Success stories 



The current version 2.3.13 (released on Sep 4, 2008) runs on Sun Solaris, IBM AIX, HP-UX, GNU/Linux, Digital Unix, Ultrix, Darwin/MacOS X, Windows NT and PocketPC and it should not be too difficult to port it to other platforms.


IPv6 support for MICO is in beta stage. We are looking for sponsors who would fund its completion. Please contact me if you are interested.

The following tools are necessary to compile MICO:

    Note: if you would like to build multi-threaded enabled build, which is now default option, then instead of gcc 2.95 you have to use at least gcc 3.2. Multi-threaded MICO compiled by gcc 2.95 is not stable, because of some bugs in this compiler.
