Installing Kannel SMS gateway1.5.0 on Ubuntu 20.04.1

Question

I was able to compiled the gateway but I got the error below running the make command.

Answer 1

This error comes when you're compiling with mysql 8

To fix this, add these lines to gwlib/dbpool_mysql.c

/* define my_bool for newer versions because they use the bool or int C type instead */
#if MYSQL_VERSION_ID >= 80000 && !defined(MARIADB_BASE_VERSION)
typedef bool my_bool;
#endif
