See the official compiling howto: http://www.extatic.org/uhub/compile.html
Prerequisites
Before you try to compile µHub, please make sure the following prerequisites are met.
* GNU make
* gcc > 3.0 (or MinGW on Windows)
* libevent >= 1.3
* Perl 5
* openssl > 0.9.8 (or use "make USE_SSL=NO")
* sqlite > 3.x
or read https://www.uhub.org/compile.php for more info.
Linux, Mac OSX, FreeBSD, NetBSD and OpenBSD
-------------------------------------------
Linux and Mac OSX
-----------------
Simply, run:
% make
FreeBSD, NetBSD and OpenBSD
---------------------------
Use GNU make, not BSD make:
% gmake
If you have an old gcc compiler, try disabling pre-compiled headers like this:
gmake USE_PCH=NO

If you are planning to more than 1024 users on hub, you must increase the max number of file descriptors allowed.
This limit needs to be higher than the configured max_users in uhub.conf.
In Linux can add the following lines to /etc/security/limits.conf (allows for ~4000 users)
* soft nofile 4096
* hard nofile 4096
Or, you can use (as root):
% ulimit -n 4096
You can interact with uhub in your hub main chat using the `!` prefix, followed by a command:
Example :
* to display help and the command you can use:
!help
