From 05e306d8d333b56c30bc322983527d2bae771361 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 9 Sep 2017 23:39:07 +0200 Subject: [PATCH] package/asterisk: new package Asterisk: the flagship of telephony on Linux. These are the lines of code whose continuous mission is to power small and large enterprises telephony systems, to boldly provide IP PBX where no one has done so before. But it is a hell to get compiled... :-( For starters, it needs a host tool, menuselect, to prepare its build configuration. Unfortunately, the way it handles menuselect does not apply very well for cross-compilation: the main ./configure calls out to menuselect's own ./configure, and of course that runs with the same environement, which is wrong for cross-compilation (because of variables like CC, CFLAGS and the likes). Furthermore, the paths to menuselect are imbricated about everywhere in the main Makefile, so making it find menuselect in PATH is a lost cause. Instead, we just patch-out the handling of menuselect, build it as the host variant and copy it in place. Now, asterisk wants to install a default set of sound files (for answering machine stuff, I guess). They come come pre-bundled in the official archive [0], but the buildsystem will want to download (at install time) the sha1 files for each sound archive, to validate that said archive is correct. However, the download is done via plain http, so it still risks an MITM attack. And for Buildroot, it is not always possible to download at install time, so we patch-out the sha1 check. [0] http://downloads.asterisk.org/pub/telephony/asterisk/releases/ The official archive contains the sound archives plus a full set of documentation. This makes it very big. Unfortunately, the hosting site is rather slow, topping at about ~204kbps. So we get the archive from the official mirror on Github. But that archive is missing the sound archives, so we download them separately. Some tests, like the crypt() one, are broken and could not have ever possibly worked at all. Worse, the FFmpeg test is looking for headers that FFmpeg removed more than 10 years ago and are virtually no longer available in any distro. So, FFmpeg support is definitely not tested by upstream and can't possibly work at all. Finally, trying to run test-code does not work in cross-compilation. As a final stroke of genius, asterisk checks for the re-entrant variant of res_ninit(), and concludes that all such functions are available, including res_nsearch(). Uclibc-ng has the former but not the latter, so the build fails. Since there is no cache variable for that check, we can't pre-feed that result to configure, and fixing it is a bigger endeavour. So we make asterisk depend on glibc for now, until someone is brave enough to fix it. Almost all features are disabled for now. Support for additional features will be added in subsequent patches now that we have a working base. Signed-off-by: "Yann E.
