On Linux, I have some C++ programs built with my own makefiles, and I'm looking for some GUI debuggers to debug them at source level.
Previously I use KDbg(2.5.2) on openSUSE(12.3). It works but with some very annoying limitation, e.g., I cannot set a breakpoint when the debugged program is not trapped by Kdbg -- I mean, in order to set a new breakpoint, I have to set it before the program is launched or the program pauses on hitting an already set breakpoint.
Now I try to use Eclipse CDT. I got eclipse-cpp-juno-SR2-linux-gtk.tar.gz but find that I don't know how to load my executable so to start debugging.
I googled with words like 『eclipse debug pre-built C binary』, but few seems to care about this feature.
Can Eclipse CDT really do that? If Eclipse CDT can't, is there any better alternatives to KDbg? Please help.
According to hint from this answer, https://stackoverflow.com/a/248119/151453 , I finally figure out how to do it.
The key point is: In the Eclipse CDT project, create/edit a Launch Configuration so to tell the debugger what executable to load.
Now I have to admit, Eclipse CDT does quite well in C++ code debugging far better than KDbg.
Some screen shot below, on openSUSE 12.3 .
Now we can Run -> Debug (F11)
Debugger automatically pauses the program at main()'s first statement.
The Stand-alone Debugger is an Eclipse application which packages the Eclipse plug-ins from the CDT (C/C++ Development Tools) project into an application that can be started from a command-line script:
bash /path/scripts/cdtdebug.sh -e executable [args]

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.
I have a simple mixed C/C++ application (OpenGL example) which I have successfully built using Eclipse CDT in Juno (MinGW toolchain).
I can run this application fine by hand from a Win7 command console, but it seems to rarely work when running from Eclipse's "Run as" menu. Whether it works or not seems down to seemingly unrelated changes in the code, and I get nothing of interest on the Eclipse run console (just a <terminated> status) even when no code near the start of the application has changed.
I'd like to and it sometimes I can work around this for now, but would be good to get this working if anyone has any ideas - it seems an essential stepping stone to get the debug environment working in Eclipse.
EDIT Side thought - eclipse seems awfully thin on debug diagnostics when something like this fails. If there is any way to turn on more debug I'd welcome the knowledge =)
Resolved - the issue is down to the path being given to the application, or more specifically the OS launcher (so it can find the DLLs it needs).
Even through the default "run" config claims to inherit the parent environment, it doesn't seem to get the same environment as the Win7 command console. I had to manually edit the "Run as" config in Eclipse to have a custom PATH environment variable containing the directories I needed (MinGW/bin, and a directory containing some custom DLLs).

I am using Eclipse Juno with MinGW (latest version) on my Win7-Laptop.
My example code is successfully built within the IDE, but I can neither run nor debug it!
When I choose Run as=>Local C/C++-Application, I get
Launch failed. Binary not found.
However, there IS an exe-file as a result of the build process!
When I call cmd.exe, navigate to the source directory and call this built exe (a.out.exe), it works without problems!
I guess this is due to wrong/missing configuration of eclipse, but I couldn't find useful info on that so far.
This thread mentions environment variables. I added MinGW and Msys to my PATH variable (that's why I can compile) but I can't run my software in eclipse!
So, what can be done to enable debugging?
I have made a little tutorial.
how to set all for Eclipse have a look it's here https://stackoverflow.com/a/12169583/1322642
Hope it can help you a little bit.
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
I am using eclipse cdt to develop a c++ program. One thing that drives me crazy is that either eclipse cdt or gdb which it uses for debugging break automatically on main method entry. I don't want to break there!
Before I had some problems and had to recreate my project from scratch, I managed to disable this feature (I think) but for the life of me I cannot find it now! Problems seems to be the eight million different places where debug settings can be found in eclipse.
Does anyone know how to disable this?
Go to Run / Debug Configurations / Debugger / Stop on startup at: [main]
