Obviously I would like to now know what version of dev-qt/qtcore is installed and perhaps any other information about your system that relates to Qt.

Looks like it's looking for Qt5 when that ought to be disabled:

net-analyzer/wireshark-3.2.5::gentoo was built with the following:

But your build log has USE=qt5:

What is going on?

[Comment 12 Sam James 2021-04-18 03:19:05 UTC]

It’s unclear what the issue is/what needs to happen here. Still a problem?

[Comment 13 Wim van Ravesteijn 2021-04-20 07:42:23 UTC]

Unfortunately, problem is still there, but problem is not in wireshark, but in qt. Also other packages requiring qt have same problem. Unfortunately it is not clear to me what is causing the problem. I did already a full rebuild of the system, but this has not solved the problem.
Maybe someone has a hint where to look for what? When I get this message, which files have been looked up where?

[Comment 14 Wim van Ravesteijn 2021-08-09 22:45:43 UTC]

I have a new laptop, and it worked fine the first weeks compiling packages requiring qt5. But suddenly it stopped working again, while my desktop all the time did not face any trouble. I've been comparing configurations and strace output, and I noticed the following:

# strace -f emerge -av1 kde-apps/konsole kde-apps/gwenview 2>/tmp/emerge.strace

This failed at my laptop.

# grep Qt5CoreConfig emerge.strace  | cut -f2 -d'"' | uniq -c
      3 /usr/lib/portage/python3.9/ebuild-helpers/xattr/Qt5CoreConfig.cmake
      3 /usr/lib/portage/python3.9/ebuild-helpers/Qt5CoreConfig.cmake
      3 /usr/local/Qt5CoreConfig.cmake
      3 /usr/Qt5CoreConfig.cmake
      3 /Qt5CoreConfig.cmake
      3 /opt/Qt5CoreConfig.cmake
      3 /usr/lib/llvm/12/Qt5CoreConfig.cmake

Apparently, in these folders there is no Qt5CoreConfig.cmake. On my desktop, installation succeeded, there strace has following:

# grep Qt5CoreConfig emerge.strace  | cut -f2 -d'"' | uniq -c
      3 /usr/lib/portage/python3.9/ebuild-helpers/xattr/Qt5CoreConfig.cmake
      3 /usr/lib/portage/python3.9/ebuild-helpers/Qt5CoreConfig.cmake
      3 /usr/local/Qt5CoreConfig.cmake
      3 /usr/Qt5CoreConfig.cmake
      3 /usr/lib64/cmake/Qt5Core/Qt5CoreConfig.cmake
      3 /usr/lib64/cmake/Qt5Core/Qt5CoreConfig-version.cmake
[...]

I cannot figure out what causes this difference, but I did find a fix. Created a new file /etc/profile.d/cmake.sh with content:

export CMAKE_FRAMEWORK_PATH="/usr/lib64/cmake/:${CMAKE_FRAMEWORK_PATH}"

This goes pretty straight to the right path:

# grep Qt5CoreConfig emerge.strace  | cut -f2 -d'"' | uniq -c
      3 /usr/lib64/cmake/Qt5CoreConfig.cmake
      3 /usr/lib64/cmake/Qt5Core/Qt5CoreConfig.cmake
      3 /usr/lib64/cmake/Qt5Core/Qt5CoreConfig-version.cmake
[...]

Maybe this helps figuring out what broke my config, or a hint where to look to properly fix it. And if not, I keep my export.

Sorry, I missed this comment!

Could you upload a fresh build.log for e.g. konsole or gwenview to this bug, along with a build log for dev-qt/qtcore?

/opt seems weird...

/usr/local should *not* be there, surely, just like /opt?

Still a problem?

wireshark-3.6.2 builds fine for me with USE='qt5'.

[Comment 19 Wim van Ravesteijn 2022-03-29 10:09:52 UTC]

Unfortunately, problem is still there if I remove this:

export CMAKE_FRAMEWORK_PATH="/usr/lib64/cmake/:${CMAKE_FRAMEWORK_PATH}"

With this export (see comment 14), everything works fine.

[Comment 20 Andreas Sturmlechner 2022-07-16 16:45:51 UTC]

https://cmake.org/cmake/help/latest/variable/CMAKE_FRAMEWORK_PATH.html

According to cmake docs this is a macOS variable?
