"No symbol table is loaded." when ddd is remote debugging with gdbserver
 

I want to use ddd for remote debugging with gdbserver.

I compile the program uintstr.cpp with "-g" option.

I start the program on the target.
$ gdbserver 172.20.11.211:10000 uintstr
Process uintstr created; pid = 8241


Then I start ddd on the host at the directory which has the source files.
$ ddd
(gdb) target remote 172.20.11.101:10000 uintstr

target display this message on the shell which mean the debug session is setup properly:
Remote debugging using 172.20.11.211:10000

At the host, I do:
(gdb) b main
(gdb) No symbol table is loaded. Use the "file" command.

Why "No symbol table is loaded"?
My PATH environment variable contains the current directory.

(gdb) cont
Program exited normally.

target display this message:
Killing inferior

$ gdbserver 172.20.11.211:10000 uintstr_pause
Process uintstr_pause created; pid = 8223
Remote debugging using 172.20.11.211:10000
sn 9001004 str 9001004

Child exited with retcode = 0

Child exited with status 0
GDBserver exiting


ddd version is 3.3.1 and gdb is 5.0rh-15.

I came across the same problem...
First you have to load the symbols with:
(gdb) file uintstr


Good luck!
