[SOLVED] unable to emerge KDE-related apps, ninja error

[leifdotwav]

hey all,
i'm trying to do a fresh install of gentoo using the kde plasma environment. however, i can't seem to emerge konsole or dolphin, as both of them fail to compile. during the build process, this one line stuck out to me the most:

if needed, i can post the entire output of the build, but i think this is what's wrong. thanks in advance.

hey all,

Code: Select all

ninja: error: manifest 'build.ninja' still dirty after 100 tries

This almost certainly means your clock is wrong. Try chrony or similar.

synced my time, and waited a few hours just to be safe (i also had to sleep), logged back into my setup, and the emerge worked??? thanks so much! it looks like you're a dev for gentoo, so could you explain why the time needs to be synced for certain emerges to work? thanks in advance.

Sure! The idea is that it needs to be sure that there aren't stale files left over by e.g. the upstream developer who made the tarball. Or maybe that the generated Makefiles (or ninja files) are out of sync with the list of things to build. The generated files must have a timestamp after the list of things to build, which ensures it is fully up to date.

If the generated files look like they were modified before the list of things to build (which we use to generate them), it implies that our generator is doing something wrong. That's what it means when it says "still dirty after 100 tries". It's trying to regenerate over and over but the timestamps still don't make sense to it.

I hope that kind of makes sense, I think I've got it the right way around

Generally, most build systems will have this requirement regarding time. Only the simplest ones, which run every step from beginning to end, every time, can ignore the clock. Anything that supports resuming (and most developers quickly find themselves wanting that) will inspect times to determine what steps to skip. As sam_ says, if a newly generated file is older than the file from which it was created, the build system will usually react badly. The careful ones abort with an error. The sloppy ones just keep going, and risk producing nonsensical results.
