I have just installed codelite in my windows 8.1.It shows error
Debugger exited with the following error string:
"No executable
specified,use 'target exec'"
I searched and found this (another stackoverflow question) I did the same as mentioned there but nothing really worked for me.I made a new project and selected Simple executable (g++) and GNU debugger as default debugger.Can anybody help me with this.Also it shows "Program exited with return code: 4199040".
It seems that you don't provide executable to run/debug:
Go to
Project settings... -> Common settings -> General
and fill correct information for
Executable to Run / Debug
Jarod42 provided a 'close enough' answer. On Linux the steps seem to be:
Workspace -> Open Active Project Settings... -> General
and fill correct information for
Executable to Run / Debug
In the command prompt:
gdb (program type: example python or c or c++ etc)
If am running python program then the command will be gdb python
then (gdb) run program_name.py

I'm trying out STM32CubeIDE, and I've been trying to get it to work with the GDB QEMU debugging plugin that's part of the Eclipse CDT package. I've been able to create the project and debug configuration for my STM32F4-Discovery board, and the debugger partially launches, however, just as the simulator starts up, the GUI window it creates suddenly crashes and I get this error:
Error in final launch sequence
Failed to execute MI command:
-target-select remote localhost:1234
Error message from debugger back end:
Truncated register 18 in remote 'g' packet
Failed to execute MI command:
-target-select remote localhost:1234
Error message from debugger back end:
Truncated register 18 in remote 'g' packet
Truncated register 18 in remote 'g' packet
I think this is caused by some mismatch between the CDT plugin I installed and the GCC toolchain that shipped with my installation of Ubuntu 20.04. However, I'm not sure how to fix this.
Is there anything I try to fix this?
So it looks like there were a couple factors as to why this wasn't working. First off, the error messages that I was getting immediately after the GUI debugger terminated were due to an incorrect installation of the arm-none-eabi-gdb package. In order to fix this, I downloaded the package from the ARM site and followed the instructions detailed here. After installing the arm-none-eabi-gdb package again, I went into the project debug configuration settings, navigated to the "debugger" tab in this window, and then changed the GDB executable path from the variables the IDE had set for me to the actual GDB executable path (in this case /usr/bin/arm-none-eabi-gdb).
After that was done, the debugger would no longer immediately terminate, but I was still getting some errors in console shortly after it started (see below). In addition, the debugger GUI would produce no meaningful output, and Ubuntu would warn that the process had frozen.
NVIC: Bad read offset 0xd88
qemu-system-gnuarmeclipse: Attempt to set CP10/11 in SCB->CPACR, but FP is not supported yet.
To solve this, I right clicked the project in the project explorer panel of the IDE, then went to C/C++ build section, then to the Settings section under that, and then finally to the "Tool settings" section of this menu. Under "MCU settings", there are two options for "Floating point unit" and "Floating point ABI", which I changed to "None" and "Software implementation" respectively. After saving these configuration changes, I went to the system_stm32f4xx.c file under the src/ directory of the project, and commented out these lines:
/* FPU settings ------------------------------------------------------------*/
#if (__FPU_PRESENT == 1) && (__FPU_USED == 1)
SCB->CPACR |= ((3UL << 10*2)|(3UL << 11*2)); /* set CP10 and CP11 Full Access */
#endif
After that, I cleaned the project, rebuilt it, and relaunched the debugger. It then functioned normally.
I am trying to put the gdb to run with eclipse cdt on ubuntu to start debugging some simple programs. So I did the steps I reckon as necessary to get it running:
1. Create an executable project
2. Compile
3. Run
4. Create the file .gdbinit and place it on the main project folder
5. Set some of the debugger configuration:
5. I also tried to find a .gdbinit file that would look some like this:
set schedule-multiple
dir ~/gcc_build/4.7.2/build/gcc
dir ~/gcc_build/4.7.2/gcc
dir ~/gcc_build/4.7.2/gcc/cp
dir ~/gcc_build/4.7.2/gcc/lto
source ~/gcc_build/4.7.2/build/gcc/gdbinit.in
But I didn't find anything similar in my computer, even after doing a:
# find / -name .gdbinit
So, my file .gdbinit end up with the simple content - yes only that:
set new-console on
Then I clicked on Apply and Debug:
The gdb starts working nicely as expected. I press the button "step over / F6" and the debugger goes jumping through the code step by step. Until the point it reaches the command rand() and the gdb hangs with the message:
Can't find a source file at "/build/buildd/eglibc-2.19/stdlib/rand.c"
Locate the file or edit the source lookup path to include its location.
Thus I also tried unsuccessfully to find the rand.c to update this path to include its location:
# find / -name rand.c
# find / -name stdlib
After the error message from GDB complaining that rand.c is missing, then I tried to keep stepping... since then the stepping mode is disable when I restart the debug:
Is this problem happening because some setting for my file .gdbinit is missing? Or some how GDB is not able to find the rand.c from stdlib from c99? When I compile and run the program it runs nicely. Only when I try to launch the debugger is when GDB crashes.
Update: I got the missing rand.c problem after running the commands:
# apt-get install libc6-dbg
# apt-get source libc6
But now a different error appears:
Can't find a source file at "/build/buildd/eglibc-2.19/csu/libc-start.c"
Locate the file or edit the source lookup path to include its location.
Should I also install that library for gdb?
All suggestions are highly appreciated.
From what I saw on your description... looking to the 4th and 5th image you posted, you did right all the required steps.
However, it seems to me that your GDB is attached to several projects. That means that unless you really need that, I would strongly advise you to select all project that you are not currently debugging and delete them from the debugger mode. So, my suggestion is that after you have done all the steps you did so far, then go on:
Debug Configurations > C/C++ Applications: (drop down it)
... then click on each project you are not compiling, with right button from the mouse select "delete" - but don't worry, it will not delete your project, but only the attachment of that project to your debugger mode.
Then restart the eclipse. When you again try to run in the debugger mode, everything will run much smoother than before.
Step1:
Go to https://www.gnu.org/software/libc/ to download glibc.
Step2:
unzip it locally and whenever the eclipse prompts "Can't find ... xxx.c", just load the file into eclipse. It will work.
I am trying to get eclipse set up to work with C++, however when I try to run a basic program I get the error: Launch failed. Binary not found
Also this prints to the console:
Configuration failed with error
(Cannot run program "sh": Launching failed)
This is the path that I have set:
C:\Program Files\Java\jdk1.7.0_01\bin;C:\msys\1.0\bin;C:\mingw\bin;
All help will be appreciated.
For Windows:
Project / Properties / C/C++ Build / Settings /Binary parsers:
Turn on "PE Windows Parser"
Then, build it (Ctrl+B) before running/debugging

