Need help building from source: "No Qt6 qtpaths executable found." error

Zenurik

For context, I'm trying to build this software: https://github.com/matinlotfali/KDE-Rounded-Corners
When running cmake .., I'm getting this error:

CMake Error at /usr/share/ECM/modules/ECMQueryQt.cmake:82 (message):
  No Qt6 qtpaths executable found.  Can't check QT_INSTALL_PREFIX as required
Call Stack (most recent call first):
  /usr/share/ECM/kde-modules/KDEInstallDirs6.cmake:197 (ecm_query_qt)
  /usr/share/ECM/kde-modules/KDEInstallDirs.cmake:15 (include)
  CMakeLists.txt:15 (include)

I don't seem to have a qtpaths file for Qt6 specifically, I can only find a generic one inside /usr/bin, and setting that as the value for the QT_INSTALL_PREFIX variable doesn't work.

Both qt5-base and qt6-base were already pre-installed in my system and I did install the system.devel and extra-cmake-modules packages

qt6-base package contains /usr/lib64/qt6/bin/qtpaths and /usr/lib64/qt6/bin/qtpaths6. It should have worked. No idea why it doesn't work for you.

alfisya I don't seem to have those files 🤔

Try install qt6-base-devel

Yeah, what @pomon said, those files are part of the qt6-base-devel package, not qt6-base

eopkg sf /usr/lib64/qt6/bin/qtpaths
Searching for /usr/lib64/qt6/bin/qtpaths
Package qt6-base-devel has file /usr/lib64/qt6/bin/qtpaths

eopkg sf /usr/lib64/qt6/bin/qtpaths6
Searching for /usr/lib64/qt6/bin/qtpaths6
Package qt6-base-devel has file /usr/lib64/qt6/bin/qtpaths6

That was it. I eventually got there and was able to build it after some other dependency conflicts

Staudey eopkg sf /usr/lib64/qt6/bin/qtpaths

That command is very useful 😲

Zenurik That command is very useful 😲

Unfortunately only works for installed packages. The Serpent tools will be much better in this regard.

For future reference, here's all the dependencies I needed to build KDE Rounded Corners on Solus:

- system.devel
- extra-cmake-modules
- qt6-base-devel
- libepoxy-devel*
- kf6-kcmutils-devel
- kwin-devel*

The ones with an asterisk I got from their dependency list on other distros and might not be needed

Thanks!

Zenurik that will help someone down the road. good job.
