[lldb-dev] Help RE: help for lldb command like gdb info sources & info source

[Enrico Granata]

Hi Yin,

it looks like you have an older version of LLDB
In order to make the “print >>result, …” syntax work, in ToT LLDB, there is a Python method write() implemented on the class SBCommandReturnObject
That function is probably not there in your version of LLDB

If you can, you could download open source ToT and build it yourself. Then, everything should work
Failing that, an alternative is to replace the print >> result, “foo" idiom with either just print “foo” or you could try one of result.PutCString(“foo”) / result.AppendMessage(“foo”) [1]

[1] unfortunately I can’t recall which one(s) was(were) available in LLDB-179, so you might have to give it a try
