my friend iam installing ns-2.34 which is needed to install ns-2.27 by follow the steps in post #3 for knudif until i reach patching step i faced this probelm
foad@foad-laptop:~$ cd ns-allinone-2.27
foad@foad-laptop:~/ns-allinone-2.27$ cd tk8.4.18
foad@foad-laptop:~/ns-allinone-2.27/tk8.4.18$ patch -p0 < tk-8.4-lastevent.patchbash: tk-8.4-lastevent.patch: No such file or directory
foad@foad-laptop:~/ns-allinone-2.27/tk8.4.18$
it seems that tk8.4.18 does not found and iam sure its exist.
iam waiting response please

It can't find the patch file. Is the patch file in the tk8.4.18 directory? The command that is failing is written as if the patch file is in the tk8.4.18 directory.

Easier this way :

cd ns-allinone-2.27/tk8.4.18/ &&
wget ftp://ftp.swin.edu.au/gentoo-portage...astevent.patch
&& patch -p0 < tk-8.4-lastevent.patch

.. Then you are sure that "tk-8.4-lastevent.patch" is in the current directory.

.

iam still suffring from this problem "patching".
iam fellow the last step but is still found the same error please knudfi iam waiting...
also in patching with otcl-1.13
this error
bash: otcl-113-configure.in.patch: No such file or directory
now suggest any method to patch.

here are the output when i perform the last post.

bash: syntax error near unexpected token `&&'
foad@foad-laptop:~/ns-allinone-2.27/tk8.4.18$

The && types are used, when you have more than one command in one line.
The "single command" is : patch -p0 < tk-8.4-lastevent.patch

( The command can be
cd ns-allinone-2.27/tk8.4.18 && patch -p0 < tk-8.4-lastevent.patch
... if the patch is present in tk8.4.18/ ).
