[Asterisk-Users] spandsp hylafax asterisk and confusion

I have been attempting to download, compile and configure spandsp to
function with * without much luck.  I am guessing that some assumptions
were made regarding the users knowledge level of Linux.  Sadly,  I must
not live up to those assumptions.  

My problem begins when after compiling spandsp I look for the
app_rxfax.c, app_txfax.c, app_dtmftotext.c and makefile.patch files to
place in the /usr/src/asterisk/apps directory.  I cant seem to find
these files ANYWHERE on my system.  So I then make the assumption that
they were not created by the compile of spandsp nor do they exist in the
source of spandsp.  I did locate these files on the FTP server where I
downloaded the source (I believe it was version J).  Not sure if the
files located on this site were version specific or not I downloaded
them anyway and placed them into the /usr/src/asterisk/apps directory. 
I think I figured out that you need to copy the makefile.patch to the
same directory and run it against the makefile that exists in the apps
directory.  (Never done this before so I might have done the equivalent
of gassing up my car via the radiator)

During the compile of asterisk that is meant to give wonderful new
faxing capabilities,  it dies at app_rxfax.   


So I guess what I am asking,  in a rather long winded newbie way is, 
HELP....  Does anyone have exact  detailed  directions on the procedures
involved in installing spandsp that make no assumptions about knowledge
level?  


Thanks in advance

[Asterisk-Users] spandsp hylafax asterisk and confusion

Hi Terry,

You could have tried following the instructions at 
fttp://www.opencall.org/instructions.html rather than guess how to build 
the software. :-)

If you are using the latest CVS there is a build problem with app_rxfax 
and app_txfax. If you use the latest *stable* CVS it should build OK. If 
you are using version 0.0.1j of spandsp update to 0.0.1k

Regards,
Steve

[Asterisk-Users] spandsp hylafax asterisk and confusion

Thanks for offering to help with this.

I checked out the procedures and attempted this again without success. 



Here is the end of the screen output when the compile fails.

gcc -02 -g  -Include -I ../include -c -o  app_rxfax.o  app_rxfax.c 
app_rxfax.c:45:  error:  'PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP' 
undeclared here (not in a function)
make[1]: *** [app_rxfax.o] error 1
make[1]: leaving directory '/usr/src/asterisk/apps'
make: ***  [subdirs] Error 1




The following is a copy of the modified makefile.  It looks correct as
per your description of what should have been done.

Ah - I remember this.

There may be other fixes, but I resolved this by adding:

#ifndef _GNU_SOURCE
#define _GNU_SOURCE
#endif

Just before the #include <pthread.h> in
asterisk/include/asterisk.lock.h

[Asterisk-Users] spandsp hylafax asterisk and confusion

I actually got mine compiled this morning.. (worked most of the day on
it yesterday).

I made the makefile changes to app_rxfax, app_txfax, and app_dtmftotext
someone in the list recommended, as well as the modification to the
lock.h in the includes directory.  Everything compiles peachy then..

However when I start asterisk...

[app_rxfax.so]May 25 08:43:21 WARNING[1024]: loader.c:240

I can handle the trial and error as far as getting something setup and
compiled, but I think now that I've made it this far it's out of my
hands..  I haven't the slightest on where to start now..

Yes, I'm running CVS-HEAD-05/24/04-16:20:41

[Asterisk-Users] spandsp hylafax asterisk and confusion

Thanks everyone for your responses.  While these tips and tricks did
infact help get asterisk compiled with the fax modules, it seems that *
still craps out on the app_dtmftotext.c when you first start it.  I
can't seem to find a way to get rid of it.  I'm not even totally sure
it's required to send or receive faxes.

If anyone has a step by step (more like, location by location) as a work
around for that, I'd be all ears.

I thought removing the lines in the Makefile for app_dtmftotext.c would
be enough for it to be excluded, but apparently it's not.

If it's this much of a pain to get the fax modules installed everytime I
update from CVS, it makes me wonder if the $8/mo I pay to JFAX isn't
worth it! =)

[Asterisk-Users] spandsp hylafax asterisk and confusion

I appreciate all the support SpanDSP is getting on this list, and the work 
that went into developing it.  It's nice to see that Asterisk actually 
supports sending and receiving faxes now.  

One thing I was expecting to see here is that HylaFax works with SpanDSP, but 
I haven't seen any documentation for this.  Is it possible to use SpanDSP in
conjunction with HylaFax to route the printing and/or emailing of faxes.

[Asterisk-Users] spandsp hylafax asterisk and confusion

Damn! :-(

Now that I have spandsp working on my * I was going to try and get it
working with hylafax.

Is there any other means of faxing from the desktop (windows PC) via
asterisk?

The solution needs to be "user friendly".  I like the solution that
allows the user to "print" from an application (word, notepad,
browser,
terminal session, etc) to a fax driver which in turn connects to the *
server for transmission.  A bonus would be that the faxing application
kept a "directory" of the numbers the user faxed to for easy repeat
faxing.

Any solutions out there like this?

I have a half implemented solution based on salsafax. Basically, you 
have to configure cups and samba to export a printer to the network, 
then you can print from any workstation to the network printer. Pros: 
you do not need any special driver on the workstations. Cons: it does 
not always work.

The problem I found is that there is no reliable way to indicate the fax 
number where the document should be sent. Salsafax extract the 
information from the ps file generated (you have to use a special syntax 
in the document for the fax number), but most of the time salsafax 
fails to decode the text, so it cannot send the fax.

So I tried harder, and modified it to perform and OCR of the document 
and try to extract the number that way. It work 75% of the time. Its 
kind of user friendly, but its not reliable.

I think that the best solution would be to implement a web interfase so 
you can specify the destination numbers from there. 1) You print to the 
fax machine 2) Enter a web page and specify the fax number/s where the 
new document should be sent 3) lets asterisk/spandsp do the job.
