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
Code:
user/run/run.sh
, which runs the project binary in
Code:
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
Code:
*** No targets specified and no makefile found. Stop.
"
I then set the size limit of core files by
Code:
ulimit -c 75000
But when I enter
Code:
gdb /user/project/Build/bin/project core
I get
Code:
gdb /user/project/Build/core: No such file or directory.
When I enter
Code:
bt
, I get
Code:
No stack
When I then use the command prompt to go into directory
Code:
/user/project/Build/bin
and then type
Code:
gdb project
and then "run", I get
Code:
Thread debugging using libthread_db enabled.. Program exited with code 01.Missing separate debuginfos,
use: debuginfo-install glibc-2.12-1.149.el6_6.4.x86_64 libICE-1.0.6-1.el6.x86_64 .
..
What am I supposed to do to detect the segmentation fault?
Well, 'core' is a real file, somewhere, and it has to be produced (by allowing configuration) and properly pathed for gdb to open it. The dying process puts it in $PWD/core. Once gdb is up, 'where' will get you down to a subroutine. Of course, you need source and it helps if the compile options and lack of stripping make the crashing object easy to debug. Sometiems fate is cruel, and it only bombs if you compile it without symbols! There is also running it under truss/tusc/strace to get some idea of what calls preceded the crash.

If I do this.
Assume
struct life

}
struct life **life;
// malloc initialization & everything
if(life->nolife == 0)
Would I get error at life->nolife if it is equal to 0.
