debug problem using cygwin [message #140379]

hello.

i am using cdt2.1 with eclipse3.01 and cygwin (gcc, gdb, ..). I've
created a configuration for running a console-application. it works fine
(output appears in the Console-Window).

But if i try to debug it, a popup appears:

"Unable to set temporary breakpoint in main.
target request failed: no symbol table is loaded.
Use the "file" command..
Continue?"

what could be the reason for that? if i choose "Yes" to continue, the
output appears in a little external shell-window. i've compiled using -g3
flag. In the settings i've chosen "Cygwin gdb" as debugger and set "Stop
at main() on startup".

with kind regards,
watzlaw

yes. debugging using command-line gdb works fine. its seems to be cdt
which can not communicate with gdb. other hints?

What's your GDB version.
(You can learn by 'gdb --version')
It must be 5.2.1 at least. 6.3 is preferred.

This also may happen if a wrong executable is passed to gdb. Check the
executable name in the launch configuration dialog.

hi.

it was no cdt-bug, but my nonability to write a makefile: A little
"install -s" stripped all my symbol tables away.

thank you for your friendly and fast help.

with kind regards,
watzlaw wutz
