OK, I understand that :)

Problems building jack from svn

Hi,

I've just installed FFADO 2.0 beta6 and compiled JACK from the 0.109.2
source no problem. However, running jackd -d firewire gives me:

firewire ERR: Incompatible libffado version! (libffado 1.999.36-)
cannot load driver module firewire

It's been suggested (FFADO-user list and FFADO install docs) that I
build jack from svn. I get the following though (configure seems fine,
make throws errors):

./configure output:
http://pastebin.com/m78857572

make output:
http://pastebin.com/m346203d6

I'm running Debian Etch (2.6.23-rt1 kernel)

Any help appreciated.

Cheers,

Jim.

What architecture are you building on? Looks like you need to define 
__USE_UNIX98 before including pthread.h. Try this patch:

Index: jack/engine.h
===================================================================
--- jack/engine.h	(revision 2761)
+++ jack/engine.h	(working copy)
 <at>  <at>  -21,6 +21,9  <at>  <at> 
  #ifndef __jack_engine_h__
  #define __jack_engine_h__

+/* For pthread_rwlock_t */
+#define __USE_UNIX98
+
  #include <jack/jack.h>
  #include <jack/internal.h>
  #include <jack/driver_interface.h>

I did see it, I just quoted a part of your post. The kernel should be fine.

OK, want to go hunting? :) Try adding '#define __USE_UNIX98' right above 
'#include <pthread.h>' to these files in jack/: jack.h, thread.h, 
internal.h, port.h, and driver.h. Do it one file at a time to make sure 
you spot the correct one; I'd start with jack.h.

Simple Client example may be not a correct example (broken)

Hello Everybody,

I am trying to understand the simple_client, but I think this example is 
broken.

http://subversion.jackaudio.org/jack/jack2/trunk/jackmp/example-clients/simple_client.c 

I am seeing that

/* a simple state machine for this client */
volatile enum {
    Init,
    Run,
    Exit
} client_state = Init;

So that means client_state is initialised to "Init". So far so good.

At the end we wait for the state to have changed ;

while (client_state != Exit) {
#ifdef WIN32
  Sleep(1000);
#else
 sleep (1);
#endif
}

However, never in the program is client_state referenced or changed to 
Exit or any other state.

Yep, I'm up for a bit of hackery :) Can't do this right now but will try
this evening hopefully. Thanks again.

I think that hwmon is not working for me. The details are below but the error i experience is copied here to
