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 developer's located here:

Instructions on importing keys from a keyserver and how to automate the retrieval process can be found in the Arch Linux wiki here:
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>

I don't know how to verify the package: when I run "gpg --recv-keys 8F0871F202119294", I have a weird error:

gpg: Note: signatures using the SHA1 algorithm are rejected gpg: key 0x8F0871F202119294: 2 signatures not checked due to missing keys gpg: key 0x8F0871F202119294: 5 bad signatures gpg: key 0x8F0871F202119294: no valid user IDs gpg: this may be caused by a missing self-signature gpg: Total number processed: 1 gpg: w/o user IDs: 1

Is there a problem with this key?

EDIT: I got rid of my gpg.conf file during the GPG key import, and it worked. I think my gpg.conf is a bit too paranoid about the ciphers.

I got this error when building the package: (60) SSL certificate problem: certificate is not yet valid when downloading, but it seems like an upstream issue.

I can't seem to find the required PGP key in any keyserver (already ran "gpg --recv-keys 8F0871F202119294", gives an error, if I search for the key on keyservers there is no result...)

Edit: ran the same command today and it worked fine. Have no idea why the server was returning an error.

Add llvm-svn and clang-svn as dependencies, because the package is not compiling without them. (at least on my pc)

gpg --recv keys 8F0871F202119294

remember to use gpg --recv-keys in your user.

1- Download package snapshot right above box.
2- extract it and cd to folder.
3- makepkg -si

The upstream URL seems to be going down on a semi-regular basis lately, getting cannot resolve host errors when trying to install.

Okay, I fixed my issue by changing line 51 from

"CC=clang CXX=clang++ cmake \"


"CC=gcc CXX=g++ cmake \"

I keep failing with:

clang-5.0: error: unknown argument: '-mprefer-avx128'

clang-5.0: error: unknown argument: '-mvzeroupper'

My google-fu must be bad today because I can't find anything on this.
