Zaptel 1.2.15, Asterisk 1.2.16 on Slackware 11.0 box and kernel 2.6.17.13
Zaptel compiled and installed without errors.
To get Asterisk to compile, I had to add:
#include <linux/compiler.h>
above this line:
#include <linux/ixjuser.h>
in chan_phone.c. I have no idea why or what that does… I just found that solution to my error by searching online and it does the trick… Asterisk compiled and installed after that.
However when I try to load the zaptel module I get the following.
FATAL: Error inserting zaptel (/lib/modules/2.6.17.13/misc/zaptel.ko): Invalid module format
I see by searching that this can be caused by having a version of gcc installed which is different from what was used to compile the kernel, but this does not seem to be the case here:
gcc -v

cat /proc/version

Can anyone help me out here?

Do you have CONFIG_CRC_CCITT=y or CONFIG_CRC_CCITT=m in your kernel?
In the Zaptel 1.2.15 README it has the following, although not the exact, but similar error:
[code]Q. Zaptel compiled with no errors but when I try to modprobe zaptel I
receive "FATAL: Error insering zaptel (/lib/modules/2.6.x.x/misc/zaptel.ko):
Unknown symol in module or unknown parameter (see dmesg)
A. You need to recompile your kernel with CONFIG_CRC_CCITT=y or
CONFIG_CRC_CCITT=m. To do this, run ‘make menuconfig’ and change it under
’Library Routines -> CRC-CCIT functions’. If you compiled it as a module,
load it, otherwise reboot.
[/code]
Hi - thanks for the reply. Yes it is there as a module in my kernel, and a:
modprobe crc_ccitt
returns no errors. Howver, even after that I get:
modprobe zaptel
FATAL: Error inserting zaptel (/lib/modules/2.6.17.13/misc/zaptel.ko): Invalid module format
Does anyone else have an idea?
Did you build zaptel for a 2.6 kernel? (making sure the linux symlink points to the correct kernel)
i.e. make linux26
make install
“make linux26” in zaptel 1.2.15 results in a “no target found” error.
in addition to the previous posts, i would suggest checking for multiple installations of zaptel modules. i’ve seen them “move” with kernel changes, and you may well be attempting to load modules compiled for a previous kernel. strip out the old stuff, start fresh.
@batrams
have you resolve this issue?
No, I’ve checked for other versions of the module and anything else I could think of but still get that same error 
I’m gonna try a fresh install of Slackware I think unless someone else can help me?
what’s your kernel version ?
opps … just saw that in the OP … ignore me
