Segmentation fault (Core dumped)

[mounamouna]

I have Ubuntu 13.0 in Vmware player. I installed FastPFor library by executing: Cmake . make After that, I tried to run the example.cpp but this error was occured: Segmentation fault( Core dumped). What is the problem and how can i correct it?????,

[searchivarius]

example.cpp is not an executable.

[mounamouna]

I write in the terminal: make example.cpp the result: Segmentation fault( Core dumped)

[searchivarius]

Please, check the README. You don't need to type ``make example.cpp''.

@mounamouna

I think that you mean that you typed:

        $ cmake .
        $ make
        ./example

and then you got a segmentation fault.

If that is the case, please follow the following instructions:

        $  uname -a
        $ g++ --version
        $ cat /proc/cpuinfo | grep model
        $ cmake .
        $ make
        $ ./unit
        (if unit tests do not complete successfully, please report the error)

If you get a segmentation fault, please type:

        $ gdb ./unit
        gdb> run
        (example will stop at the segmentation fault if any)
        gdb> where
        gdb> list

Then and only then...

        $ gdb ./example
        gdb> run
        (example will stop at the segmentation fault if any)
        gdb> where
        gdb> list

Please provide a complete output including everything you typed and everything that appeared on screen.

@mounamouna

Very useful thank you. This code should run on your machine and you do what is needed. So this looks like a bug. Unfortunately, I cannot reproduce it and nobody else here can either.

We need more information. So the next logical step is to build the software in debug mode. This should help.

We now know that the segmentation fault seems to happen in the constructor of VarIntG8IU(). Let us narrow it down.

Please do the following:

    $ git pull
    (please sync with the very latest version as to enable debugging was difficult previously)
    $ cmake -DCMAKE_BUILD_TYPE=Debug .
    $ make
    $ gdb ./unit
    gdb> run
    (unit will stop at the segmentation fault if any)
    gdb> where
    gdb> list

Please note that your help is necessary at this point.

Normally one acquires the code from this project for GitHub. As things stand, it is difficult to tell which code you are testing.

Please recover the latest version of the code like so:

      $ git clone https://github.com/lemire/FastPFor.git
      $ cd FastPFor
      $ cmake -DCMAKE_BUILD_TYPE=Debug .
      $ make
      $ gdb ./unit
      gdb> run
           (unit will stop at the segmentation fault if any)
      gdb> where
      gdb> list

and work from there. By issuing a "git pull" in the future will allow you to recover the latest version of the code from GitHub.

As a further sanity test, please run...

      $ ulimit -s
      the answer should 8192

I find that my gcc version (4.8) has a problem with these instructions :

endif

How can I modify this part of code for adapting it to gcc-4.8 ?

• In a previous comment, you indicated using GCC 4.8 under Linux and it compiled. Your problem was a crash of the compiled code.
• Right now, it appears that your code does not to compile at all.

You have not commented on this change in the nature of the problem. It would be nice if you could explain this change: how could the code compile before? That seems a bit suspicious.

You are using GCC 4.8 under Linux. We are also using GCC 4.8 and this code is fine. This is a conventional piece of assembly that abides by the specification, as far as I can tell.

Please give me a complete print out of everything you did from the beginning as I requested: (Please, you need to give us a complete print out...)

      $ mkdir newtmp
      $ cd newtmp
      $ uname -a
      $ gcc --version
      $ ulimit -s
      (the answer should 8192)
      $ git clone https://github.com/lemire/FastPFor.git
      $ cd FastPFor
      $ cmake -DCMAKE_BUILD_TYPE=Debug .
      $ make VERBOSE=1
      $ gdb ./unit
      gdb> run
           (unit will stop at the segmentation fault if any)
      gdb> where
      gdb> list

The output should be as follows... notice that in this particular instance, I am using GCC 4.8 and the code builds and run just fine:

• In a previous comment, you indicated using GCC 4.8 under Linux and it compiled. Your problem was a crash of the compiled code.
• Right now, it appears that your code does not to compile at all.

You have not commented on this change in the nature of the problem. It would be nice if you could explain this change: how could the code compile before? That seems a bit suspicious.

You are using GCC 4.8 under Linux. We are also using GCC 4.8 and this code is fine. This is a conventional piece of assembly that abides by the specification, as far as I can tell.

Please give me a complete print out of everything you did from the beginning as I requested: (Please, you need to give us a complete print out...)

  $ mkdir newtmp
  $ cd newtmp
  $ uname -a
  $ gcc -version
  $ ulimit -s
  (the answer should 8192)
  $ git clone https://github.com/lemire/FastPFor.git
  $ cd FastPFor
  $ cmake -DCMAKE_BUILD_TYPE=Debug .
  $ make VERBOSE=1
  $ gdb ./unit
  gdb> run
       (unit will stop at the segmentation fault if any)
  gdb> where
  gdb> list

The output should be as follows... notice that in this particular instance, I am using GCC 4.8 and the code builds and run just fine:

@mounamouna

Have you found out why you were able to compile the code before?

I just noticed that you appear to be running a 32-bit OS. Is there any particular reason for this choice? This software assumes a recent 64-bit system. You should still be able to cross-compile a 64-bit binary, but this may require some work on your part. The simplest path would be to use a 64-bit system.

I would be interested in the output of this command:

               $  gcc -march=native -dM -E - < /dev/null

[lemire]

I am going to close this issue since I do not think it is reasonable to support 32-bit systems.

