ArchLinux
---------
Installation on ArchLinux may encounter a few hiccups as Arch defaults to
python 3, but synapse currently assumes python 2.7 by default.
pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 )::
$ sudo pip2.7 install --upgrade pip
You also may need to explicitly specify python 2.7 again during the install
request::
$ pip2.7 install --process-dependency-links \
https://github.com/matrix-org/synapse/tarball/master
If you encounter an error with lib bcrypt causing an Wrong ELF Class:
ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
compile it under the right architecture. (This should not be needed if
installing under virtualenv)::
$ sudo pip2.7 uninstall py-bcrypt
$ sudo pip2.7 install py-bcrypt
During setup of homeserver you need to call python2.7 directly again::
$ python2.7 -m synapse.app.homeserver \
--server-name machine.my.domain.name \
--config-path homeserver.yaml \
--generate-config
...substituting your host and domain name as appropriate.

If running `$ synctl start` fails wit 'returned non-zero exit status 1', you will need to explicitly call Python2.7 - either running as::
$ python2.7 -m synapse.app.homeserver --daemonize -c homeserver.yaml --pid-file homeserver.pid
