On CentOS 7.6 it is impossible to compile Kannel right now.
According to google results this has been going on for some time with
no real solution available online.
Two solutions have been offered;
1. Install Bison
2. Install Bison < 3
I've tried both, installing Bison 3.0.4 which is the latest version in
CentOS 7 repos.
And removing that, replacing it with a custom compile of Bison 2.7.1
from the GNU FTP servers.
I get the same error when running make using both configurations;
gcc -std=gnu99 -D_REENTRANT=1 -I. -Igw -g -O2 -D_XOPEN_SOURCE=600
-D_BSD_SOURCE -D_DEFAULT_SOURCE -D_LARGE_FILES= -I/usr/include/libxml2
-I/usr/pgsql-11/include -o wmlscript/wsgram.o -c wmlscript/wsgram.c

I ran configure with ./configure --prefix=/var/opt/kannel --with-pgsql
--with-pgsql-dir=/usr/pgsql-11
I've installed bison 2.7 into /usr/local but I've also tried running
LDFLAGS=/usr/local/lib make.
