No.  Don't use solib-search-path for this.

Use:
  set solib-absolute-prefix /opt/montavista/pro/devkit/ppc/8xx/target

You are using MontaVista's gdbserver.  You should be using their GDB,
too.  This only works with both.

Hi Daniel,
	Huh!  I set solib-absolute-prefix
/opt/montavista/pro/devkit/ppc/8xx/target and create /mnt/cf/shared/lib
under this path. All library can be loaded successfully. Thank you very
much. But there is another error when I debug the program. When the program
step to the system(), it hang and display "Detaching after fork from child
process 275."

	(gdb) n
95        char bDhcpFail=0;
(gdb) n
100       if (g_profile->ipSetup.ucImode == MODE_STATIC)
(gdb) n
122         sprintf(cRdBuf, "dhcpcd -t 10");
(gdb) n
123         rc = system(cRdBuf);
(gdb) n
Detaching after fork from child process 275.
======================================
Waitting for a long time
=======================================
Remote communication error: No route to host.

I use x86 gdb debug the test program which include system call, it didn't
display  "Detaching after fork from child process xxx".

(gdb) n

No.  Don't use solib-search-path for this.

Use:
  set solib-absolute-prefix /opt/montavista/pro/devkit/ppc/8xx/target

You are using MontaVista's gdbserver.  You should be using their GDB, too.
This only works with both.

Hi Daniel,
	Huh!  I set solib-absolute-prefix

much. But there is another error when I debug the program. When the program
step to the system(), it hang and display "Detaching after fork from child

Hi Daniel,
	Huh!  I set solib-absolute-prefix
/opt/montavista/pro/devkit/ppc/8xx/target and create /mnt/cf/shared/lib
under this path. All library can be loaded successfully. Thank you very
much. But there is another error when I debug the program. When the program
step to the system(), it hang and display "Detaching after fork from child
process 275."

	(gdb) n
95        char bDhcpFail=0;
(gdb) n
100       if (g_profile->ipSetup.ucImode == MODE_STATIC)
(gdb) n
122         sprintf(cRdBuf, "dhcpcd -t 10");
(gdb) n
123         rc = system(cRdBuf);
(gdb) n
Detaching after fork from child process 275.
======================================
Waitting for a long time
=======================================
Remote communication error: No route to host.

I use x86 gdb debug the test program which include system call, it didn't
display  "Detaching after fork from child process xxx". 
8               printf("please show me\n");
(gdb) n
please show me
9               system("ls");
(gdb) n
hellogdb  hellogdb.c  makefile
10              return 0;
(gdb) n
11      }

No.  Don't use solib-search-path for this.

Use:
  set solib-absolute-prefix /opt/montavista/pro/devkit/ppc/8xx/target

You are using MontaVista's gdbserver.  You should be using their GDB, too.
This only works with both.

No.  Don't use solib-search-path for this.

Use:
  set solib-absolute-prefix /opt/montavista/pro/devkit/ppc/8xx/target

You are using MontaVista's gdbserver.  You should be using their GDB, too.
This only works with both.

Hi Daniel,
	Huh!  I set solib-absolute-prefix
/opt/montavista/pro/devkit/ppc/8xx/target and create /mnt/cf/shared/lib
under this path. All library can be loaded successfully. Thank you very
much. But there is another error when I debug the program. When the program
step to the system(), it hang and display "Detaching after fork from child
process 275."

	(gdb) n
95        char bDhcpFail=0;
(gdb) n
100       if (g_profile->ipSetup.ucImode == MODE_STATIC)
(gdb) n
122         sprintf(cRdBuf, "dhcpcd -t 10");
(gdb) n
123         rc = system(cRdBuf);
(gdb) n
Detaching after fork from child process 275.
======================================
Waitting for a long time
=======================================
Remote communication error: No route to host.

I use x86 gdb debug the test program which include system call, it didn't
display  "Detaching after fork from child process xxx". 
8               printf("please show me\n");
(gdb) n
please show me
9               system("ls");
(gdb) n
hellogdb  hellogdb.c  makefile
10              return 0;
(gdb) n
11      }

Thx,
Xi
