[top] [toc]. Setting a breakpoint on a C++ function is similar to setting a breakpoint on a C function. However C++ is polymorphic, so you must tell break which version of the function you want to break on (even if there is only one). To do this, you tell it the list of argument types. (gdb) break TestClass::testFunc(int) Breakpoint 1
From man gdb(1): -x file Execute GDB commands from file file. You could then put your breakpoints in a file: break [file:]function break [file:]function . Also, you can easily add the project-specific .gdbinit file to your source control, which means that all of your team members can utilize the same debugging

Setting breakpoints. Breakpoints are set with the break command (abbreviated b ). The debugger convenience variable `$bpnum' records the number of the breakpoint you've set most recently; see section Convenience variables, for a discussion of what you can do with convenience variables. You have several ways to say
22 Mar 2009 Setting breakpoints. Breakpoints can be used to stop the program run in the middle, at a designated point. The simplest way is the command “break." This sets a breakpoint at a specified file-line pair: (gdb) break file1.c:6. This sets a breakpoint at line 6, of file1.c. Now, if the program ever reaches that
5.1.2 Setting Watchpoints If the command includes a [thread thread-id ] argument, GDB breaks only when the thread identified by thread-id changes the value of expr . Currently, the awatch and rwatch commands can only set hardware watchpoints, because accesses to data that don't change the value of the watched
You can set breakpoints with the break command and its variants (see Setting Breakpoints), to specify the place where your program should stop by line number, function you can manage a watchpoint like any other breakpoint: you enable, disable, and delete both breakpoints and watchpoints using the same commands.
It is also possible to insert a breakpoint that will stop the program only if a specific thread (see Thread-Specific Breakpoints) or a specific task (see Ada Tasks) hits that . GDB provides some additional commands for controlling what happens when the ' break ' command cannot resolve breakpoint address specification to an
A second way of setting breakpoints is with a line number. The line number refers to the file GDB is currently in. Right now, we're in main.c, so line numbers are with respect to that file for now. Let's set a breakpoint at line 9, where the printf() statement is. (gdb) break 9 Breakpoint 2 at 0x804846b: file main.c, line 9. (gdb).
Use help to get information about available commands. Run program with run command (gdb) run Starting program: gdbprog Program received signal SIGSEGV, Segmentation fault. 0x2350 in DoOperation (ptrs=0x18bc0) at gdbprog.cc:24 24 sum += *ptrs[i];; Program will run until termination, a break point is reached, or an
