Qt 5 Upgrade
This page is obsolete but has been retained for historical purposes.
Dependences
QT 5 requires libicu (a unicode lib) for WebKit Support. libicu doesn't appear to exist on many of our HPC systems.
Building libiuc
Windows MinGW build instructions
Linux build instructions:
Qt won't link successful against a static version of libicu b/c it does not explicitly link all the dependant libs.
wget http://download.icu-project.org/files/icu4c/49.1.2/icu4c-49_1_2-src.tgz tar -xzf icu4c-49_1_2-src.tgz cd icu/source ./configure --prefix=/install/path/icu/49.1.2/ make -j 8 make install
Building Qt
To point Qt's build system to your non-system libicu, use the -I and -L configure flags:
cd qt-everywhere-opensource-src-5.0.0 ./configure -opensource -confirm-license \ -I/install/path/apps/icu/49.1.2/include/ \ -L/install/path/apps/icu/49.1.2/lib/ \ -R/install/path/apps/icu/49.1.2/lib/ \ -qt-xcb \ --prefix=/install/path/apps/Trolltech/Qt-5.0.0/
