1) is there a way to run gdbgui on my main PC (using a pi for development)
2) when I hit load binary pointing it to my code, it says no such file or directory exists, do I have to use the commandline at the bottom to load it?
3) is there a way in the expression section to get the address of a label?
Hi @Watergard let me see if I can help
1) Yes. See https://www.gdbgui.com/guides/. You can either run gdbgui on the pi, or run gdbserver on the pi
2) You don't have to use the command line at the bottom to load a binary. If the binary exists on the machine the gdbgui server is running on, it should work. (The binary is the compiled output of the code, not the source file)
3) I am not sure what a label is, but if you are programming in C, you can do something like &myVariable and it should give you the address.
Hi guys.. Trying gdbgui for the first.. Had a question about attaching to process... So, the way I used to do this before was:
Run my program: ~./myprogram
Attach to process: gdbtui -p <pid>
Set breakpoints "b <func>", followed by "c" to continue.
Then, I trigger something on my running program, which hits the breakpoint in gdbtui...
With gdbgui, I am not able to find "attach to process" option.
When I try running like this: gdbgui "~/.myprogram", I am unable to connect to my program to do any triggers. How do should I do this?
@Primalr3d it should be turned on by default as long as you have python support built into your gdb binary. To test this, run
gdb --interpreter=mi2Then in gdb, run
-list-featuresto see if Python support is on.
There is also a setting in the gdbgui settings menu to turn pretty printing on/off. Click the gear icon in to the top right.
tab key sends the complete command to the prompt

groxx I realize this isn't (probably?) a general gdb room, but would anyone know if there's a way to do rr-like recording in gdb? I know I can record execution of a binary, but I'm dealing with stripped binaries and it stops every 1-10 instructions, so it'd take me years to c enough to reach the execution points I'm interested in.or maybe an alternative Q: is there a way to tell gdb to continue execution even when it encounters an error?
