu en supprimant CONFIG + = static du fichier .pro