Thanks for all your feedback and sorry for not catching up earlier on the issue.

Please upgrade to a 64-bit system. If the problem still persists, I will be glad to help further.

[mounamouna]

Sir, I don't compile this code before. mouna@ubuntu:~$ gcc -march=native -dM -E - < /dev/null

Please Sir, can you help me. For my thesis work, I installed NS3 simulator in this system in order to implement a proactive solution for ip traceback in wireless mesh networks. So i couldn't change completly the system but i want to integrate this package FastPFor in my ns3 implementation because i need to compress two successive ipv4 addresses in one address(using this library and another technics). How can i transform my system to 64-bit system, if possible??

Thanks in advance.

Have you found out why you were able to compile the code before?

I just noticed that you appear to be running a 32-bit OS. Is there any particular reason for this choice? This software assumes a recent 64-bit system. You should still be able to cross-compile a 64-bit binary, but this may require some work on your part. The simplest path would be to use a 64-bit system.

I would be interested in the output of this command:

           $  gcc -march=native -dM -E - < /dev/null

Is your NS3 implementation requiring you to have a 32-bit system? I would think not.

The simplest thing would be reinstall your operating system, and choose a 64-bit version of Ubuntu. Frankly, you have to go out of your way to install a 32-bit Ubuntu these days. Unless you have old hardware (or old binary software), it makes little sense to have a 32-bit version of Ubuntu. You do not appear to have old hardware... so why are you using a 32-bit version of Ubuntu?

[mounamouna]

I think #19 (comment) https://github.com/lemire/FastPFor/issues/19#issuecomment-93853901 is another version of FastPFor (I will try to find it), but the newest one given by "git clone https://github.com/lemire/FastPFor.git" don't work for me. I installed ubuntu 13.0 in Vmware Player (in windows 7). Initially, i don't care about the system type 32-bit or 64-bit just i think about installing NS3 simulator in my machine. The installation of this simulator was very difficult and took a lot of time.

I am able to cross-compile a 32-bit binary on my 64-bit OS (using GCC's -m32 flag). I am thus perfectly able to reproduce your problems now. If you type cmake -DCMAKE_BUILD_TYPE=Debug ., you end up with the compilation error your just described. If you just do cmake ., then you end up with a segmentation fault in FastPForLib::VarIntG8IU::VarIntG8IU() ().

So it seems like everything is explained: the problem is with the fact that you have a 32-bit system. You need to upgrade to a 64-bit system.

Thanks for the bug report, we have upgraded the documentation to make sure that people know that a 32-bit system is required.

The installation of this simulator was very difficult and took a lot of time.

I am sure it was.

Supporting 32-bit systems in FastPFor would be very difficult and take a lot of time.

So it seems like either you upgrade your system to a 64-bit system... which, I am sure, is going to take you a couple of days... or you find someone willing to spend the necessary time to make FastPFor run on 32-bit systems. As I just wrote, I do not consider this task to be a reasonable one... but you might find someone who is willing to spend the time. Of course, it might help if you were willing to pay for the work in question.

Good luck!

What is the problem???

You have a 32-bit system. This is not supported.

I have modified the cmake script so that it warns you if you do not have a 64-bit system.

The problem is that i have to reinstall all things Ubuntu NS3 eclipse . . . FastPFor :( Return to the step zero

You can use simpler libraries...

Please have a look at the actual line 277 in unit.c of the project your refer to :

https://github.com/lemire/simdcomp/blob/master/src/unit.c#L277

[mounamouna]

I modified this line but the same error: mouna@ubuntu:~/simdcomp-master$ make cc -fPIC -std=c89 -O3 -march=native -Wall -Wextra -pedantic -o unit ./src/unit.c -Iinclude simdbitpacking.o simdintegratedbitpacking.o simdcomputil.o simdpackedsearch.o simdpackedselect.o mouna@ubuntu:~/simdcomp-master$ make test ./unit gap = 1 make: *\ [test] Segmentation fault (core dumped)

@mounamouna

I am not sure you understand how this is supposed to work. I recommend you read up on GitHub and how it works. You should probably familiarize yourself with the culture of open source as well.

@mounamouna

Just a few pointers on the culture of GitHub:

• You are supposed to clone the code from GitHub and make sure your code is identical.
• If you find a problem, you are supposed to carefully document it and produce a reproducible test case or submit a patch (through a fork).

About open source:

• Open source is not a system where you are can get free support. Please do not do this. For your own good. Please do not assume that other people's time is less valuable than yours, if you care at about your reputation.

just one question: it is compatible with my 32-bit system??

Probably not, but as Daniel pointed out, we have no time/desire/incentives to figure this out. In that, reinstalling your virtual system takes very little time.

I am sorry Sir for wasting your time. You are a gentil man.

@mounamouna The C library simdcomp should run on a 32-bit system. It is very simple C code with nothing fancy. Of course, you need to run it from a fresh clone, not some hand-modified version. It is also probably entirely useless to compress IP addresses, but that is another story.

As @searchivarius pointed out, reinstalling your virtual system so that it is 64-bit (as it should IMHO) takes very little time compared to the effort needed to make complex 64-bit code run on 32-bit systems. Compared to the effort needed to test and integrate something like FastPFor in a software implementation... installing a 64-bit OS is a walk in the park.

[mounamouna]

Thank you Sir.
