To use acarsd the following library are required:

Under Windows:
--------------
wininet.dll	comes with the Internet Explorer
winmm.dll	multi media lib. Should be installed on every system


Under Linux:
------------
libpthread.so	PThreads
libncurses.so   NCurses (Version 5 or higher)
libz.so		ZLIB compression library (www.zlib.org)
libm.so		Should be installed on every system
libc.so.6	Standard C library
libuuid.so      Unique ID's (UUID) (comes with E2fsprogs)

libtcl8.4	Tcl library (www.tcl.tk)
libtk8.4	Tk library (www.tcl.tk)

(Compiled against Tcl/Tk 8.4 Patchlevel 1)

PLEASE NOTE THAT ACARSD REQUIRES ALSO THE libacarsd.so WHICH IS PROVIDED
WITH THE ACARSD ARCHIVE

***********************************************************************
 UNDER LINUX THE EXECUTABLE CANNOT ACCESS LIBS FROM THE SAME DIRECTORY 
                        WITHOUT ANY CHANGES!
***********************************************************************

First way:
----------
Modify your LD_LIBRARY_PATH

set LD_LIBRARY_PATH = "./" or "/home/acarsd/"

Second way:
-----------
Copy libacarsd.so to one of the default library folders

cp libacarsd.so /lib/
  or
cp libacarsd.so /usr/lib/

You can call the 'ldd' so see that acarsd can find all needed libs:
Call: ldd ./acarsd
You should see output like the following:

  ldd acarsd
	libncurses.so.5 => /lib/libncurses.so.5 (0x40028000)
	libz.so.1 => /lib/libz.so.1 (0x40072000)
	libuuid.so.1 => /lib/libuuid.so.1 (0x4009d000)
	libpthread.so.0 => /lib/libpthread.so.0 (0x40081000)
	libacarsd.so => /lib/libacarsd.so (0x40097000)
	libc.so.6 => /lib/libc.so.6 (0x400a5000)
	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
