 |
|
Here is the output from emerge world. It appears to be a problem emerging qtdeclarative for Qt6.
Any hints on obtaining a clean emerge world will be gratefully received. |

Usually this error is related to a hardware issue.

I used smartctl to test my NVMEs (no hard disk), memtest86+ to test my memory, and s-tui to test my CPU and the hardware passes these tests.
How would I go about checking for software problems? |

Please post the full command you're running. You should always do that. Include --verbose so we can see what's scheduled for merge. Also post your emerge --info although I already suspect you're running unstable.

| Code: | | emerge -uDN --verbose-conflicts --keep-going --with-bdeps=y @world 2>&1 | tee /tmp/emerge-world |
Here is what's scheduled to emerge.
This dies on emerging =dev-qt/qtdeclarative-6.7.2::gentoo
Here is emerge --info =dev-qt/qtdeclarative-6.7.2::gentoo.
Here is emerge -pqv =dev-qt/qtdeclarative-6.7.2::gentoo
Here is the build log.

Elsewhere there have been comments that if it fails in the same way every time, it is probably a software issue. So one method would be to try building it multiple times and see if if fails in a consistent manner.

I'm not sure how to provide this exactly nor where to find it. E.g. what is "ICE"? |

Ah, sorry, ICE = internal compiler error.
I need the, say, 20 lines after 'internal compiler error: Segmentation fault'. |

If segmentation faults occur in the compiling of, say, the C++ code of qtdeclarative does that indicate a problem with the compiler or the code of qtdeclarative? I'm uncertain of the meaning of "internal compiler error." |

It is the compiler. Have you enabled lto or some other optimization?

| A program with no bugs, running on hardware that works as documented, will never crash, no matter how ill-formed its inputs may be. C++ compilers are tested extensively, and while they doubtless have bugs (as any large program does), it should be exceedingly rare that a released C++ compiler can be crashed by bad inputs, especially when those inputs are themselves released source that many people have built successfully. Therefore, when dealing with released source code as input, it is generally very safe to assume that a compiler crash indicates either that the hardware did not behave as documented or that the compiler was itself mis-compiled, such that the program you are running is not what the released source code was intended to create. As logrusx's question suggests, Link Time Optimization is a somewhat common way to get a malfunctioning binary from a given source code release, whether due to bugs in the LTO code or bugs in the compiler that are only exposed under the heightened optimization of LTO. |

LTO/PGO is not related to any CPU. Those are done by the compiler/linker.
p.s. I already checked your make.conf for an lto/pgo use flag, although it should not be there.

It appears that my problem occurs with compiling QT6 packages which, I assume, are pulled in by KDE6. I'm "happy" to revert to KDE5 just to get a working graphic system again.
Is there documentation on how to revert to an earlier version of KDE? |

I would speculate the problem is in your compiler, because you're running testing and it's something like p202406something, which is very recent, but I can't prove it. I'm also not sure if it's OK to downgrade it.

Would it be "safe" (or useful) to emerge the first two and then try emerging world? I assume they would go in the same slot as the third, my current compiler. |

I don't know. What I can tell you for sure is you should not downgrade glibc. If I were you I would quit running testing. If you're up for that idea, there are a few threads on how to downgrade to stable without breaking your system. You can also open a new one as this usually is specific for the specific user.
The general rule for downgrading is to remove ~amd64 from your make.conf and see what are the packages that are scheduled for downgrade. Put some versioned entries in package.accpet_keywords for the packages that should not be downgraded and wait for those to get stable versions. They should be in the form of <=caregory/package/version so that you're sure portage won't try to build anything lower then the currently installed version. One such package is glibc but I think there were others too.
