All,
I am trying to debug a compiled c++ program with gdb.
When I start gdb it claims the symbols are loaded. When I try to list
the source code I get:
(gdb) list
/home/corinna/src/cygwin/cygwin-1.7.15/cygwin-1.7.15-1/src/cygwin-1.7.15/winsup/cygwin/crt0.c:
No such file or directory.
in
/home/corinna/src/cygwin/cygwin-1.7.15/cygwin-1.7.15-1/src/cygwin-1.7.15/winsup/cygwin/crt0.c
When I try to single step trough the program I get:
(gdb) start
Temporary breakpoint 1 at 0x401173
Starting program: /home/bernd/Test/a.exe
[New Thread 3820.0x8a0]
[New Thread 3820.0x41c]
Temporary breakpoint 1, 0x00401173 in main ()
(gdb) next
Single stepping until exit from function main,
which has no line number information.
0x004011c2 in _fu0___ZSt4cout ()
Does anybody has an idea what is going on?
I am using
CYGWIN_NT-5.1 ny015GZVTL1 1.7.16(0.262/5/3) 2012-07-20 22:55 i686 Cygwin
GNU gdb (GDB) 7.3.50.20111026-cvs (cygwin-special)
g++ (GCC) 4.5.3
ln (GNU coreutils) 8.15
Thank you for any help.

Sure looks like your program is not compiled with debugging information, i.e., "gcc -g" was not used when compiling and linking the program.

Except I'm written with one r and two n, I'm larger and skinnier in proportion, have different hair, eye, and skin color, rather doubtful actor skills, and I'm probably paid a teeny little bit less for my job. But otherwise, yes, that's me.

That was embarrassingly the case. Now to the root of my confusion: Autotools used to generate a stripped and a debug version. I could run the debugger: gdb .lib/a.exe and the debug information were there. That seems to fail now. The generated Makefile has a line that is commented: #am__append_1 = -Wall -Wextra -ggdb -O0 am__append_2 = -O2 Could that have anything to do with my missing debug information? Anybody else stumbled across this issue?

Definitely. I suggest reading the `info gcc' pages. They explain all the options, including the -g debugging options.
