Re: missing text segment in Elf dump

["Lucy Zhang" <lucyz at uclink4 dot berkeley dot edu>]

Can you elaborate on how GDB gets it from the application? and by
application do you mean the executable file?
Also, when I try to look at the source code using "list", does this have
anything to do with the text segment? I ask because it would work for some
source files and not for others. i.e.
(gdb) list condvar.c:88
83      condvar.c: No such file or directory.
          in condvar.c

thank you,
Lucy
