Why does GDB not show values for local variables?
Depending on the support for such cases offered by the debug info format used by the compiler, GDB might not be able to display values for such local variables. If that happens, GDB will print a message like this: No symbol “foo” in current context.
What is the notation for static variables in gdb?
The :: notation is normally used for referring to static variables, since you typically disambiguate uses of local variables in functions by selecting the appropriate frame and using the simple name of the variable. However, you may also use this notation to refer to local variables in frames enclosing the selected frame:
How to add a field to a feature class?
You can use a loop to work through each feature class in the current workspace. That would create a text field called “Name” in each feature class in your current workspace. I would need a bit more information to help with the filling in part.
When do you get the value of an entry string in gdb?
If you append @entry string to a function parameter name you get its value at the time the function got called. If the value is not available an error message is printed. Entry values are available only with some compilers.
How to execute the locals command in gdb?
You can execute the info locals command manually using the GDB Session window in Visual Studio. However it is recommended to use the Locals window to see the values of the local variables in the currently selected stack frame.
How to list all global variables and local variables?
Type info variables to list “All global and static variable names”. Type info locals to list “Local variables of current stack frame” (names and values), including static variables in that function. Type info args to list “Arguments of the current stack frame” (names and values).
What happens when GDB prints a symbolic address?
When GDB prints a symbolic address, it normally prints the closest earlier symbol plus an offset. If that symbol does not uniquely identify the address (for example, it is a name whose scope is a single source file), you may need to disambiguate. One way to do this is with info line, for example `info line *0x4537′.
