Where to get UIC?

Liss

I am attempting to put together an interface that is defined at compile time. I designed this interface in QT Designer. I see that I can use the User Interface Compiler to turn my .ui file into c++. What I cannot find is where to grab or how to install the UIC? I'm on Fedora Workstation 40. I've googled around; I've searched my distro's repositories; where do I find this piece of software?

Hi and welcome :)

How did you install Qt? Are you using QtCreator as IDE?

Usually the user interface compiler comes with your Qt installation.

Can't speak for Fedora but usually it's located in your Qt dir.
Somewhere around path/to/Qt/<Qt_version>/<your_compiler>/bin

Thank you so much for getting back to me! I installed QT using the QT Maintenance Tool (I'm in the process of refactoring an old code base away from wxWidgets, so I'm very new to Qt). I've been all around my /opt/Qt/ directory, but can find no trace of anything called uic. I am not using QtCreator, just QtDesigner and then doing the actual coding in CLion.

uic is somewhere in /opt/Qt/ - otherwise you did not install Qt correctly.

Like @Christian-Ehrlicher already said, there must be.
What do you have inside your /opt/Qt dir?
Have you searched manually or recursively with your File Manager on Fedora?

Check, if a path like /opt/Qt/6.7.0/gcc/bin exists, where you replace 6.7.0 with the actual Qt version you have in use and gcc with your compiler toolchain.
uic is expected to be located there if you installed it as "Kit" with your Qt installation.

Liss

I was able to locate /opt/Qt/6.7.2/gcc_64/bin/ but there is no uic in that directory. Does this mean I installed incorrectly?

Christian Ehrlicher

There must be moc, uic, designer and other tools in this directory. If there is nothing wrt this - yes, you did something wrong.

What parts/modules did you install exactly when using the Online Installer?
Did you do a standard Qt 6.7.2 installation or did you choose custom installation and then unchecked everything except the Qt Libs?
(I don't know if it is even possible to install Qt without moc, uic and the other tools... haven't tried it myself)

Liss

Okay, so I wiped my Qt install, and re-installed everything through the Online Installer. I selected the desktop development option, didn't click anything else to customize, and installed. The UIC still isn't there. I'm at a loss.

That's impossible. There is no way that a standard installation doesn't include tools like uic.

Even if you don't plan to use it: Start QtCreator, create a new project and try to compile any *.ui form to a C++ header.
If it works there must be a uic somewhere :)

Liss

I opened up QtCreator and imported the project. Nowhere could I find an option to compile the .ui file. Maybe I just don't know where to look?

Liss

I solved it! After playing around with some regular expressions, I was able to locate it at /opt/Qt/6.7.2/gcc_64/libexec/uic

What it was doing in there I do not know. But thank you all for the help.

So you didn't searched the directory with you File Explorer?
A recursive directory search starting in /opt/Qt/6.7.2/gcc_64 would have revealed the uic tool way earlier :))

@Liss
For next time I suggest you do a

find / -name uic -print

rather than trying to guess where something might be when you are trying to locate some file under Linux.
