Building Kannel 1.4.5 under CentOS 7.5
Well, it’s been a few years since I’ve had to build Kannel (see Compiling Kannel under CentOS 7.0), and a server migration required that I figure it out again.
You can find discussions on why Bison v.3.0 or later, standard with modern versions of Linux, prevents compilation from succeeding. Some discussions provide workarounds that I couldn’t make work.
Here’s how I downgraded Bison and built a working Kannel 1.4.5 binary on CentOS 7.5:
$ cd /usr/local/kannel
$ wget --no-check-certificate https://redmine.kannel.org/attachments/download/322/gateway-1.4.5.tar.gz
$ tar xzvf gateway-1.4.5.tar.gz
$ cd gateway-1.4.5
$ sudo yum downgrade bison
$ sudo ./configure --prefix=/usr/local/kannel --disable-wap --enable-start-stop-daemon
$ sudo make
$ sudo make install
In that downgrade step, Bison was rolled back to version 2.7-4.el7. If you’re doing this at some indeterminate time in the future, the downgrade may be to a 3.x version, in which case you’ll want to downgrade until you’re at a 2.7.x version (also, if you’re at some indeterminate time in the future, simply check your watch and it will be roughly determinate again).
