Hi, and thanks for the opportunity to try you next thing. Trying to build it on Arch Linux, no luck. I see it's not officially supported, just letting you know.

Interesting. I see this fails in an AX_* m4 macro. Have you installed the autoconf-archive package?

[dsommers]

In regards to supporting Arch Linux. It is currently not listed as officially distro as we don't have any one internally running that. But if we have someone willing to be an Arch Linux package maintainer, we can surely add that as a supported distro.

[dsommers]

Closing this now. It is reasonable to believe this issue was due to lacking the autoconf-archive package.

[Thor-x86]

Error still persist on Ubuntu 20.04, autoconf-archive is installed, also with required dependencies based on ./configure

EDIT: The real solution is when autoconf-archive installed, re-clone the git and run ./bootstrap.sh again

[dsommers]

Rerunning bootstrap.sh after installing autoconf-archive package should normally be more than enough.

If this issue appears when building from the release source tarballs, just running autoreconf -i should also be enough.
