Error installing NS2.26 on Debian

colinlocal · #1 12-Jul-2008, 08:34

Hi All,
I am also trying to install NS2.26 and encountering some problems.
Some Info
Latest version of Debian.
Used instructions from Mathew Miller
http://www.matthewjmiller.net/howtos/ns-2-26-install-in-debian/
Compiling using gcc 2.95

I get an error during the compilation of NS2.26 stating
checking XOpenDisplay in -lX11... (cached) no
can't find X library
Ns configuration failed!

I have installed the below
apt-get install libstdc++2.10-glibc2.2
apt-get install libx11-dev
apt-get install libxt-dev

Has anybody any idea what I am missing on my installation.

Many thanks

Colin

I don't have Debian, but I have Ubuntu, which is based on, and closely related to, Debian. After installing Ubuntu and installing the libX11-dev and libxt-dev packages the ns installation (using the current version if ns all-in-one) went to completion with no problems.

I can't believe that you would have to down-rev gcc to the old, buggy 2.95 (I have had more problems with versions of 2.95 on embedded Linux projects then with any other GNU release of anything, anywhere, any time). I mean, I believe it if someone said he/she had to do it for the older version of ns, but hope that's not really necessary. I'm guessing that it wasn't the ns base code that gave the problems but compatibility problems between older X11 libraries and newer libgc libraries.

Why don't you download the latest version of the NS allinone (version 2.33 from http://www.isi.edu/nsnam/ns/ns-build.html#allinone), and then just untar it and cd into ns-allinone-2.33 and enter the following on the command line:

Code:

./install >install.log 2>& 1

This creates a file named install.log that will have a record of what went wrong and where. You can watch the install process "live" by opening another command window and navigating to the ns installaton directory and entering the following:

Code:

tail -f install.log

Ctrl-C exits the "tail" process.

If for some reason you are absolutely required to install some other version, then do the same command line stuff that I showed above. If the installation fails, then paste stuff from the install.log. Paste the lines before the first X11 warning or error messages into your post.

Regards,

Dave

Footnote: Since I don't have access to any Debian systems (I have access to one Ubuntu 8.04 platform but most of the ones for which I have administration privileges are Centos 5.2), you will be debugging the installation, not me.

It's always OK to ask about what you don't understand, but since I won't be able to reproduce your exact problems, it may take a few iterations. My point is that you should look at the messages in install.log, and try to understand and take corrective action. If you want to get help in timely fashion, It is extremely important that you post exact error/warning messages rather than paraphrasing. Just paste them into your post.

First of all, try it with the default version of gcc that was installed with your system, not gcc-2.95 (Tell us what version it is by entering "gcc --version" on a command line.)

Hi,

Thanks for looking at this. Unfortuntately I need to use version 2.26 as there are a few modules that apparently only run on this version. I have also been told that I need to compile it with gcc 2.95, and have libX11-dev and xlibs-dev installed on the system

The error occurs during the install of NS2.26, after the successful compilation of previous parts. No compilation of NS2.26 occurs as it is checking the environment for the correct bits ( I think!).

I used

Compiled with gcc 2.95.4. The other successfully compiled parts had many warnings - "negative integer implicitly converted to unsigned type"

Getting the previous parts (tk, tcl, tclcl) installed is major step, and that's probably what requires the old gcc (In particular, tclcl was problematic, as I recall). Believe it or not, I think you may be well on your way. (But I could be wrong, of course.)

They "probably" won't be a problem, and they "certainly" won't interfere with other compilation steps.

The messages were printed from ns-2.26/configure, which was run from the top-level configure program (assuming you are doing the "allinone" thing).

Instead of running everything from the top level from now own, cd into the ns-2.26 directory and run

Code:

./configure >configure.log 2.& 1

If you look in the configure file in ns-2.26, you should see where it is testing for the x11 library; It is probably looking for /usr/lib/libX11.a and/or /usr/lib/libX11.so

The first thing is for you to find out whether they are there:

Code:

ls -l /usr/lib/libX11.a
ls -l /usr/lib/libX11.so

If they are there but the configure script didn't find them, then you have to figure out where it is looking. (You may have to do some detective work inside ns-2.26/configure.)

If they are not there, then try the following from a command line:

Code:

whereis libX11

If it shows locations for libX11.a and/or libX11.so, and they are not in /usr/lib, then you will have to tell the configure script where to look

There should be a run-time option to the configure script that lets you do that.

Since I don't the exact installation that you have, there will be more detective work at this point.

Let us know what you see.

