nfs.c not linking

[Ben Dart]

So After the last advice I have checked the following:

1. I am compiling with --enable-networking
2. There is currently no way for us to upgrade to 4.10
3. I have added the following to shellconfig.c as per the instructions here https://docs.rtems.org/releases/rtemsdocs-4.9.2/share/rtems/html/shell/shell00038.html
	#ifdef RTEMS_NETWORKING
  		#define CONFIGURE_SHELL_MOUNT_TFTP
  		#define CONFIGURE_SHELL_MOUNT_FTP
  		#define CONFIGURE_SHELL_MOUNT_NFS
	#endif

This causes the array rtems_shell_Mount_filesystems to look like this:
	rtems_shell_filesystems_t *rtems_shell_Mount_filesystems[] = {
		&rtems_shell_Mount_TFTP,
		&rtems_shell_Mount_FTP,
		&rtems_shell_Mount_NFS,
		NULL
   	 };

All of this is desired.

When I build this I get the linking error, 

1>../../../../../adept_5200/lib\librtemscpu.a(libshell_a-main_mount_nfs.o): In function `rtems_shell_nfs_mounter':
1>d:\Subversion\rtems49\Trunk\build_5200\powerpc-rtems4.9\c\adept_5200\cpukit\libmisc/../../../../../../rtems-4.9.2/c/src/../../cpukit/libmisc/shell/main_mount_nfs.c:46: undefined reference to `rpcUdpInit'
1>d:\Subversion\rtems49\Trunk\build_5200\powerpc-rtems4.9\c\adept_5200\cpukit\libmisc/../../../../../../rtems-4.9.2/c/src/../../cpukit/libmisc/shell/main_mount_nfs.c:51: undefined reference to `nfsInit'
1>d:\Subversion\rtems49\Trunk\build_5200\powerpc-rtems4.9\c\adept_5200\cpukit\libmisc/../../../../../../rtems-4.9.2/c/src/../../cpukit/libmisc/shell/main_mount_nfs.c:58: undefined reference to `nfsMount'
1>../../../../../adept_5200/lib\librtemscpu.a(dummy.o):(.data+0x10): undefined reference to `main'

Important parts are these:

In function `rtems_shell_nfs_mounter':
	main_mount_nfs.c:46: undefined reference to `rpcUdpInit'
	main_mount_nfs.c:51: undefined reference to `nfsInit'
	main_mount_nfs.c:58: undefined reference to `nfsMount'

To me this indicates that nfs.c is not being correctly linked to this file? Has there been a bug that describes this behavior? Was anyone ever able to use `mount -t nfs` in 4.9.2? 

There is a similar bug reported here: http://www.aps.anl.gov/epics/tech-talk/2012/msg01030.php?format=printer 
But this is for 4.10 and I checked the nfs.c and other files and there are no static declarations of these files. 

Is there definitely nothing else I need to do to get this working? No additions to make files to link these together correctly? Or any compiler directives? 

Thanks again for your help.

Ben

+1 this is old.

Shellconfig.h is the way to configure the SRT of commands in the shell.
