P2P NAP的C实现 P2P在网络应用中越来越流行

WHAT TO DO WHEN NCURSES IS MISSING.

Nap needs a screen handling package called "ncurses". Some operating
systems do not come with ncurses installed. Notably, this is the case
for Solaris and for MacOSX. In these cases, you need to install
ncurses yourself. Here are some instructions. When in doubt, or if
something is not working, please refer to the instructions that come
with the ncurses package.

Note: some binary distributions of nap come with a file called
ncurses.so.5 or similar. If you are installing nap from a binary
distribution, see BINARY DISTRIBUTIONS below. The following
instructions are for those who want to compile nap themselves.

IF YOU HAVE ROOT PRIVILEGES:

1) Download ncurses-5.2 (or later) from www.gnu.org. At the time of
   this writing (December 2002), the correct URL is
   http://www.gnu.org/directory/GNU/ncurses.html.

2) From the main ncurses directory, run the following commands:
   
   ./configure --with-shared --without-debug
   make
   make install.libs

   If you want to build your own terminfo database, run

   make install.progs
   make install.data

   If you want to install the man pages (there are thousands of them), 
   run

   make install.man

3) Compile nap: From the main nap directory, do "./configure",
   followed by "make", followed, optionally, by "make install". 
   See the NOTES below for some hints on running nap.

IF YOU DO NOT HAVE ROOT PRIVILEGES:

1) Download ncurses-5.2 (or later) from www.gnu.org. At the time of
   this writing (December 2002), the correct URL is
   http://www.gnu.org/directory/GNU/ncurses.html.

2) Create an empty directory $foo somewhere in your private file
   space. Then run the following commands from the main ncurses
   directory:

   ./configure --prefix=$foo --with-shared --without-debug
   make
   make install.libs
   
   If you want to build your own terminfo database, run

   make install.progs
   make ticdir=$foo/lib/terminfo install.data

   If you want to install the man pages (there are thousands of them),
   run 

   make install.man

3) Compile and link nap with the following command:

   make CFLAGS="-g -O2 -I$foo/include" -L$foo/lib"

   Every time before running nap, you must set the shared library path
   for the dynamic linker, and you must tell ncurses where to look for
   your terminfo database (if you built your own terminfo database):

   (if you are using sh or bash:)
   export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$foo/lib"
   export TERMINFO=$foo/lib/terminfo

   (if you are using csh or tcsh:)
   setenv LD_LIBRARY_PATH "$LD_LIBRARY_PATH:$foo/lib"
   setenv TERMINFO $foo/lib/terminfo

   See NOTES below for some hints on running nap.

BINARY DISTRUBUTIONS:

If you obtained a binary distribution for nap which came with the file
ncurses.so.5 or similar, and if nap complains that it cannot find this
file, you need to do one of two things:

a) put the file ncurses.so.5 somewhere where the dynamic linker looks
for shared libraries, typically /usr/lib or /usr/local/lib, or

b) set the LD_LIBRARY_PATH environment variable to contain a path to
the directory $lib which contains the ncurses.so.5 file:

   export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$lib"  (for sh and bash)
   setenv LD_LIBRARY_PATH "$LD_LIBRARY_PATH:$lib"  (for csh and tcsh)

You need to set LD_LIBRARY_PATH each time you want to run nap, unless
you put the above commands in your .bashrc or .tcshrc file.

Important: the ncurses.so.5 file distributed with nap assumes that
your terminfo database is located at /usr/share/lib/terminfo. If it is
in a different location, you must set the TERMINFO environment
variable to the location, e.g.

   export TERMINFO=/usr/share/terminfo

NOTES ON RUNNING NAP:

On some systems, if nap runs in an xterm, it will run in black
and white, without color support. You may be able to enable color by
setting the TERM environment variable to "xtermc".

Also, not all keys may behave properly. For instance, the arrow keys,
PgUp and PgDn keys, and/or F1-F3 keys may not work as desired. I am
not sure why this is the case. Use 'q' instead of F1, "/results"
instead of F2, and "/dlul" instead of F3.