Regards,

Dave

Hi,
Thanks for the reply.
The Xlibrary files are in /usr/lib/

I can't figure out where the configure is looking from them, or how to force it to look in /usr/lib

Code:

configure:3318: checking for XOpenDisplay in -lX11

Line 3318 from configure

Code:

ac_lib_var=`echo X11'_'XOpenDisplay | sed 'y%./+-%__p_%'`

Other surrounding code from the configure file

Code:

echo "checking for X11 library archive"
if test "$x_libraries" = NONE ; then
	echo $ac_n "checking for XOpenDisplay in -lX11""... $ac_c" 1>&6
echo "configure:3318: checking for XOpenDisplay in -lX11" >&5
ac_lib_var=`echo X11'_'XOpenDisplay | sed 'y%./+-%__p_%'`
if eval "test \"`echo '$''{'ac_cv_lib_$ac_lib_var'+set}'`\" = set"; then
	 echo $ac_n "(cached) $ac_c" 1>&6
else
 ac_save_LIBS="$LIBS"
LIBS="-lX11  $LIBS"
cat > conftest.$ac_ext <<EOF

Many thanks
Colin

Hi,
I have solved this problem! And NS2.26 has installed! But now it fails on installing NAM (the visualizer).

The solution was from some other instructions that I was using. Mentioning that Debian is similar to ubuntu, I checked some install instructions for ubuntu and found that "Ubuntu uses x.org and not XFree.org", so I need to create some symbolic links.

Code:

ln -s /usr/lib/libX11.so.6.2.0
ln -s /usr/lib/libX11.so.6
ln -s /usr/lib/libX11.a
ln -s /usr/lib/libX11.so

This solved the problem.

The problem with NAM is

Code:

rm -f xwd.o; /usr/bin/gcc-2.95 -o xwd.o -c  -DTCL_TK  -DNDEBUG -DUSE_SHM -DHAVE_LIBTCLCL -DHAVE_TCLCL_H -DHAVE_LIBOTCL1_0A8 -DHAVE_OTCL_H -DHAVE_LIBTK8_3 -DHAVE_TK_H -DHAVE_LIBTCL8_3 -DHAVE_TCL_H  -I. -I/usr/local/dload2/ns-allinone-2.26/tclcl-1.0b13 -I/usr/local/dload2/ns-allinone-2.26/otcl-1.0a8 -I/usr/local/dload2/ns-allinone-2.26/include -I/usr/local/dload2/ns-allinone-2.26/include  xwd.c
xwd.c:87: X11/Xmu/WinUtil.h: No such file or directory
make: *** [xwd.o] Error 1
Nam make failed! Continue ...

Do you think that this is also related to x.org being used instead of XFree.org?

Many thanks
Colin

I'm glad, because I was just about to say that I was almost out of "remote control" ideas.I mean, poking around on my own system, sometimes I try a million things (maybe more) before I stumble across one that works. It's kind of hard to go through all of that with someone with a different operating system who is installing a different software version.

Congratulations!

I am not at a place where I can access Ubuntu, but I know that in Centos (RedHat) distributions, there is a "libXmu" package available that creates and populates the Xmu directory and Xmu library functions. Try to find it with your apt package manager. If you havd the GUI apt package manager, just search for "Xmu". (Or go back to some Ubuntu forum and search there.) I'm thinking that you need both "libXmu" and "libXmu-devel."

Now, if you already have /usr/include/X11/Xmu/WinUtil.h, then you may have to do something similar to what you learned about the ns installation (I don't understand exactly where you made links, but it's not important for me; only for you. I couldn't offer more advice on that anyhow.)

Regards,

Dave

Thanks Dave,

Installing this works! NS and NAM are now working like a dream.

In short, for all those students show need to install NS2.26 as they have written loads of code for it, or use a module that only works with this (MNS), this will work.

Install Debian 4.0r3

Carry out instructions from
http://www.matthewjmiller.net/howtos/ns-2-26-install-in-debian/

In addition
Create symbolic links in /usr/X11R6/lib
ln -s /usr/lib/libX11.so.6.2.0
ln -s /usr/lib/libX11.so.6
ln -s /usr/lib/libX11.a
ln -s /usr/lib/libX11.so

in /usr/bin create a symbolic link
ln -s g++-2.95 c++

Additional apt-get for NAM
apt-get install libxmu-dev

Many thanks for the help.

Colin

Well, what goes around comes around. See References.

You can be sure that people will be helped by your sharing. I'll bet that at least some of them will, in turn, go on to help others. They may even help you some day. (Me too.)

And so it goes...

Dave
