Should I Worry About Emerge Failures?

Jojobinha_2009

I know this comes with the territory, some packages will eventually break.
For example today, 2 Plasma 5.21.4 packages temporarily failed to compile, that was solved afterwards by re-emerging them.

Do these build failures represent any risk to my Gentoo install's integrity?

This is all very new to me.

Merges should be deterministic. If it fails and passes the next time around, there is a problem that needs to be fixed.

Usually nondeterministic behavior points to bad hardware somewhere in the chain, like distcc.

Other possibility is if a dependency chain was not completely specified in the ebuild - this is actually a bug that should be fixed. Posting details about the failure could help people find what the problem is.

Usually errors:
- Segmentation fault, bus fault, error 11, etc. - Usually hardware issue
- Link errors. usually bad dependency chain issues - need to fix in ebuild
- File not found errors. Usually dependency or distcc issues.
- Bad file format errors. Usually distcc issues.

If you're emerging one package over and over again (i.e. without dependencies or other packages in between) and sometimes it fails - this is usually a hardware issue. If you're using --keep-going and restarting the emerge usually finishes the next go-around after it changes the order of packages merged, this is usually a bug.

Ok. Thank you.

When I ran the emerge again, both ebuilds compiled just fine.

Jojobinha_2009,

That sounds like a missing dependency bug, so you eventually compiled everything you need but in the wrong order.
It may well happen again.

Keep the build log if it does as the build long will be required to work out what the problem is.
