Bug 476578 – [qt overlay] dev-util/cmake - Qt5 found, but uses Qt4's uic version (/usr/bin/uic)

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Stefan Böhmann 2013-07-11 20:45:28 UTC]

With Qt5 (5.1.0 from qt overlay) a cmake based project can find the right Qt version (if Qt5 and Qt4 is installed) and can compile and link basic code. 

But the build fails, when I use ui files (Qt Designer files) in my Qt5 project. Looks like cmake then uses the wrong uic binary (/usr/bin/uic instead of /usr/lib64/qt5/bin/uic). Therefor it generates code with an QtCore/QAction include instead of the right QtWidgets/QAction include and the compile fails. 

Maybe similar applies for other Qt executables (rcc, moc, ...).

Reproducible: Always

In the second file you attached there's

    set(imported_location "${_qt5Widgets_install_prefix}/lib64/qt5/bin/uic")

so the path looks good to me.

Can you attach a testcase that reproduces the failure please?

Sorry guys. It turned out that there was an error in my makefile. I had forgotten to call find_package(Qt5Widgets), but the error message has put me on the wrong track.

Thank you for your efforts!
