RE: GDB/ELF/Cygwin source path problem

[Michael Elizabeth Chastain <mec@shout.net>]

Hi Kris,

Try coff_symfile_read in coffread.c or elf_symfile_read in elfread.c.
I thought Cygwin was still a COFF platform but if you say it's ELF,
then elfread.c would read it.

Okay, that mostly rules out the idea that gcc is putting strange
information into the file.

It's not that hard to debug gdb with gdb.  The procedure is:

  % gdb gdb
  (gdb) set prompt [top] 
  [top] set arge myfile.exe
  [top] break elf_symfile_read
  [top] run

I've never done it with insight so I don't know how the gui plays
with this.
