Hey Jeremy,

I filed a bug report with a bunch of info from a debug run that demonstrated this. I haven't heard anything back yet tho.

The linker mauled the debug info - in particular it removed the marker that tells the debugger that the source file switched back from an header file to the main source file. Your bug is sitting with cc tools. This usually happens when the linker has to coalesce functions among various .o files - for instance resolve multiple instances of methods defined in header files down to one copy. Sometimes it removes bits of the debug information along with the stuff it should remove. For reasons that are not quite clear yet, this seems to be happening more frequently of late.

As a possible work around, I find that sometimes if I shuffle the link order of the files around I can sometimes debug into a function that I couldn't before.

Yeah, you probably made the copy that was getting stripped (and thus corrupting the debug info) into the "winning" copy, so it doesn't get stripped...

It's hard to pull yourself up by your bootstraps if your feet are bare.

Apparently this is not just a objective C or framework problem as it happens in my pure C code as well. I step into the function and instead of opening the source file it opens memory.h or some other inappropriate source file. This is on an intel iMac with 10.4.4. Xcode 2.2.1

Is this a known bug?

No takers on this eh?

BTW, this happens regardless of whether I attempt to debug from the app's project or the from the framework's project (setting the app up as the executable).

Also, I'm building into a common build directory.

Thanx for any help!

Hey all,

I'm having problems with the debugger in XCode refusing to show the correct source file when I step into a framework. The source is a .mm file containing the method definitions of a C++ class. Instead it shows the declaration of a parent class in a header file. The Variable pane correctly shows the variables for the method that it should be stepping through however, so I know the debugging info is there. And when I step, it steps correctly as if the correct source file was being shown (i.e. the pointer moves the correct number of lines) but continues to display the wrong file.

Is this a known issue with objective-c++ debugging? Is there a way to tell xcode which source file I want to display? I seem to remember some gdb command that does that but I can't remember what.

Thanx,

Jason
