Project:Tinderbox/Common Issues Helper
This page is still a work in progress
This page is intended to provide useful resources for understanding and fixing common Quality Assurance notices, build failures and so on. At some point it will probably moved to the Gentoo Devmanual.
Rules
The following numbers means nothing, but they can make the life easy when they will be linked in the bug reports. For this reason, please do not edit or existing numbers, instead, please add a new one for new warnings/failures.
Add new code
If your 'QA Notice' or 'compile failure' has not been reported here, feel free to add it, and at the end, please notify members of the project so they can link the new documentation to the related warnings/failures.
Approval/review
How approval/review works
It's a matter of fact that everyone can edit this page, so the important thing is that informations need to be reviewed and approved from a member of the team that implemented that check. If you are editing something that has already been approved, you need to remove the nickname of the person that approved the information and ask again for an approval. In that way we are sure from the wiki history that it was really approved from the right person.
Syntax
For a developer called John, that is approving as part of toolchain project, the correct (wiki) syntax should be:
✅ [[User:John|john]] ([[Project:Toolchain|Toolchain]])
For a developer called John, that is approving as part of multiple projects, like toolchain/qa the correct (wiki) syntax should be:
✅ [[User:John|john]] ([[Project:Toolchain|toolchain]]/[[Project:Quality_Assurance|qa]])

* This package will overwrite one or more files that may belong to other * packages (see list below). You can use a command such as `portageq * owners / <filename>` to identify the installed package that owns a * file.

A bug report is only useful if it identifies at * least two or more packages that are known to install the same file(s). * If a collision occurs and you can not explain where the file came from * then you should simply ignore the collision since there is not enough * information to determine if a real problem exists. Please do NOT file * a bug report at https://bugs.gentoo.org/ unless you report exactly * which two packages install the same file(s). See * https://wiki.g.o/wiki/Knowledge_Base:Blockers for tips on how * to solve the problem.

Description
The package installs libraries and/or binaries that are linked to libraries not declared in RDEPEND. You didn't notice issue because the missing libraries are already pulled in by something else. You should check:
- If this is an automagic case (see the link above)
- If the RDEPEND is unconditionally or it is needed only in case of an enabled USE
- If, apart declare the missing packages as RDEPEND, you need to declare sub-slot and/or slot-operators
How to reproduce
qlist -e $package:$slot | xargs scanelf -BF '%n'
How to fix
