Ex: Compiling a cpp file using a basic command "g++ filename.cpp" and to run the program use ./a.out, Then to store the compilation error to text file use this command. g++ test.cpp > log.txt log.txt contains the compile time errors.

If your code is giving core dump or segmentation fault then the easiest way to debug the error is using the gdb and file created by coredump.

example: use this command to compile the code
$ gcc -g -o outfile sample.cpp

use this command to run this.

$ ./outfile -- if you get message segmentation fault or core dump then look for the coredump file created in perticular folder the use following
command to debug it.

$gdb coredumpfilename --- this will display where exactly code is created a dump.

You can use 'bt' command to back trace the error.


enjoy error free coding ............
