This is an experimental repository for Meterpreter source code as a separate entity from the Metasploit Framework. See the meterpreter-submodule branch at: rapid7/metasploit-framework@43f7d88ca7

Building - POSIX

You will need:

A compiler toolchain (build-essential package on Ubuntu)
gcc-multilib, if you're building on a 64-bit machine
jam
wget
patience and luck

Meterpreter requires libpcap-1.1.1 and OpenSSL 0.9.8o sources, which it will download automatically during the build process. If for some reason, you cannot access the internet during build, you will need to:

wget -O posix-meterp-build-tmp/openssl-0.9.8o.tar.gz http://openssl.org/source/openssl-0.9.8o.tar.gz
wget -O posix-meterp-build-tmp/libpcap-1.1.1.tar.gz http://www.tcpdump.org/release/libpcap-1.1.1.tar.gz

Note that the 'depclean' and 'really-clean' make targets will delete these files.

Building - Windows

You will need:

Visual Studio 2010
luck and patience
