GDB: The GNU Project Debugger
GDB, the GNU Project debugger, allows you to see what is going on `inside' another program while it executes -- or what another program was doing at the moment it crashed.

However, if you would like to try a version of gdb drawn from the most recent release branch, they are also available. ... If you already have a read-only copy of git on hand then there is no need to re-check out a source tree. Instead, you can edit your .git/config to change the remote to ...

GDB "no source available"
You tried to step inside printf() (the clue is where it says "at printf.c: 28"). It's complaining that it doesn't have the source code for printf itself. Probably you want "next" instead of "step" to run printf completely and break after the printf instead of trying to break inside printf. (gdb) help step Step program until it reaches a different source line. Usage: step [N] Argument N means step N times (or till program stops for another reason). (gdb) help next Step program, proceeding through subroutine calls. Usage: next [N] Unlike "step", if the current source line calls a subroutine, this command does not enter the subroutine, but instead steps over the call, in effect treating it as a single source line. Since it's an assembly class, it's possible you're meant to debug printf assembly code. If that is the case, try "layout next" or "layout asm". This will show you an assembly language view. (gdb) help layout Change the layout of windows. Usage: layout prev | next | LAYOUT-NAME Layout names are: src : Displays source and command windows. asm : Displays disassembly and command windows. split : Displays source, disassembly and command windows. regs : Displays register window. If existing layout is source/command or assembly/command, the register window is displayed. If the source/assembly/command (split) is displayed, the register window is displayed with the window that has current logical focus. More on reddit.com

Debugging with gdb - Examining Source Files
GDB can print parts of your program's source, since the debugging information recorded in the program tells GDB what source files were used to build it. When your program stops, GDB spontaneously prints the line where it stopped. Likewise, when you select a stack frame (see section Selecting ...

I FINALLY found out how to do this in cgdb:
- Press Esc to go to the code window.
- Press Alt-O.
- Scroll down to the source file you want to open and press Enter.
Now you can set breakpoints in this file.

I have the same problem; it's amazing that such a basic function is so obscure. My workaround is to use the file name and function name to set the breakpoint:
b <filename>:<function name>

Without debug symbols, gdb does not know what source to display. Since binary files correspond to assembly, one can always get the debugger to show assembly code in TUI with layout asm.

r/C_Programming on Reddit: GDB "no source available"
April 5, 2024 -
Hey, I'm a Comp Eng student and I've been recently introduced to GDB in my assembly class, and while I think as a tool it has very good practical uses, I seem to be unable to use it properly. My teacher gives us weekly assignments that are based on tests, and for each test passed correctly you score 1 point. Now, when trying to debug with GDB as soon as I get to the "printf("Test"....)" that prints my program's result and compares it to the correct result, the print also appears in the GDB debugger command like (aka where I type), therefore bugging it out and subsequently turning the code screen to "No Source Available". Any help?
