Hi all,
i have some doubt in this topic
i have read that , it is due to
that the problem was that the appropriate "-debug" packages for the shared libraries were not installed and suggested that the absence of specific information as to which libraries were missing was a bug.
when i try to debug my pgm
Starting program: /home/shamjs/source/olupxtest

Breakpoint 1, main () at olupxtest.cpp:376
376             nError = olxGetAvailableModels(pred, sfileName, "", &nmodcount, &pointer);
(gdb) step
377             if(nError == OK)
(gdb) n
388             nError = olpSelectProjectFile(pred, sfileName, smodelName, "");
terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_S_construct NULL not valid

Program received signal SIGABRT, Aborted.
0x00110402 in __kernel_vsyscall ()
1>my question is that,whther it(warnings) cause any any problem to my program

2>im not able to use step during debugging ,as you can see i have applied break point at line 376 ,and then im trying to step into the olxGetAvailableModels function,but unfortunately stepping is not happening........(whether its because i got those warnings?)

what can be done........
waiting for your reply.......
