If you use Debian or a related distribution: in older versions this file was included in the package erlang-nox, and in recent versions it is in erlang-tools. It means it couldn't find in your system the file make.beam, which is part of Erlang/OTP. If you get this error message while compiling exmpp: Git clone git:///exmpp/mainline.git exmpp_mainline You must have the latest version of the autotools, Erlang/OTP R12B-5 or later version and expat (tested with version 2.0.1). Make sure you have the following dependencies installed:.Download a released version or a snapshot from /exmpp.Can be browsed online at ProcessOne forge or download with: Old Subversion repository is still available for historical reasons, but not updated anymore.Git clone git:///exmpp/mainline.git exmpp Git repository with the development source code, see exmpp Git repo or exmpp on GitHub:. ![]() Source packages of released versions and daily snapshots are available at /exmpp. More helpers for writing pubsub clients.More code helpers (for example for Multi-User Chat packets (MUC)).The benefit is bigger for real life system, as the internal structure of exmpp are atoms and binaries. The result of the parse is dropped immediately. This comparison takes only the parsing consumption into account not the processing of the result. Memory consumption and CPU consumption is very stable, compared to both ejabberd and previous version of exmpp. This graph shows the memory consumption of the parser for 900 parsers doing 1000 small XML parsing each. Several different XML parsers can be used (expat, libxml2).It can be used to write a highly scalable XMPP proxy or XMPP server. Based on Erlang atoms and binary to limit memory consumption.Support for both formating of client and server packets.The programming style is close to Erlang approach and lead to very short pieces of code. Based on Erlang message reception and pattern matching. ![]() # You can put here as many accounts as you want.Exmpp is a fast and scalable library for the Extensible Messaging and Presence Protocol ( XMPP) written in Erlang/OTP. = #' ACCESS CONTROL LISTS acl: # The 'admin' ACL grants administrative privileges to XMPP accounts.
