Need help compiling ztdummy on a SMP

Asterisk Asterisk Support
1

Preamble - I’m trying to get the ztdummy driver compiled and installed on a hosted gridserver. I’ve already got Asterisk 1.4.21.1 and FreePBX 2.4 up and running on the machine. Everything (for the most part) works fine - SIP clients, calling land lines via our SIP trunk, voicemail, call parking, MOH, etc. Asterisk itself was installed via RPMs

The last piece of the puzzle I want to get up and running is call conferencing. The Linux system I’m using does NOT have the ztdummy drivers installed. I tried installing the Zaptel drivers for it via RPM, but it does not have it. I’ve tried to compile the Zaptel drivers from source but I’m hitting a road block - lots of warnings and a compile error (see below). Any help would be much appreciated!

Output from uname -a:

[root@GSC zaptel-1.4.11]# uname -a
Linux GSC 2.6.18-xenU #2 SMP Mon Feb 11 16:59:22 PST 2008 x86_64 x86_64 x86_64 GNU/Linux

Output from make (I used make menuconfig to select only the ztdummy drivers to be built):

In searcing here, I also saw that zaprtc could also be used - should I try to use this driver?

Thanks.
