how can I put a breakpoint on "something is printed to the terminal" in gdb?
I would like to know from where inside a huge application a certain message is printed. The application is so big and old that it uses all conceivable ways of printing text to the terminal; for example printf(), fprintf(stdout, ...) etc. I write to put a breakpoint on the write() system call but then I'm flooded with too many breakpoint...

GDB structure output
I haven't worked with gdb for a long time and this feels like a basic question. I am trying to observe a structure as it changes but rather than break at a specific point and print it out I'd rather let the application run as normal and give me a snapshot of the structure at a specific point. Think a breakpoint that performs an action ...
How do I find out where an object was instanciated using gdb?
I'm debugging an application and it segfaults at a position where it is almost impossible to determine which of the many instances causes the segfault. I figured that if I'm able to resolve the position at which the object is created, I will know which instance is causing the problem and resolve the bug. To be able to retrieve this inf...

Instruct GDB 6.5 to use source embedded in object file
Hi All! I've been trying to make GNU gdb 6.5-14 to use the source code embedded on the object file when debugging, instead of scanning some directories for it. The main reason is that I develop for an embedded platform and I cross compile, which means that all the source is in my computer. I read about the -ggdb3 flag, that includes a...
How do I get gdb working with D programs under linux?

Debugging a Static Library with the Eclipse CDT
I'm working on getting set with Eclipse CDT for some embedded development and I'm having difficulty getting source level debugging working for static libraries.
