Hi everyone.

We have an Asterisk server running Debian Squeeze, with Asterisk v1.8.13.1 (basically, the Debian Stable version for Squeeze, but with some minor source code changes specific to our site). We’re trying to upgrade to 11.13.1 (The Debian Stable version for Jessie), but I’ve run into a snag when compiling res_fax_spandsp (and yes, we really need that module). The old version has been working, and was compiled on this same machine with this same operating system. This is the error I get when doing the make:

[CC] res_fax_spandsp.c -> res_fax_spandsp.o res_fax_spandsp.c: In function ‘spandsp_v21_new’:
res_fax_spandsp.c:487:52: error:
‘MODEM_CONNECT_TONES_FAX_CED_OR_PREAMBLE’ undeclared (first use in this function)
res_fax_spandsp.c:487:52: note: each undeclared identifier is reported only once for each function it appears in res_fax_spandsp.c: In function ‘spandsp_fax_gateway_start’:
res_fax_spandsp.c:819:36: error: ‘t38_gateway_state_t’ has no member named ‘t38’
res_fax_spandsp.c:870:43: error: ‘t38_gateway_state_t’ has no member named ‘t38’
res_fax_spandsp.c:870:83: error: ‘t38_gateway_state_t’ has no member named ‘t38’
make[1]: *** [res_fax_spandsp.o] Error 1
make: *** [res] Error 2

It sounds like I need a library that doesn’t exist on this system, but I
can’t find anything in the includes for this file that would suggest that something is missing.

  • This is defined by spandsp itself in one of its headers. Have you installed the spandsp dev package?

  • Yes, but it’s occurred to me that I’m not using the latest version of the Debian spandsp-dev package.

    However, at the same time, I’m not exactly compiling the latest version of Asterisk 11 either. Is it that big of a deal, or should I try to pin the package from the next version of Debian?

  • The change that started using the define was made on Dec 28, 2011 to improve V.21
    preamble detection. (Git change fdda4947767a5c0ee2424532ff5f01250797175d )
    The spandsp version that compiles on my system is 0.0.6~pre12-1
    Maybe you have remnants of an older version of spandsp still installed.

  • Okay, I’ve gotten it compiled. The problem was that Debian’s version of libspandsp-dev wasn’t the right one. I downloaded and installed the latest version found on spandsp’s website, and the compile went through without any issue.
