Version 2
Image

A simple gui implementation for gdb just for the freebasic programming language.
Linux , Windows

Tested with GDB 8.1.0.
Tested a bit with GDB 10, GDB 11

1 version is very simple (toy)
2 version is a fully functional program

Video clip for version 1 : https://disk.yandex.ru/i/vMZIc9tHPssB2Q

Download

GDB debugger for windows 64-bit can be downloaded from here. Build from source codes myself.

Updated. Now works same on the platform Windows 64-bit

If there are problems with finding a debugger under Windows 64-bit, then in the first post of the topic there is a link to download GDB 64-bit

upd:
I forgot to write. If someone is going to build the program from source, update window9 for windows.

Hi All

Tried to compile in Debian and got the following:
  • FreeBASIC Compiler - Version 1.07.1 (2019-09-27), built for linux-x86 (32bit)
    Copyright (C) 2004-2019 The FreeBASIC development team.
    target: linux-x86, 486, 32bit
    compiling: Debug.bas -o Debug.asm (main module)
    /home/dinosaur/FBDebug/declares.bi(1) error 23: File not found, "window9.bi" in '#include Once "window9.bi"'
Is Window9.bi needed for Linux and if so, it is not included with FB
Is it compatible with 32 bit Linux ?

Regards

Windows9 is the graphical user interface library it uses. According to this page, Windows9 should build on Linux.

The program is only supported on 64-bit platforms. This is indicated in the first post in blue.

Updated. Now the program should also work on windows-32bit, linux-32bit. The first post has been updated. The archive has been updated. Now in the archive:

1) source files
2) LIB folder: (DLL files for windows; * so files for Linux). For Linux 32-bit, the latest version of Scintilla is compiled on Debian 11.1.
3) BIN folder: (EXE files for windows; executable files without extension for Linux).
---- EXE building: windows 7 32-bit , windows 10 64-bit , linux mint 19 x86-64 , linux debian 11.1 (32-bit)

Hi All

Linux Debian 10.11 32 bit

Got as far as:
ld: cannot find -lwebkitgtk-1.0
Trying to install libwebkitgtk-1.0
Note, selecting 'libwebkitgtk-1.0-0' for regex 'libwebkitgtk-1.0'
After install doing a search for libwebkitgtk gets no hits of anything with libwebkitgtk in the name.

No install candidates for libwebkitgtk-1.0-dev or libwebkitgtk-1.0.0-dev.
The only candidates for installing on Debian are libwebkit2gtk-4.0-dev

What am I missing here ?

For debian 10 you need to manually download and install the packages in order of priority:

1) libhunspell-1.4-0: https://packages.debian.org/stretch/libhunspell-1.4-0
2) libenchant1c2a : https://packages.debian.org/stretch/libenchant1c2a
3) libicu57: https://packages.debian.org/stretch/libicu57
4) libjavascriptcoregtk-1.0-0: https://packages.debian.org/stretch/lib ... egtk-1.0-0
5) libwebkitgtk-1.0-0: https://packages.debian.org/stretch/libwebkitgtk-1.0-0

Image

Debian packages are installed using the dpkg command, for example:
sudo dpkg -i libenchant1c2a_1.6.0-11.1+b1_i386.deb
After installation in the folder /usr/lib/i386-linux-gnu/ the file will be located: libwebkitgtk-1.0.so.0.22.17
Go to folder /usr/lib/i386-linux-gnu/ and create a symlink:
sudo ln -s libwebkitgtk-1.0.so.0.22.17 libwebkitgtk-1.0.so

Hi All

Vanya many thanks for the instructions.

However lots of undefined references

Hi Dinosaur!

Different versions of GDB display slightly different information. Debian 10 has gdb 8.2 and its output differs from 8.1, 10.1, 11.1. At the moment I have updated the archive, please download a new one.
By the way, please tell me you also have GDB 8.2?
However lots of undefined references
compilation should be something like this:

fbc Debug.bas debug_gui.bas dialogs.bas pipe.bas interface.bas

Hi All

Vanya, I am so used to making projects in Geany that have one Project.bi which has all the includes, that I never
looked beyond my nose to see that others don't.

Anyway it all compiles without a problem and my GDB is:
GNU gdb (Debian 8.2.1-2+b3) 8.2.1

Code: Select all

(Debug:1978): Gtk-ERROR **: 19:12:07.970: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
Trace/breakpoint trap
I changed Window9.bi uncomment :#define __USE_GTK3__ BUT that didn't make any difference.

Running your included binary file works correctly and solved a problem that the previous version had, which was:
A multi module project didn't show the main module in the debug window, so you could not set a BP at the start.

Worth noting that I have used "Gede" debugger for a couple of years now, but it has annoying problems and I am hoping that your front end doesn't.
How do you change the colour of the high lighting bar ? so it is more pronounced when stepping ?

You are mixing GTK2 and GTK3. The program is made with GTK2 in mind. I think you took the file libwindow9.a from folder bin/lin32/gtk3 - it is not right. You need to take the file libwindow9.a from folder bin/lin32/gtk2
I changed Window9.bi uncomment :#define __USE_GTK3__ BUT that didn't make any difference.
You don't need to do this for GTK2.
How do you change the colour of the high lighting bar ? so it is more pronounced when stepping ?
The program uses the default highlight color. If you like, you can add color change lines in sci.bi in the SetOptionsciHWND procedure after the line:

Code: Select all

SendMessage(sciHWND,SCI_INDICSETSTYLE , 0, INDIC_FULLBOX)
paste:

Code: Select all

SendMessage(sciHWND,SCI_INDICSETFORE , 0, &hff0000) ' color blue for example
SendMessage(sciHWND,SCI_INDICSETALPHA , 0, 10) ' alpha 10 , can be done (from 0 to 255)
P.S. The program can be compiled taking into account GTK3, but then you will have to rebuild Scintilla yourself with settings for GTK3

Hi All

Vanya, I can now compile & run without any issues.
The colour selection is great.

Will now test on projects and let you know how I go.

One final question:
Type MyType
Value as integer
End Type
How do we see the value of MyType.Value ?

Regards

EDIT: In fact I am not seeing any values.
Correction: When pressing update the standard Integers show values.

Hi ALL!

Released version 2 of the program. The first version is also available for download.

What's new in the second version:

1) found bugs fixed
2) the interface was changed (icons appeared instead of labels, a pop-up menu was added)
3) it became possible to change the value of variables (a menu is called in the variables window)
4) you can copy data from the variables window (the menu is called in the variables window)
5) you can enable / disable auto-update of variables during step-by-step debugging (the menu is called when you press the OPTIONS button)
6) the output of global variables is optimized

Unfortunately, on 32-bit systems there is an unsolvable problem with updating global variables (voiced here). This is a problem with variable and struct names that GDB does not recognize. Due to this problem, the data of variables in the GUI may be incorrect.
