Another tool that helps checking the security configuration of a system.
Stable worked out of the box here.
Latest keyworded requires sys-apps/grep[pcre] here which isn't defaulted to, just another untested published ebuild.
The later possibly provides better accuracy.

What did you see that led you to think that USE=pcre is needed here? Is there an open bug report about this? |

The point of this post is about how useful a package can be.
| Code: | | grep: Perl matching not supported in a --disable-perl-regexp build |
And no I won"t open a bug report for an untested keyworded ebuild, sorry.
The rest is a side effect of upstream organization.
Plz feel free 2 turn to the ones in charge, if any.
| Code: | | 2024-07-13T20:27:39 >>> app-admin/checksec: 1′39″ |
May be this will encourage you to do a less than 5 mn testing, and hopefully do the reporting.
Thks 4 your attention, interest & support.

You didn't mention a version, but the package has a stable version on the "common" platforms. | Code: | $ eshowkw checksec
Keywords for app-admin/checksec:
| | u |
| a a p s l r a | n |
| m r h p p i o i s l m m | e u s | r
| d a m p p c a x a o s 3 p 6 i | a s l | e
| 6 r 6 p p 6 r 8 6 n c 9 h 8 p | p e o | p
| 4 m 4 a c 4 c 6 4 g v 0 a k s | i d t | o
---------+-------------------------------+-------+-------
2.4.0-r1 | + + + o ~ + ~ + o o ~ o o o ~ | 7 o 0 | gentoo
2.5.0-r1 | ~ ~ ~ o ~ ~ ~ ~ o o ~ o o o ~ | 7 # | gentoo
2.6.0-r1 | ~ ~ ~ o ~ ~ ~ ~ o ~ ~ o o o ~ | 8 # | gentoo
2.7.0 | ~ ~ ~ o ~ ~ ~ ~ o ~ ~ o o o ~ | 8 # | gentoo
2.7.1 | ~ ~ ~ o ~ ~ ~ ~ o ~ ~ o o o ~ | 8 o | gentoo |
Filing bug reports on a ~ package version is one way they can become stable.

It looked like the point was to gripe that the RDEPEND for app-admin/checksec was not perfect out of the box. I'm not involved with this package, but I've had USE=pcre on my grep for years, so if I were the one testing this, I would have missed this in simple run testing. Only an inspection of every invocation of grep in the package would have flagged it. | CaptainBlood wrote: | | Code: | | grep: Perl matching not supported in a --disable-perl-regexp build |

Yes, that looks like grep's error message for using -P when PCRE support is missing. However, you did not show how checksec reached that point. Is it a failure to build? A failure to run? If the latter, with what options? | CaptainBlood wrote: | | And no I won"t open a bug report for an untested keyworded ebuild, sorry. |
Then no one will notice that this has a problem, and it will not get better. If you don't want to report bugs, you should be prepared for bugs to linger in packages that you use. | CaptainBlood wrote: | The rest is a side effect of upstream organization.

I don't understand this. I'm trying to get you to contribute to the community instead of just complaining that someone missed a dependency (which, per above, I would have missed if I were the tester and only checked that it ran correctly). | CaptainBlood wrote: | | Code: | | 2024-07-13T20:27:39 >>> app-admin/checksec: 1′39″ |

I have no use for this package. I don't know how you provoked the error. My grep won't fail with it, because I have USE=pcre. Therefore, no, it will not encourage me. You are already set up to file the report, you know how to make it fail, and you seem to care about whether this is right. Therefore, it seems to me like you are better positioned to make the report, and to answer any follow-up questions about it. |

Changelog isn't clear about this new requirement, starting with app-admin/checksec-2.7.0 though.
