Arch Linux User Repository

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.

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

Hi, why has the source moved from gtp.gnu.org to invisible-island.net? The sources are still available on gnu.

Moreover, the ftp.gnu.org over https is encouraged, and this was already working

The "server timing out for me" mostly points to an issue with your own network. Does anyone of you have a direct involvement with invisible-island.net? Or has a way and TIME to verify the sources from there actually match?

In the sense of, yes invisible-island.net is fine as it is directly maintained by the developer of ncurses, who also signs the packages. Nevertheless, isn't it riskier to use a non gnu website when this is available? Just consider the risk of any website being compromised, and then consider which website will find out first between gnu and a smaller one

@matthewq337: we can change it, but I had no issue so far with ftp.gnu.org.

The gnu ftp is timing out at least for me atm. Maybe you could switch to the no less official https://invisible-island.net/archives/ncurses/ ?

Fixed, sorry for long wait

@FuzzyMidnight, can you please elaborate. adding this to the 2 ./configure commands in the PKGBUILD did not resolve the problem. and attempting the method you link to doesnt work because the Makefile.in 's dont seem to have a CFLAGS i can alter (in the main Makefile)

--REDACTING, as i edited the PKGBUILD, and ran via the linked steps and it built.... thanks

for everyone else, this is what seemed to work in my instance

git clone ... makepkg --nobuild <EDIT PKGBUILD the 2 ./configure... lines need to be edited> makepkg -i --noextract

including -std=gnu17 allows it to build with gcc15

such as including CFLAGS="$CFLAGS -std=gnu17" before ./configure

thanks @ModelHX for pointing it out on another package https://aur.archlinux.org/packages/units#comment-1022118

@Juve-lvh thank you for your comment, building with gcc-14 worked for me as well.

My version of gcc is 15.1.1. I try to install it with gcc 14.2.1 and it works just right

Getting multiple redefinition errors while building, first error is:

I'm using gcc version 15.1.1 20250425.
