using gdb to debug

1. Compile Remove the strip from the compiled file (if Makefile contains) and add the-G option 2. Setting of environment variable The variable parameters that are entered by CGI are generally set by environment variables. This is the main difference between debugging CGI and debugging common C + + programs. The CGI input parameters, in CGI, are implemented by reading the environment variables. (1) can be set in the shell with export Onionxie@c2c_206_45_sles10sp1:~/c2cforcc/clubs/mcs/web/

The following example uses network debugging as an example. 1. Compile the application on the Linux host: bfin-uClinux-gcc-g-O0-o a. out test. c -G: Add debugging information to the executable file to make GDB work normally; -O0: Set the optimization level to 0 fo

Because the curses program usually occupies a shell for output, it cannot be debugged using the previous GDB method. One solution on the Internet is to redirect the program debugged by GDB to another tty for output. The procedure is as follows: Method 1: First open two tty, GDB filename in tty1, and then tty tty2. At

Label:When debugging with GDB, it relies on the compilation result of g++, because the optimization is used by default at compile time, so it does not execute in code order, but only needs to turn off the g++ compilation optimization.GDB Debug program when the print variable value will appear When using GDB to

In the Linux environment, the compilation language programming is preliminary-use the gdb debugging program-general Linux technology-Linux programming and kernel information. The following is a detailed description. Debugging is an eternal topic in programming, unless your program has never been wrong. This article describes how to use gdb to debug assembler in L

In the past, GDB debugging was used only to debug a single file. During DHCP secondary relay, gdb debugging was required for the entire project. I found that I could not! Now, I am able to share it with you on my blog. The following describes how to debug the isc dhcp code. Start dhcrelay: sudo

include whether the program is in memory and the program's operating level in the CPU, and the GDT that points to is a table with 64 bits in one unit. In this table, you save the code snippet that the program runs and the starting address of the data segment, as well as information about the corresponding segment limit, the page exchange, the program run level, the granularity of the memory, and so on. Once a program has crossed access, the CPU will have the corresponding exception protection,

言是Pascal，那么你可以使用Pascal的语法：x:=4。 在某些时候，很有可能你的变量和GDB中的参数冲突，如： (gdb) whatis width type = double (gdb) p width $4 = 13 (gdb) set width=47 Invalid syntax in expression. 因为，set width是GDB的命令，所以，出现了“Invalid syntax in expression”的设置错误，此时，你可以使用set var命令来告诉

GDB (GNU Debugger) is a powerful command-line debugging tool. You know the power of the command line is that it can form an execution sequence and form a script. The software under UNIX is full of command line, which gives the program development a great convenience, the advantage of the command line software is that they can be very easy to integrate together, using a few simple tools of the command, you c
