you could show the contents (-tree) of a variable in a popover when hovering a variable name in the source window just the same as in the expression window
When I run gdbgui from within a vagrant machine (running Arch), I can access the web UI just fine. I don't get any errors presented and I can tell that it finds the binary, since it doesn't show the "no file specified" error. When I click the "start inferior program from the beginning" button, the status label beneath it is updated to "stopped, exited." However, I cannot fetch any disassembly, set breakpoints, inspect memory, or anything useful. Checking the "automatically break on main" hasn't helped either, as the program just exits.
I'm running the gdb server like so:
# From within the vagrant machine
$ gdbgui -rWhen I run the gdbgui from within my host Arch machine, not the guest Arch vagrant machine, I can load the same binary and fetch the disassembly. Both are using the same versions of all packages.

I am lost as to how to view the source code in the browser and debug it. I went through the screenshots and gif. A small guide of sorts from loading a .cpp file to debugging it would be really helpful.
Hi there,
I wanted to try gdbgui with bash (ubuntu) on windows. I installed gdb, pip and afterwards the gdbgui. I downloaded the hello.c code and used make to compile it.
When trying to run gdb hello I see the output down below. Any ideas what this might be and how I can solve it?
I mostly use lldb on mac and gdb on linux. Could this be made to work with lldb as well?
The mapping in commands from gdb to lldb is 1:1, the commands are often just named slightly differently. I'd like to use something that gives me a smooth experience with both.
When running gdb v 7.6 up to current HEAD, ee7e95efb9 with the mi2 interpreter, and trying to view disassembly in mode 4 (mixed source and disassembly), the line number argument is being ignored. This seems like a bug in gdb that gdbgui cannot do anything about.
for example
-file-exec-and-symbols /home/csmith/git/pygdbmi/pygdbmi/tests/sample_c_app/a.out
-data-disassemble -f /home/csmith/git/pygdbmi/pygdbmi/tests/sample_c_app/hello.c -l 16 -n 1 4\n
^done,asm_insns=[src_and_asm_line={line="16",file="hello.c",fullname="/home/csmith/git/pygdbmi/pygdbmi/tests/sample_c_app/hello.c",line_asm_insn=[{address="0x000000000040057d",func-name="main",offset="0",inst="push %rbp"}]}]
but when I try to look at the next line (17), it outputs the same line (16):
-data-disassemble -f /home/csmith/git/pygdbmi/pygdbmi/tests/sample_c_app/hello.c -l 17 -n 1 4
^done,asm_insns=[src_and_asm_line={line="16",file="hello.c",fullname="/home/csmith/git/pygdbmi/pygdbmi/tests/sample_c_app/hello.c",line_asm_insn=[{address="0x000000000040057d",func-name="main",offset="0",inst="push %rbp"}]}]

Reasons multiple breakpoints may be set with a single click:
http://stackoverflow.com/a/35245024/2893090
This issue was created to document the behavior, and will be fixed in a future version.
.. especially for debug stepping would be so great :3
my program dynamically loads a shared library libhahaha.so
If I set a break point before it is loaded, I see the following
Make breakpoint pending on future shared library load? (y or [n]) [answered N; input not from terminal
and then if I press y, gdbgui would complain that "y" is not a valid command.

This tool looks really good and I am itching to try it out. Wanted to find out if there was a way to install it on a linux server where I dont have admin rights, say for instance within my home directory. Thanks for your help!
I am getting the error:
ReferenceError: invalid assignment left-hand side
when trying gdbgui in Firefox (Seems to work in Chromium) on Fedora.
The error happens at gdbgui.js:2492:8
The code in question looks like:
set_threads: function(threads){
State.get('threads') = $.extend(true, [], threads)
Threads.render()
},where the assignment happens.
I tried on Firefox stable and nightly.
Console is visible in Chrome but not in Firefox 54.

- This pattern provides for a reactive environment, similar to ReactJS
- but with no build system/JSX, but at the cost of less efficiency. I prefer a Vanilla Javascript
- to the complexity ReactJS introduces. ReactJS may be considered if performance becomes an issue
- since it can render more efficently.
This is the comment I found in the gdbgui.js.
Disclaimer: I haven't run this project locally, but the screencast is flickering and I am surprised that you have chosen to reimplement React with jQuery.
What kind of complexity does React introduce in your opinion? Have you considered UMD builds (these are just good old "classic" way of packaging a module into a single .js file with globally exposed interfaces) of ReactJS? You may also like Preact and Inferno projects (they are extremely lightweight ReactJS implementations).
I've thought a long time of building something like this for the Python debugger. I'd love to contribute support for that to this raher than building yet another project that does half of what this one does.
Would you be open to a contribution like this?

