Asterisk 21.2.0编译安装经常遇到的问题和解决办法之json

本文主要是介绍Asterisk 21.2.0编译安装经常遇到的问题和解决办法之json，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

写在json之前

在讨论jansson之前，我们先来看另外一个问题：

checking for libedit… no
checking for history_init in -ledit… no
configure: error: *** Please install the ‘libedit’ development package.

需要安装libedit。
难道这个没有在 install_prereq 里面吗？
再次测试一下

./contrib/scripts/install_prereq test

提示我需要安装如下的包：

yum install --skip-broken --assumeyes pkgconfig jansson-devel libuuid-devel speex-devel speexdsp-devel libogg-devel libvorbis-devel portaudio-devel xmlstarlet postgresql-devel unixODBC-devel neon-devel gmime-devel uriparser-devel mysql-devel bluez-libs-devel radcli-devel freetds-devel jack-audio-connection-kit-devel libcap-devel net-snmp-devel iksemel-devel corosynclib-devel newt-devel popt-devel libical-devel spandsp-devel libresample-devel uw-imap-devel binutils-devel libsrtp-devel gsm-devel doxygen graphviz hoard codec2-devel fftw-devel libsndfile-devel unbound-devel subversion

还缺不少呢。揣测一下，可能需要反复安装install_prereq，因为有些包可能没安装好。

Asterisk requires libjansson

checking for jansson >= 2.11… no
checking for json_sprintf in -ljansson… no
configure: *** Asterisk requires libjansson >= 2.11 and no system copy was found.
configure: *** Please install the ‘libjansson’ development package or
configure: *** use ‘./configure --with-jansson-bundled’

意思是json没装好。
两个解决办法：

1. 从digip下载源代码编译安装

wget https://digip.org/jansson/releases/jansson-2.13.tar.gz --no-check-certificate
tar -zxvf jansson-2.13.tar.gz
cd jansson-2.13
./configure
make
make install

2. 从asterisk github下载源代码
   先把jansson下载到/tmp目录下
   wget https://raw.githubusercontent.com/asterisk/third-party/master/jansson/2.14/jansson-2.14.tar.bz2
   然后带一个参数给configure

./configure --with-jansson-bundled --with-pjproject-bundled
