C++ source with test program
std::string variables have value "None" when I access them using the Python
scripting API. They only have one child, which also has a value of None. Is
there another way to get the string value, or am I doing something wrong? I
could probably print the string into the terminal and get the result from the
command interpreter, but it would be nice to access the string directly.
I've attached a simple C++ program that demonstrates this.
I'm using LLDB 3.8 compiled from trunk. The program was compiled using clang++
with libc++ (I also tried g++ and -fstandalone-debug switch with similar
results).
import lldb
import os
debugger = lldb.SBDebugger.Create()
debugger.SetAsync(False)
target = debugger.CreateTarget("./test")
target.BreakpointCreateByLocation("test.cpp", 7)
process = target.LaunchSimple([], [], os.getcwd())
thread = process.GetSelectedThread()
frame = thread.GetSelectedFrame()
for var in frame.vars:
if var.name == "a":
print(var.value) # None
debugger.Terminate()
