step is not working

step is not working

[Jean Paulo Sandri Orengo]

Hi,

   I've just installed insight on my linux and tested it.
   It worked fine when I run the application. But a problem occur every
time  I want to
execute the code step by step. When I visualize the code in "ASSEMBLY",
it works pretty
good, but if I visualize the code in "SOURCE" the program don't run
well. When I press the
button "step" it stays on the same line and don't make any progress!!!
If  I put a
breakpoint (in other line) and press the  button "continue" it works well.
   What is happening with the step button?

PS: using the "console window" the error messages printed are:

(run)

Error while mapping shared library sections:
/lib/tls/libc.so.6: No such file or directory.
Error while mapping shared library sections:
/lib/ld-linux.so.2: No such file or directory

(step)

Error: Warning:
Cannot insert breakpoint -89.
Error accessing memory address 0x28640: Input/output error.

Thanks,
Jean

First thing to try is using command-line only gdb to make sure it works.
The errors you are seeing seems to indicate that there are some serious
problems with your configuration:

Try using gdb (i.e., without the GUI) and see if that works. If it does,
we'll work on figuring out what's up with your setup.

      I've already tried. It has worked well with the same code.

    I'm afraid that the problem is on my configuration...

Were you using the same versions of gdb & insight? (Just curious)

What's the output of "insight -v"? Have you tried a snapshot or CVS
HEAD?

 Versions:

  gdb: GNU gdb 6.3-debian
  insight: GNU gdb 2004-08-11-cvs

PS: All programs were installed from a official debian mirror.

Zowie. That's pretty old. I don't suppose I could convince you to try a
snapshot?

 I've found the libs listed above on the same directory(/libs/ and
/libs/tls/). Why Insight is not finding them?

These are gdb errors. (Gdb is the "backend"; insight is "just" a GUI on
top of gdb.)

You're best bet is to ask on the gdb mailing list.
