See the github wiki for
documentation. You can also check out the example code under the
example directory and run erld -h for an explanation of
parameters.
To build and install from a clean checkout:
./bootstrap.sh
./configure
make
sudo make install
erld doesn't require much to build. In addition to Erlang, you will need libproc and its development files (headers etc) and that should be all (aside from standard stuff like a compiler and autotools which pretty much any developer will already have installed).
There are no specific version restrictions on Erlang that we're aware of - we've been running this code since R13 and are still using it without signficant modification on R15. If you do encounter a problem with a particular version, please let us know.