An STL container expression, e.g. list1, {1}, with size 1,
after it's updated to {2,3}, with size 2,
the expressions bar only displays the updated 1st element,
but leaves out the 2nd new element.
The current workaround is to use gdb 7.11.1.
The error was first encountered by @sharazam in #52.
The message shown on the frontend is
error Error occured on server when running gdb command: [Errno 32] Broken pipe
when using gdb, pressing up will show previous commands.
gdbgui doesn't keep a history of previous commands.
Method highlight_paused_line_and_scrollto_line is frequently called. Sometimes it's unnecessary, and annoying.
There are some circumstances where the client (user) receives misleading/scary looking messages that are innocuous. For example, when hovering over a variable that does not yet exist red error text is displayed in the console, but shouldn't be.
Add a way to ignore gdb error responses for arbitrary gdb commands.
I feel silly for asking, but is there a way to stop an already running program?
In cmdline gdb, I just do ctrl-c and the program stops wherever it is.
I don't see a similar function in gdbgui.
Hi,
I love this project very much but got a trouble on entering input to my program.
The current gdb command console on the web is working for entering a string to my program but it's not in real-time. Often, I see nothing printed but it's actually waiting for my input. After an input, it would print the messages again. In addition, gdbgui does not support bash color coding, which I think is unnecessary.
Is there any way to redirect/pipe all stdin/stderr/stdout file descriptor to my own terminal so that I can interact with my program on a console instead of the web interface?? Or.... we can enhance gdbgui to simply provide another option which leaves the interaction to the user on the terminal it's been executed instead of taking them away from the console. Maybe using remote gdb can provide this function easily?
The GUI displays ""failed to fetch file at path (some_file).cpp"", where the path exists (I can do ls -l some_file.cpp and get the output).

I suppose highlightjs would be reasonably easy to integrate into this project and would be very beneficial to the user experience.
by default gdbgui should show disassembly if file cannot be fetched (see #60)
gdbgui may slow and exit if the binary file has a large number of source files. Output from the command -file-list-exec-source-files is very verbose, and parser-intensive. It might be a good idea to not run that command if the binary to debug is very large, or just just add a button that refreshes the source file list. The line in question is: https://github.com/cs01/gdbgui/blob/master/gdbgui/static/js/gdbgui.js#L1638
When using a command that changes the current instruction, for example "next", the current line in the UI should change.
This should be the same as pressing the relevant button in the GUI.
Simple suggestion: after each gdb command that is executed get the current line in GDB and if needed update the UI.

First of all, awesome that you made this! I think this could be a great asset when teaching debugging skills of any kind!
Now, for the problem I have:
I'm on windows 7 with pip 9.0.1
Python version is 2.7
And I get this error:
#pip install gdbgui --upgrade
Collecting gdbgui

Complete output from command python setup.py egg_info:

import fcntl
ImportError: No module named fcntl
Any idea why fcntl is failing on me? Is it because this module is only for Unix systems?
This is issue #413 on Flask-SocketIO. When using gevent as the async mode for SocketIO and with debug set to True, it monkey patches the select module and removes, among other things, select.epoll and select.epoll.poll. This results in an unusable app. Again this only applies to gdbgui when the --debug flag is passed.
This issue was created to document the behavior, and will be fixed in a future version. Current workaround if you are developing and running in debug mode is to change async_mode='gevent' to async_mode='eventlet' (and to pip install eventlet).
Hello @cs01
Thanks cool debugger!
I get following error when I try to look vector's inside.
My environment is as below.
| OS | Web browser |
|---|---|
| Ubuntu 16.04 | Firefox |
When I debug following program for now.
#include <iostream>
#include <vector>
using namespace std;
int main(void)
{
vector<char> str;
vector<double> pos(3);
vector<char> a(10,'a');
vector<double> d {1.1, 2.2, 3.3, 4.4};
vector<double> cop(d);
for(auto itr = begin(d); itr != end(d); ++itr)
{
cout << *itr << "\t";
*itr += 10;
}
cout << endl;
for(auto itr = begin(d); itr != end(d); ++itr)
{
cout << *itr << "\t";
}
cout << endl;
return 0;
}Then I compiled and run following command to launch gdbgui
$ g++ -std=c++11 vector.cpp
$ gdbgui ./a.out
And tried to d vector's inside. But I got error.
Could you tell me what I make a mistake?
Thanks in advance.
It's probably better designed (though not as battle-tested).
See https://github.com/o11c/ungdb/blob/master/gdbmi/__init__.py
When I call gdbgui in terminal, error is throwing and nothing more happenes.

It would be useful to be able to specify working directory and inject LD_LIBRARY_PATH / LD_PRELOAD to debug more complex frameworks.
Can you help with exact steps for disassembling binaries using gdb-gui?
I'm trying to use this program, but I get the following error in the GUI:
Unable to find Mach task port for process-id 19311: (os/kern) failure (0x5).\n (please check gdb is codesigned - see taskgated(8))
I'm on OSX 10.11 and installed gdb through homebrew
I installed gdbgui but as soon as I try to run it, it opens up a window in the browser and then immediately crashes followed by a traceback that is printed saying that it "cannot import name 'POINTER'" (screenshot attached). Is there something I'm doing wrong? Any help would be appreciated, thank you
More of a request than an actual issue, but I have a use case where I have a Go binary compiled using gccgo, and use the command line GDB to debug it. I cannot use your tool to debug it due to the non-commercial aspect of the license.
Will you consider modifying the license to one that will allow the use of this tool in commercial settings?
The following steps result in gdb hanging and not returning a response:
dA simplified version of this occurs with the following mi commands:
-file-exec-and-symbols /home/csmith/git/gdbgui/examples/cpp.a
-break-insert main
-exec-run
-enable-pretty-printing
-var-create - * "d"
-var-list-children --all-values "var1"
Note that gdb does not hang with the following script (pretty printing not enabled):
-file-exec-and-symbols /home/csmith/git/gdbgui/examples/cpp.a
-break-insert main
-exec-run
-var-create - * "d"
-var-list-children --all-values "var1"
gdb mi supports remote debugging, i.e. -target-select. Add a UI element to choose remote target.
with gdb, if I press control + c, I can stop the current process,
with gdbgui, there is no pause button.
there is an int button, which I thought was a pause button, but it doesn't seem to be the case.
