Xcode where is gdbinit

You can, instead, specify a process ID as a second argument, if you want to debug a running process:. Taking advantage of the second command-line argument requires a fairly complete operating system; when you use GDB as a remote debugger attached to a bare board, there may not be any notion of "process", and there is often no way to get a core dump. GDB will warn you if it is unable to attach or to read core dumps. You can optionally have gdb pass any arguments after the executable file to the inferior using --args.

This option stops option processing. You can run gdb without printing the front material, which describes GDB's non-warranty, by specifying -silent :. You can further control how GDB starts up by using command-line options. Looking around my Mac, I see that library just fine, and it looks sane. Have you tried using dtrace to see what Xcode and GDB are trying to do when the error happens? Mike G. The library is there on mine too, no file integrity issue if I delete gdbinit, Xcode debugging fully works — ninendra.

You should now be getting compiler warnings for most things you can do wrong in code and the compiler won't let you run the code until you fix them.

When things do get past the compiler's nose, you should be able to find the problem easily with GDB breaking at a convenient spot. These are environment variables that are very handy for early breaking on bad memory allocation or access situations.

If you're on GDB, the syntax to refer to the first argument depends on the calling conventions of the architecture you're running on. If you're debugging on an actual iOS device, the pointer to the object is in register r0. To print it or send messages to it, use the following simple syntax:. On the iPhone Simulator, all function arguments are passed on the stack, so the syntax is considerably more horrible. To make things less painful, I suggest using a convenience variable:.

Note that in all cases I tested, the exception object was also present in the eax and edx registers at the time the breakpoint hit. I'm not sure that'll always be the case, though.

Use i for simulator builds, and use either armv6 or armv7 for device builds - note that some other devices cannot run armv7 code, so usually when building libraries it's a good idea to build all of these architectures and then glue them together using lipo.

You don't have to use all of them, but it's probably a good idea to be clear about what you are building - otherwise I believe your last settings are used. In every case on this Mac I am not able to get source files to be displayed when the debugger stops at a breakpoint. And I have also tried running test unit tests for this project with Xcode It also does not work.
