"backq" Definition

The IPX drivers use a backq system call. Due to a bug in the IRIX 5.3 operating system, the kernel did not define this system call. If you do not define backq, the TotalNET IPX/SPX (tnipx) drivers fail to load and you may see one of these errors:

WARNING: /var/opt/totalnet/nw: symbol backq not found

or

Error loading module tnipx_: Can't resolve all symbols in object

Remedy this by adding backq to the run-time symbol table, as follows:

1. Log in as root.

2. Find the file /var/sysgen/master.d/rtsymtab. Look for a section beginning with this text:

   rtsymtab rtsymtab[] = {

   This line signals the beginning of the section that defines the run-time symbol table.

3. Within this section, look for a line beginning with the following comment:

   /* from sys/stream.h */

   The lines that follow this comment define symbols from the sys/stream.h header file.

4. Add the following line:

   {(long) &backq, "backq"},

5. Save and quit the file.

6. Make a copy of the current kernel:

   # cp /unix /unix.orig

7. Reconfigure the operating system using the following command:

   # /etc/autoconfig

8. Reboot the UNIX server.
