How can I enable breakpoints in Eclipse/CDT - gdb

I'm using Eclipse 3.5.1 on Ubuntu 9.10, with CDT 1.0.0.200909110608
If I right-click the left margin for a context menu, Toggle Breakpoint, Enable Breakpoint and Breakpoint Properties are all grayed-out.
How can I enable these?
Apart from breakpoints, the debugger and the rest of CDT are working fine.

Check Run->Breakpoint Types->C/C++ Breakpoints

Turn off "Skip all Breakpoints". That worked for me.

Unable to create a debugging engine in QT editor

I have recently installed Qt Creator 4.8.0 based on Qt 5.12.0 and I have it configured like in the image below. However, I haven't managed to start the debugger. As it can be seen, the debugger is correctly set for this kit, the one I'm using right now.
Any solution?
Thanks!
Wow! I found it!!! Here in the tab "projects", there are several build and run configurations. Despite you select a default kit, the final one being executed is the one in black under this tab.
Finally I disabled all of them except the one that was properly configured in the Kits window and it worked. I hope this information is helpful for someone. I don't think that part of the configuration is clear.
I got the same error, but in my case I was using the MSVC compiler and the kit didn't manage to find the CDB debugger. I was able to fix it by going to "Add or remove programs" -> "Windows Software Development Kit" -> Modify -> Change -> Debugging Tools for Windows.
In my case it was needed to select "Enable C++" under Debugger settings

The same dumm error QT creator shows when you simply don't have gdb installed.
Worked in my case ;)
I had the same error in MacOS, debugger suddenly stopped working (LLDB debugger worked in XCode but not Qt Creator).
In this case, I reinstalled Qt Creator and reinitialized the config by removing the .config/QtProject directory located in homedir. This solved the problem.
I had the same issue when Qt Creator didn't recognized the path to the Debugger. Due to some reason it showed multiple Auto-detected Debuggers at the same location. And on the top one of the list with the red error indicator.
see
Projects->Manage Kits...->Debuggers
I removed the erroneous Debugger and restart the Qt Creator.

How to disable/delete all breakpoint in Qt Creator

Is there a way to disable all breakpoints in Qt Creator?
If there is not, Is there a way to delete all breakpoints?
My Qt version is 4.7 and my OS is Ubuntu 12.04.
Go to the debugger pane at the bottom of the IDE. In the bottom right corner, there will be a breakpoint tab. Click this and you should see all breakpoints displayed. Now you can CTRL + A and right click and delete all breakpoints.

Breakpoints do not work on CDT 8.4.0 for Eclipse Luna for Linux

I had good times debugging Java applications on Eclipse, but recently that I'm working on a C/C++ on Ubuntu 12.04 using Eclipse CDT, it ignores the breakpoints when debugging! I've tried two versions of Eclipse CDT, CDT 8.4.0 for Eclipse Luna, but doesn't work either. Can somebody help with that?
NOTE: I know there are some other similar questions, but I was thinking it is better to ask this question which specifically addresses CDT 8.4.0 for Eclipse Luna.
The eclipse-cdt is shipped only with the required tools for building c/c++ applications. It does not ship with gdb. You need to install that separately
How do I use GDB in Eclipse for C/C++ Debugging?
From link above these are the steps to follow.
1. Go to Help > Install New Software.
2. Add the CDT repository http://download.eclipse.org/tools/cdt/releases/8.4 to the list of repositories.
3. Select the CDT Repository. Now you need to install the CDT plugin along with GDB support from the list of available plugins (Select the CDT Main Features as well as CDT GNU Toolchain Debug support).
I updated the CDT repository path to correspond to your release (Luna).
It also happens for me in ReadHat 64
Seems like if the CDT breakpoints are not suitable for the current debug session, in the breakpoint window, when enabling "Show breakpoints Supported by selected target" all my breakpoints disapears from the list.
In my case, my ELF have debug info and all the breakpoints that I place are in the main ELF.
My debug settings worked fine with the former Eclipse version.
I rolled back to eclipse Juno, and my debug session with same elfs worked out of the box.
Experiencing the same problem here.. I am working around it by manually setting breakpoints after starting debug session. Console -> gdb, then type "break xxxx".
If you're using MinGW gdb, check that C:\MinGW\bin is in your path (set in System Properties). Made all the difference for me.
I once had Skip All Breakpoints accidentally checked, and was wondering what was going on.
I have the same problem with my eclipse Photon, I figured it out by unchecking the
"stop on startup at: main" in Debug Configuration-->Debugger.
I know this in Rikard Söderström's response to you.

Stepping through a program using Eclipse IDE

How do I step through the program one line at time.
Also, how do I view the console input?
I recently installed Eclipse IDE here:
http://www.eclipse.org/downloads/
Eclipse IDE for C/C++ Developers (includes Incubating components)
Go to Run, Debug Configurations and click the Debugger tab.
Make sure that there is a gdb debugger selected. If not click Browse find the gdb.exe. It will probably be in your installation directory (of eclipse I mean under the /bin subdir).
Hope it helped. :D

Stop eclipse CDT from debugging from main()?

If I debug my C++ code using eclipse CDT, it appears that it always starts the debugging process from the main() function, even though there is no breakpoint at the beginning of the main().
Is there a way to have eclipse CDT start to debug from the first breakpoint rather than main()?
On the menu Run -> Debug Configurations, right click the C/C++ Applications item on the left, and create New configuration. Go to the Debugger tab and uncheck the Stop on startup at checkbox.
Open "Debug Configurations" GUI
Choose your application
Select "Debugger" tab
Uncheck "Stop on startup at main"
