Hi people, this is your regular reminder to SHUT UP about validpgpkeys checks and complaints about the fact that test suites exist.

This package is doing the correct thing, and there has been a great deal of pointless moaning and whining about it, but there is also multiple pinned comments explaining why every one of those complaints is not only null and void, but retroactively ridiculous.

The banhammer is ready and waiting in case you still want to ignore all this on top of the Trusted User warning.

Holy shit guys. What's unclear about "AUR helpers are not supported"? Stop this incessant spam and learn how to use makepkg.

https://wiki.archlinux.org/index.php/Makepkg https://wiki.archlinux.org/index.php/Arch_User_Repository

Any comments on AUR helper issues will be deleted from now on. Repeat offenders will have their accounts suspended.

WoefulDerelict commented on 2018-07-21 11:45

If you experience issues when using an AUR helper please try again using makepkg. AUR helpers are not supported here. The AUR article in the ArchWiki documents the prerequisites and supported process. https://wiki.archlinux.org/index.php/Arch_User_Repository

The test suite contains tests for multiple locales including: en_US.UTF-8, fr_FR.UTF-8, ru_RU.UTF-8, zh_CN.UTF-8, fr_CA.ISO8859-1 and cs_CZ.ISO8859-2. If a locale isn't present on the system the related tests will be marked as unsupported and skipped.

If you encounter issues when building with makepkg please attempt to build this in a clean chroot using using the appropriate devtools script. The Arch Linux DeveloperWiki has an article focused around building packages in a clean chroot which contains information on the devtools scripts and explains the process of building in a clean chroot: https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot

There is an active community of users on IRC along with a vibrant Discord server and Forums should you require assistance.

Picking a fight with one of the Trusted Users is a terrible idea.

This PKGBUILD verifies the authenticity of the source via PGP signatures which are not part of the Arch Linux keyring. In order to complete the process it is necessary to import the key(s) from the ‘validpgpkeys’ array into the user’s keyring before calling makepkg. There is a helpful article explaining this process by one of Arch Linux's developers located here: http://allanmcrae.com/2015/01/two-pgp-keyrings-for-package-management-in-arch-linux/

Instructions on importing keys from a keyserver and how to automate the retrieval process can be found in the Arch Linux wiki here: https://wiki.archlinux.org/index.php/GnuPG#Use_a_keyserver This article also contains helpful information describing the installation of GnuPG, its configuration and usage.

Execute the following to import keys using gpg:

gpg --recv-keys <KEYID - See 'validpgpkeys' array in PKGBUILD>

The PGP signature check can be skipped by passing --skippgpcheck to makepkg.

The libc++ test suite can be skipped by passing --nocheck to makepkg.

Consult the makepkg manual page for a full list of options. [https://www.archlinux.org/pacman/makepkg.8.html]

@fightcookie Check the download page: https://releases.llvm.org/download.html

"Signed with PGP key 86419D8A."

Where can I find the fingerprint of the (new) pgp key on the internet to verify it against this pkgbuild? I can't seem to find it anywhere on the upstream url.

Read the pinned comment.

There is a problem with the tests I ran into. During one of the compilations during testing, the linker failed. The reason for this failure was, that I have enabled link time optimization (LTO) in /etc/makepkg.conf. I was able to resolve this by completely removing LTO from the build in PKGBUILD. Here is the diff:

Build it with --nocheck option for makepkg:

makepkg -sri --nocheck

Just stating «not working» does not help at all. I'm getting this error message:

ERROR: One or more PGP signatures could not be verified!

With french locale setup I got an error :

I just changed /etc/locale.gen to en_US.UTF-8 UTF-8 then compile and all went fine.

maxlefou: It would take a significant amount of time to run through the test suite with just two threads. How long is it hanging at the test progress bar without changing? You can pass --nocheck to makepkg to skip the tests.

Morganamilo commented on 2018-03-26 18:04

@maxlefou how long is forever?

And you can just pass --nocheck to makepkg.
