(These instructions are for mingw32, not the mingw-w64 fork. You can get the latest mingw installer here which can in turn install gdb.Īfter installing MinGW, run the "MinGW Installation Manager" (which for me was located in C:\MinGW\libexec\mingw-get\guimain.exe ) and then make sure that the mingw32-gdb bin package is installed.
HOW TO INSTALL GDB ON BASH WINDOWS
MinGW distributes a Windows version of gdb. If you are using Linux, you probably already have gdb, but if you are using Windows, you will need to install it. When used together with gdb, it can provide useful information about crashes. The latest debug build of the OHRRPGCE is available here: ohrrpgce-wip-directx-sdl-debug.zip. 1 getting a debug build of the OHRRPGCE.Still the gdbserver will not exit in the target machine, so you can change the ‘remote exec-file’ at any time, and debug a different set of program. Now either you can ‘continue’ or ‘detach’ the program from debugging. Note: In the above case, the executable “my_prg” is present under “/” on both target and host. ‘run’ is used to run the program, which stops at the breakpoint main().‘b main’ is used to set breakpoint at main() function.‘file /my_prg’ is used to load the debugging symbols from the program in the host.‘set remote exec-file /my_prg’ is used to set the program which you want to debug in the target.‘target extended-remote’ is used to run gdbserver in multi process mode.
HOW TO INSTALL GDB ON BASH PC
Note: breakpoint 1 also set at pc 0x400550.
Reading symbols from /my_prg.(no debugging symbols found).done. On Target, run the gdbserver with –multi and without a program name. In real-time, you may want to debug multiple programs remotely, and you may not want to start the gdbserver every time with different program names. In the previous demo, you would have noticed that once the program executed successfully, the gdbserver also got exited. Now the gdb will suspend the process 3850 in the target and you can debug the program using normal gdb commands. Attach gdb to a Running Process on Targetįirst you have to find the process ID of the running process in target. On Target: Remote debugging from host 192.168.1.20 If we continue our program, the output of the program will be printed in the target machine.
In the last example, we have put a breakpoint in main() function. Now we have connected the gdb for remote debugging. On Target Machine, $ gdbserver localhost:2000 my_prg The following C program example will be used to demonstrate the remote debugging.
Now you can run the normal gdb commands, as if you are debugging a local gdb program. Use “target remote” to connect to the target system. You can also load the symbols separately in the host using “file” command in gdb. The executable file and the libraries in the host, must exactly match the executable file and libraries on the target, with an exception that the target binary symbols can be stripped. The above command suspend the execution on my_prg, and waits for a debugger to connect to it on port 2000. So you can strip symbols out of your program binary to save space. gdbserver doesn’t need the symbols from your program to debug. gdbserver then automatically suspends the execution of your program at its entry point, and it waits for a debugger to connect to it. To do remote debugging, start your program using the gdbserver. You need to have the “gdbserver” executable on the target machine. Target machine is the one which is running the program which you have to debug.
