app_fax compilation failed

hi all,

I’m facing big troubles to make the fax working correctly. I have already send a support request because fax sending wasn’t working with Asterisk-Iaxmodem-Hylafax. I get stuck in “No carrier detected”.
Still investigating I’ve run the asterisk compilation again and I’ve got the following:

[venus -root] pwd
[venus -root] /usr/src/asterisk/asterisk-
[venus -root] make
app_fax.c: In function transmit_audio:
app_fax.c:337: error: fax_state_t has no member named t30_state
app_fax.c: In function transmit_t38:
app_fax.c:517: error: t38_terminal_state_t has no member named t3_state
app_fax.c:518: error: t38_terminal_state_t has no member named t38
make[1]: *** [app_fax.o] Error 1
make: *** [apps] Error 2

As you can see “app_fax.c” can not be compiled.

In the iaxmodem README :

The spandsp source is spandsp-0.0.5 snapshot 20080725

Could you please help on this case.