I'm using Xming to connect to a Linux (enterprise edition) server on which I'm trying to debug a C++ project in Eclipse Galileo. The following errors occurred:
Reading symbols from ../workspace/myfile ..(no debugging symbols found) ... done.
.gdbinit : No such file or directory
Setting environment variable "LS_COLORS " to null value
(.gdbinit is on the server (in root), my account has rights)
If i try to run gmake on the same file from the terminal I get the following error :
gmake ** No rule to make target /workspace/myfile' . Stop.
//I have exported the path (including the library path), and gmake exists.
My project has 3 subprojects (proj1 , proj2 and proj 3). In order to debug proj3 I have to build projs 1 and 2 . I created make targets for projects 1 and 2, and I obtained .so files for which i made softlinks to corresponding files in my_project/libs folder.
My Eclipse debug configuration is as follows (tab order):
Main
Project: My Project
Build Configuration: UseActive
C++ Application: path to my project/myproject
Environment: path to libs on server (my user rights)
Debugger
Debugger: gdb/mi
(Checked) Stop startup at main
GDB debugger: gdb
GDB command line .gdbinit
GDB command set: standard
Protocol mi
Project Properties:
Builders CDT Builder
Scanner Configuration Builder

Behaviour
build incremental build : all ( sometimes i get the error no rule for make all)
Clean: clean
Discovery options:
(Checked) Automatic discovery path
(checked) Report path detection problems
Discovery profile GCC per project
(checked ) Enable build output
Compile invocation comand gcc
Toolchain
No toolchain
Correct builder GNU make builder
This Eclipse debug configuration works on another account (on the same server using the same Eclipse). The gdbinit and gmake files are on the server and work, I'm not supposed to update the versions (this was one solution I found online).
Has anyone seen this error before? Does anyone have a clue what I'm doing wrong?
I'd like to debug to debug a remote application with GDB.
My target system is a FreeBSD 8.3 box with gdbserver running. The application has been compiled successfully on that box. My Eclipse CDT 4.2 runs on Windows 7 with recent MinGW installed.
This is an external program I'd like to debug. It is neither written by me nor I do have it as a library. I do not intend to write my own program. In this case it is Subversion 1.8.0-dev which I want to debug.
I have created a simple C project, attached the source of Subversion. Created a remote debug config and attached the sources to the running thread in gdbserver.
Now, eclipse enters the main function of Subversion but when I set a breakpoint in another attached source file, Eclipse says: No source file named ra_loader.c or it simply says "No source available".
Then It simply exists the application.
What am I missing here?
Try the suggestion made on this thread
Quote :
1) run a debug session and open the gdb console inside Eclipse
('Console' tab -> 'Display Selected Console' button -> choose the one
ending with 'gdb')
2) use command 'pwd' in the console to print
gdb's current working dir
3) use command 'info line main' to get
the source file where gdb expect to find of my "int main(...)"
function
4) concatenate the result of step 2 with result of step
3 (which should be a relative path) to see if it matches the
correct source file I want
5) use the 'cd' command in gdb (to
change the current working dir) till I get the correct match in
step 4
Knowing the initial working directory (2) and the correct working directory (5) for gdb , I had 2 options: 1) Use gdb's 'cd'
command every time I launch a debug session (I could setup a
.gdbinit file in the gdb initial working directory to do this
automatically) or 2) Setup the 'Source' tab, in 'Debug
Configurations', to make Eclipse use paths that match with gdb's
initial working dir ('Project - Path Relative to Source Folders'
worked for me)
