The problem may be with the application, as "chdir" failed, not with the
gdb.

Gdbserver does not support Solaris.

RE: Problem using gdbserver

[Niu Liang-yong-A16450]

When I want to debug a file, but things happen:

GNU gdb 5.0
Copyright 2000 Free Software Foundation, Inc.
GDB is free software, covered by the GNU General Public License, and you are
welcome to change it and/or distribute copies of it under certain conditions.
Type "show copying" to see the conditions.
There is absolutely no warranty for GDB.  Type "show warranty" for details.
This GDB was configured as "sparc-sun-solaris2.7".
(gdb) file filegen
Reading symbols from filegen...done.
(gdb) run
Starting program: /home/a16450/filegen/filegen 
chdir: Too many arguments.

Program exited with code 01.
You can't do that without a process to debug.


I need your help

Re: Problem using gdbserver

The problem is solved by using the command "(gdb) file <executable-name>"
instead of "(gdb) symbol-file <executable-name>" and by interchanging the
order of execution of this command and "(gdb) target remote
107.108.3.197:2020"

Problem using gdbserver

[Balarama Krishna]

Hi,

The set up for GDB as remote debugger (target=arm-linux, host=i386) is
successful.
The following is my sample test program "test.c"
/******************************************************/
#include <stdio.h>
int main()
{
        int i;
        printf("Hello World \n");
        for(i=0; i<3; i++)
                printf("Checking counter %d \n", i);
        return 0;
}
/***************************************************/

I compiled the above program using arm-linux-gcc with -g option and kept in
the target.
These are the following snap shots while debugging this program

/********************************* TARGET*********************** *****/

The program no longer exists.
(gdb)

/***************************************************************************

I don't know why things are going wrong. Am I missing some thing?? One can
observe that "Hello World" is printed seperately on the Target. Any kind of
help is appreciated in this regard.

Thanks & Regards,
Balaram.
