c++ - Vinculación contra libQt5Core
ubuntu compilation (5)
En mi caso funcionó después de hacer 3 enlaces simbólicos. La biblioteca estaba instalada pero tenía una versión más nueva (55) que la esperada (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
Instalé Qt5.4 con el instalador en línea (trabajando en ubuntu 14). Estoy tratando de compilar mi fuente y enlace de c ++ contra libQt5Core pero ld arroja un error:

sudo apt-get install libicu-dev
Me encontré con el mismo problema. Pero encuentro mi salida solo por este código.
export LD_LIBRARY_PATH=/usr/local/Qt/5.5/gcc_64/lib:$LD_LIBRARY_PATH
Recibo este error cuando intentaba construir Iris en Ubuntu. Lo resolví eliminando CONFIG + = static del archivo .pro
Recibo estos errores cuando intentaba compilar mi proyecto en Debian 8 (con libicu52 del repositorio oficial) de QtCreator. Lo resolví cambiando ''Ambiente'' para mi Qt Kit (5.8.0) a: LD_LIBRARY_PATH = / opt / Qt / 5.8 / gcc_64 / lib: $ {LD_LIBRARY_PATH}.
