gnu.linkonce undefined reference

newbie06 · #1 10-Mar-2007, 23:35

Hi all,

I am using ns2 as my simulator, but I think this problem is related with c++. I am facing a problem during compilation process in which I got several pages of errors. Some of them are listed below (I cannot paste all here because it is too long, howver, the errors are quite the same, complaining about the .gnu.linkonce and undefine reference):

Code:

sctp/mhsctp.o: (gnu.linkonce.d__vt-11MhSctpAgent+0x90): undefined reference to ‘sctpAgent::SendBufferDequeueUpTo(unsigned int)’

.
.
.
.
.
.

and so many more. Maybe hundreds of them. I dont understand why this happen. I am tired of correcting the errors!..

And one more thing is that during compilation, some of the files that have been declared in the Makefile.in have been deleted ( I don’t know why), and thus an error will be given, for instance as shown below:

Make: *** Cannot make the target rule of “sctp/sctp.o” needed by “sctp/sctp.cc” Stop.

I have checked in the /sctp and it was not there, so I have copied back the sctp.o file, then after recompile, and it keep complaining the same (because it is again deleted).
Even though one of the errors has been corrected, more errors will be generated after re-compile. I wonder why this happened and could not think else what is the solution.

does anybody have a clue why this is happen? Thanks in advance.

I am assuming that your original installation was successful and now you are compiling with some new code that you have added. If not, then tell us exactly what you have done up to this point.

If you have added some new stuff, exactly what did you change in the ns directories to get the new stuff there? Did you copy the entire ns installation tree somewhere else or are you doing your new stuff on top of the old stuff? (Either can be made to work, I think, but I usually create a new tree identical to the old one before making changes. That way I can always go back to the old one for testing.)

Did you do a "make clean" before "make" or what? In other words, how did you try to build the new stuff. (I recommend "make clean" at the top ns-... directory

What Linux distribution are you using?

At a Linux command line, what do you get when you enter "g++ --version". Some older versions of GNU compilers had problems with "#pragma installation" and gave the mysterious "linkonce" messages. (version 3.4.x or higher should be OK.)

How much code is in your new files? Can you post them?

When you do a "make", it needs to find the source files "something.cc" or "something.h" to create new files (the "something.o") stuff. Are all of your source files in place? Copying the "something.o" stuff is not the thing to do. Copy the ".cc" and ".h" files to the corresponding places in the new directories. (I just copy everything, then do "make clean".)

I can't reproduce your problems or give any specific help, since my installation is for the current version (ns-2.30), and it does not have mhsctp.cc. My directory name for the sctp stuff is "sctp" not "Sctp". It does not have mhsctp.cc or Mhsctp.cc or mhreg.cc

Dave

Hi Dave,

Yes u're right. After finished compiling the original installation, I added my codes on top of the original tree, and some of the original files have been replace with the new one such as Makefile.in, ns-default.tcl, ns-lib.tcl and many more, and the old file have been renamed to a new filename.

yes, I did 'make clean' after ./configure. After that only I do 'make'. All of the 3 commands were executed at ns-allinone-2.26/ns-2.26/

I am using Knoppix. Is it can contribute to the errors?

Quote:

This is what I got when i typed the above command:

Code:

g++ (GCC) 3.3.6 (Debian 1.3.3.6-7)
Copyright (c) 2003.............not even for MERCHANTABILITY/FITNESS FOR A PARTICULAR PURPOSES

..

U said version 3.4.x or higher should be ok..Is that means that my compiler is not compatible?

Quote:

ohh...there are so many files that I could not post it here. So many folders and inside one folders there are so many script files.

yeah..! U are right, I have misunderstood about this. I thought that the 'something.o' file is the file that we create. Thanks for make me clear.

Dave, after all, I have managed to solve all the problem above. I dont know, after I reboot into windows, and reboot back into linux, I recompiled again and all the errors dissappear, just as nothing happened before..so wierd!..It still got errors, but the small errors like undefined variables etc that I managed to solve. So could you please explain why this happened? It maybe happen again in future, so I need to know why..

ok, howevere, there are something wrong with the compilation result, as follows:

Code:

make[1]: Entering directory '/home/my/sproject/ns-allinone-2.26/ns-2.26/indep-utils/webtrace-conv/ucb'
make[1]: Nothing to be done for 'all'
make[1]: Leaving directory 'home/my/sproject/ns-allinone-2.26/ns-2.26/indep-utils/webtrace-conv/ucb'

my@box-ns2:~/sproject/ns-allinone-2.26/ns-2.26$ns
ns:
[code omitted because of length]
:invalid command name "Node/MobileNode/MhSatNode"
  while executing
"Node/MobileNode/MhSatNode instproc init args {

$self instvar id_ agents_ dmux_ address_ address1_ nodetype_

if {[llength $args] == 2} {
set address..."

Do you know what is the problem?
many thanks...

Ok..thanks in advance for your help..

I doubt it, but sometimes it might make a difference if we are using different distributions.

I don't know what versions were afflicted, but I think they might have been older than 3.3. Furthermore, the error only occurred under certain circumstances, and I don't know what the cause or the resolution was.

I thought so. It probably wouldn't do much good to post them, since other people would have a very hard time following them anyhow. You are probably already beyond my personal ability to help. (But keep asking --- there may be others who can help.)

It takes a little "getting used to".

I don't have any clues. However, in my experience, things that fix themselves now might 'un-fix' themselves later. Whether it was "cockpit error" or some vague, unpredictable "feature" of the tools. So, I understand your need to know; I just don't know how to get to the bottom of things from long distance.

Can't tell from here. Sorry.
