Thank you very much for instructions. I could reproduce what you see. Unfortunately I do not have much to suggest.
dlv expects executable to be written in Go. dlv searches executable for particular symbols (among many other things). That is why you see "could not get Go symbols no runtime.pclntab symbol found" message. So that leaves you with gdb. If you add -g flag to your both gcc and g++ commands, that will include dwarf info. Then you can use gdb: c:\Users\Alex\dev\src\alain_mellan>gdb dload.exe GNU gdb (GDB) 7.7.50.20140303-cvs Copyright (C) 2014 Free Software Foundation, Inc.

Maybe Delve Team might have suggestions. Sorry it took me a while to get back to you. Alex -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
