[lldb-dev] How to set source line breakpoint using BreakpointCreateByLocation?

[Jeffrey Tan via lldb-dev]

Hi,

I am writing a python script to set source line breakpoint in ObjC on Mac
OSX.
But self.debugger.GetSelectedTarget().BreakpointCreateByLocation("EATAnimatedView.m",
line) always fail. Any ideas?

Also, can I use full path instead of file basename? In lldb, I found "b
/Users/jeffreytan/fbsource/fbobjc/Apps/Internal/MPKEats/MPKEats/View/EATAnimatedView.m:21"
will fail to bind but "b EATAnimatedView.m:21" will succeed.
