===== Uno a uno =====

Sigo http://wpage.unina.it/marcello.caleffi/ns2/fedora.html

He instalado algunos paquetes:

  aptitude install libx11-dev libxmu-dev libxmu-headers libxt-dev libtool

Instalo por este orden:

<code>
tcl
tk
otcl ./configure --prefix=/usr/ --enable-shared --with-tcl=/usr/local/src/ns2_a_mano/tcl8.4.19/
tclcl
ns2
nam
</code>

Siempre con la secuencia:

<code>
./configure
make
make install
</code>

Solo en los configures le tengo que pasar la ruta a tcl, pero de momento me funciona

**xgraph**

  ./configure

OK

  make


<code>

  make install

Al arrancar ns:

  ns: error while loading shared libraries: libotcl.so: cannot open shared object file: No such file or directory

No funciona:

  LD_LIBRARY_PATH+=/usr/local/src/ns2_a_mano/otcl-1.13/libotcl.so
  TCL_LIBRARY+=/usr/local/src/ns2_a_mano/tcl8.4.19
  TK_LIBRARY+=/usr/local/src/ns2_a_mano/tk8.4.19

Ahora cuando ejecuto nam:

<code>
nam:

    while executing
"bind Listbox <MouseWheel> {
%W yview scroll [expr {- (%D / 120) * 4}] units

    invoked from within
"if {[tk windowingsystem] eq "classic" || [tk windowingsystem] eq "aqua"} {

}
bind Li..."
</code>
  

===== Allinone =====

Please put:

<code>
/usr/local/src/ns-allinone-2.34/bin:/usr/local/src/ns-allinone-2.34/tcl8.4.18/unix:/usr/local/src/ns-allinone-2.34/tk8.4.18/unix
</code>

into your PATH environment; so that you'll be able to run

 itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put

<code>
/usr/local/src/ns-allinone-2.34/otcl-1.13
/usr/local/src/ns-allinone-2.34/lib
</code>

into your LD_LIBRARY_PATH environment variable.

If it complains about X libraries, add path to your X libraries into LD_LIBRARY_PATH.
If you are using csh, you can set it like:

  setenv LD_LIBRARY_PATH <paths>
  
If you are using sh, you can set it like:

  export LD_LIBRARY_PATH=<paths>

(2) You MUST put 

  /usr/local/src/ns-allinone-2.34/tcl8.4.18/library 

into your TCL_LIBRARY environmental variable. Otherwise ns/nam will complain during startup.

After these steps, you can now run the ns validation suite with

  cd ns-2.34; ./validate
