I am using scientific linux. In the directory user/project/Build, after I ran 'make' to compile and link all the cpp files,I had no problems. But then, when I went to directory user/run/run.sh, which runs the project binary in user/project/Build/bin/project, I get a segmentation fault error. In the directory user/run, I enter 'gdb' in the command prompt and get the message "*** No targets specified and no makefile found. Stop."
What am I supposed to do to detect the segmentation fault?

First time post so I hope it's not too long winded!
I've just installed Centos v7.1 and created an additional user.
First putty session I logged in with root and got the public fingerprint message and clicked Yes to accept.
However I noted when I logged in with the user other I did not get the prompt and my home directory didn't have a .ssh directory.
OK, so I created a .ssh (chmod 700) directory within /etc/skel and created a new user. Logged in with that account and still no prompt, although I do now have a .ssh directory generated.
I've tried deleting the known_hosts files in the root's .ssh directory and restarting the sshd daemon but it's not working.
How do I get it to prompt with original public key again?
Thanks for reading.
i had added my own red.cc to ns2.34 when i run the tcl script it runs correctly, but after adding my own varible to red.cc and red.h the tcl script showing segmentation fault

hi,
I'm cross-compiling a linux kernel. And I want to use git to manage the project. When I first add the project to the git index and commit, then I clone it out, I failed to compile it with the file missing information printed. The file missing is like include/linux/autoconf.h amount many others.
PS:I have no gitignore in the current directory.
Please take a look and give some hints if anyone has some thoughts.
Thanks.
I am working on LAR protocol, ns2 version = 2.32
OS = ubuntu 12.04
i successfully installed LAR NS on my system . but nam does not qork with ns-2.32 . so i tried to install with the following command
sudo make install nam ===> it successfully installed namv1.15 . but when i run box.tcl it is giving me the following error
SORTING LISTS ...DONE!
channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5, distCST_ = 220.0
Segmentation fault (core dumped)
then i tried to remove the nam with this command sudo apt-get remove nam ==> removed
then i installed this nam from (nam_1.14_amd64.deb) . when i write nam it shows me network animator window v1.14 but segmentataion fault error remains the same .
I also tried to install nam-1.14.i586.tar.gz , first untar it and then the following command sudo cp nam /usr/local/bin but still the error .
i also tried with nam-1.14-x86_64.tar.gz but still no success.
if i dont use nam , then my box file runs successfully.
plz suggest me how to rectify this error.
