Please read the AUR wiki page before reporting issues.

In addition, if you are experiencing a build issue then ensure you have tried building without using an AUR helper (e.g. makepkg) and with a clean chroot (e.g. makechrootpkg).

I'm keeping an eye on FS#70701 to see what the approach will be. Switching CFLAGS seems like a workaround.

That's a recent addition to makepkg.conf's CFLAGS (https://github.com/archlinux/svntogit-packages/commit/a790c389cb0fd2ddd35e1f581ee337f6891801fc#diff-8da5d04d27b7ace195751c5e1e5e52c0bbd59e1ec3fd89d656496cc1d272d4b0).

The file's lines that error (libcpp/expr.c) haven't changed between GCC8 and GCC11 so this may be an upstream bug...

Not sure why but I have to remove the compilation flag -Werror=format-security from CFLAGS in order to build these packages. I don't know where the -Werror=format-security comes from. I don't see that flag in makepkg.conf. Anyway, I added the following lines to the build section to make it work:

CFLAGS=${CFLAGS/-Werror=format-security/}
CXXFLAGS=${CXXFLAGS/-Werror=format-security/}

I'm using clean build.

To avoid using the aur as per jonathon's comment, I attempted to build the package using extra-x86_64-build after cloning the repo. This would however fail installing and when checking the build would say

==> Running checkpkg error: target not found: gcc8 error: target not found: gcc8-libs error: target not found: gcc8-fortran ==> WARNING: Skipped checkpkg due to missing repo packages

to which I just tried using the aur helper yay and was installed successfully.

Some of the testcases failed, and counted as "unexpected failures". Like

                === g++ Summary ===

# of expected passes            126511
# of unexpected failures        9
# of expected failures          506
# of unsupported tests          5202

But the packaging procedure still finished. Is that normal?

It ends with this compilation error:

(I've compiled with the PKGBUILD without any aur-helper)

In addition, if you are experiencing a build issue then ensure you have tried building without using an AUR helper (e.g. makepkg) and with a clean chroot (e.g. makechrootpkg).

Thanks, Jonathon. Building in a clean chroot was the answer.

Add this GPG key to your user key-chain by running this in a terminal:
gpg --recv-keys A328C3A2C3C45C06
If this doesn't work, then try another keyserver, for example:
gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys A328C3A2C3C45C06

EDIT: Oh, and be warned if you run this single-threaded: this will take a long time. Over 2 hours for me already. Don't forget to run this with make -j X where X is equal to the number of threads you want to use, if you haven't changed the default number of threads make uses.

Hi! Thanks for uploading the package since it's been removed from official repositories.

However, it's falling due to GPG keys error: FAILED (unknown public key A328C3A2C3C45C06)
