[mythtv-users] Re: Connection problem

[Don Brett]

I just took a quick look to see what that error was about.  Here's what
I found:

- The connection may be working fine.
- It's doing a check on protocol compatibility before proceeding (a good
thing to do).
- This check throws an error if it doesn't understand the response from
the backend, which is what I would expect if the protocol doesn't match.

It seems that the backend is a different version than what mythweb is
expecting.  And probably different enough that it doesn't even
understand the answer.

Here's the function that's returning the error:

.......
        check_proto_version:
        Check that we are speaking a version of the protocol that is
compatible
*/
    function check_proto_version($fp) {
        global $MYTH_PROTO_VERSION;
        $our_version = $MYTH_PROTO_VERSION;
        $cmd = "MYTH_PROTO_VERSION " . $our_version;
        $response = explode(backend_sep, backend_command2($cmd, $fp));
        if ($response[0] == "ACCEPT")
            return;
        if ($response[0] == "REJECT")
        {
            trigger_error("Incompatible protocol version (mythweb=" .
$our_vers
            return;
        }
        trigger_error("Unexpected response to MYTH_PROTO_VERSION '" .
$cmd . "'
    }

Mythweb is expecting the backend protocol version to be 13.

>From line 15 of mythbackend.php:

.......
// MYTH_PROTO_VERSION is defined in libmyth in
mythtv/libs/libmyth/mythcontext.
// and should be the current MythTV protocol version.
    $MYTH_PROTO_VERSION = "13";
.......

So, looking for mythcontext:
#locate mythcontext

, mine is located on:

/usr/local/include/mythtv/mythcontext.h

, and here's the line from mythcontext.h that defines the version (line
114)

#define MYTH_PROTO_VERSION "13"

So, go look at your mythcontext.h to see what version it is.  Don't know
if this helps, but it might be a good start.  Good luck,
Don
