You can resolve this in several ways: Use g++ in stead of gcc: g++ -g -o MatSim MatSim.cpp Add -lstdc++: gcc -g -o MatSim MatSim.cpp -lstdc++ Replace <string.h> by <string> This is a linker problem, not a compiler issue. The same problem is covered in the question iostream linker error – it explains what is … Read more
You just need a binary (with debugging symbols included) that is identical to the one that generated the core dump file. Then you can run gdb path/to/the/binary path/to/the/core/dump/file to debug it. When it starts up, you can use bt (for backtrace) to get a stack trace from the time of the crash. In the backtrace, each function invocation is … Read more
This bellow code will generate Aborted (core dumped) at last line. code: output is: Here I’m interested to know in which cases these core dumped will occur? Can we find out at which line this is occurred without using debugger? what information it is showing(about shared libraries)?
The problem is here: Basically, when you free temp2, you free first, not the memory allocated here: , which remains a memory leak, because after the assignment it can’t be freed anymore. Also, your code has probably some more problems (one is that you shouldn’t use fflush on an input stream), but without some more details, it’s … Read more
You’re probably dividing by zero or some other nonsensical number. Are you sure real and imag for IFFTOutput[i] isn’t zero? Print it out just before perhaps?
You are getting Floating point exception because Number % i, when i is 0: Just start the loop at i = 2. Since i = 1 in Number % i it always be equal to zero, since Number is a int.
Two things I see. First, you’re mixing chars with ints in the matrix array. Second, you’re printing the elements of matrix out to a file using the “%s” format. “%s” expects a null-terminated string where as you are passing chars and ints. This will cause the printf to try and access memory that is out-of-bounds, … Read more
