How to fix missed libicui18n.so.74 when adding qmake to Qt Creator?
-
Hello.
Yesterday, I built Qt 6.11.2 from source on my Ubuntu 24.04 laptop for I wanted to learn Qt Quick and QML (as a C++ dev, I already had some experience with Qt Widgets, but mostly only with their side of the framework). The building went well, and soon I got it done. Yet, I couldn't add this build to Qt Creator 20.0.1, when I was manually adding qmake or qmake6 to Qt Versions within Kits, I got an error:
The qmake executable /home/tea/Apps/qt-6.11.2/bin/qmake could not be added: "/home/tea/Apps/qt-6.11.2/bin/qmake" produced no output: /home/tea/Apps/qt-6.11.2/bin/qmake: error while loading shared libraries: libicui18n.so.74: cannot open shared object file: No such file or directory.
Today I've confirmed with apt that I actually do have ICU installed in the system:
libicu74 is already the newest version (74.2-1ubuntu3.1). libicu74 set to manually installed.The exact library
libicui18n.so.74.2lies in/usr/lib/x86_64-linux-gnu/.Right now I don't know what to do to fix that. Maybe, that's me doing anything wrong, or that's another issue. So, any help would be highly appreciated.

@Irimitlad said in How to fix missed libicui18n.so.74 when adding qmake to Qt Creator?:
The exact library libicui18n.so.74.2 lies in /usr/lib/x86_64-linux-gnu/.
and is there libicui18n.so.74 symbolic link in /usr/lib/x86_64-linux-gnu/ pointing to it?
Is there a reason to build Qt by yourself? -

Hi and welcome to devnet,
Can you also share the output of
ldd /home/tea/Apps/qt-6.11.2/bin/qmake? -
First, thank you everyone for helping.

Why is it looking in /usr/local/lib?
Did you install this lib by yourself?Regarding installer being stuck: take a look at https://wiki.qt.io/Online_Installer_4.x#Selecting_a_mirror_for_opensource
