Java Forum / General / May 2006newbie question about eclipse perspective...
Hi, I just downloaded eclipse with the CDT (c/c++ extension) and now I can compile programs using makefiles. That's great... But when I debug I guess it calls the gdb-debugger and when it returns it keeps bringing me a dialog box which says: "Confirm Perspective Switch" in the heading and "! This kind of launch is configured to open the C/C++ perspective when it suspends. Do you want to open this perspective now?" Ofcourse I could just answer "no" and "remember this setting", but where is this set up in the program?

Probably somewhere in Windows->Preferences. I don't have the CDT plugin, so I can't give you an exact location, but when you open Windows->Preference, you'll see a textbox with the contents "type filter text". Type in something there like "CDT" or "C/C++" and you'll only see the preferences related to CDT, which will narrow down your search. - Oliver >> Hi, >> [quoted text clipped - 15 lines] > text".

I found it, but I still have a problem. Perhaps you can see it too under Windows -> Preferences -> Run/Debug -> Option 3 or 4 from the top. It says: "Activate the debug view when a breakpoint is hit". I have that box marked... Below it says: "Open the associated perspective when an application suspends". And here it is (I found out by experimenting)... I had it on "prompt" before. If I put it on never, it doesn't asks me again. But actually I would like to have it on "Always" if I could just change the associated perspective to "Debug"... I even tried to do that under General -> Perspectives -> "Debug" is now default... But it still doesn't work. Somehow C/C++ is associated. I tried to close all perspectives and start them again... Yet I get: "!This kind of launch is configured to open the C/C++ perspective when it suspends. Do you want to open this perspective now?" Anyone knows how to do it - make "Debug" the associated perspective?

I suspect you cannot do that. Your best bet would be to write to the developers of CDT asking for them to add in this option. Get an account on Eclipse's newsserver (see http://www.eclipse.org/newsgroups/), then post to eclipse.tools.cdt. - Oliver Are you able to manually switch the perspective to debug with Window/Open Perspective/Other.../Debug? > Are you able to manually switch the perspective to debug with > Window/Open Perspective/Other.../Debug? If you want to debug perspective then right click on your program and the select "Debug as..." The Debug perspective automatically opens. It should stay opened and you just have to click on the perspective tab or what other perspective you have open at the same time in the Tabs to move back and forth. SignatureThanks in Advance...

The debug perspective will only open when you select "Debug As..." if you said "Yes" to the first time when Eclipse asked "Do you always want to switch to the debug perspective when debugging?" and checked the "Never ask me again" box. If you said "No", then the way to access the debugging perspective is to use the menu "Window->Open Perspective->Other..." then in the list, select the Debug perspective. - Oliver >>> Are you able to manually switch the perspective to debug with >>> Window/Open Perspective/Other.../Debug? >> >> If you want to debug perspective then right click on your program and >> the select "Debug as..." The Debug perspective automatically opens. What exactly do you mean by "right-clicking the program"? I can't right-click and select debug as anywhere, I think. >> It should stay opened and you just have to click on the perspective >> tab or what other perspective you have open at the same time in the >> Tabs to move back and forth. It stays open and doesn't bug me if I disabled the "suspend prompt". This "suspend prompt" is apparently enabled by default. But my problem isn't big - I can just disable it. > The debug perspective will only open when you select "Debug As..." if > you said "Yes" to the first time when Eclipse asked "Do you always want > to switch to the debug perspective when debugging?" and checked the > "Never ask me again" box. I can't remember if it asked this. > If you said "No", then the way to access the debugging perspective is > to use the menu "Window->Open Perspective->Other..." then in the list, > select the Debug perspective. I usually just click on the "Debug"-perspective in the top right corner next to where the C/C++-icon is, but that should be the same - at least the result is.

I just remembered you're working with C++ and not Java. Perhaps the CDT doesn't use the debugging perspective to do its debugging. Recall how, when you tried to do some debugging, it tried to convince you to switch to some other perspective. Have you tried going to that perspective that it suggested, and seeing if the debugging information shows up there? Alternatively, just go to the Eclipse CDT newsgroup and ask them about it. - Oliver -snip- > I just remembered you're working with C++ and not Java.

Nothing. > Alternatively, just go to the Eclipse CDT newsgroup and ask them > about it. Huh? I'll do that. But I don't think I have it on my news-server because if I search for eclipse I only get some astronautic cosmic group. I also tried to search on google groups for "eclipse cdt plugin" but didn't really find anything useful. What's the name of the eclipse newsgroup? I hope I can access it on google, although I've never tried writing with google groups.

You have to make sure that the binary actually contains debugging information and the information is of the correct type. For GNU compilers you have to add the -ggdb3 flag to the compile and link. You don't usually want this debug information in the version you ship so you either need to have a different profile that doesn't generate this information. You can also run a strip program to strip the information, but you usually want to change optimization as well between debugging and the shipping version. If you are running the program remotely and connecting with GDB on the target then you can run your program with the symbols stripped on the target, but use the one with symbols on the machine running gdb. Another issue affecting debugging is the finding of source files on Windows machines when using a non-windows compiler. If the compiler you are using is something like cygwin then the information in the file will contain cygwin style paths (/cygdrive/c/mypath/myfile.c). But Eclipse uses windows paths. It can handle forward slashes instead of backslashes, but will no nothing about /cygdrive/c. So Eclipse supports path mappings which allow you to say things like /cygdrive/c really maps to C:. > I just remembered you're working with C++ and not Java. Perhaps the > CDT doesn't use the debugging perspective to do its debugging. The CDT does use the debug perspective. It adds a few views to it specific for C, such as a memory view, disassembly, and registers but is the same old debug perspective. SignatureDale King >> -snip- >> [quoted text clipped - 6 lines] > Are you actually debugging a program? Is the programmed in a paused > state? Yes it works fine (the program is suspended after each execution line), but I don't see the values of the variables.
