Looking at src/port/pg_strong_random.c this would be a bug in autoconf
#else
/* The autoconf script should not have allowed this */
#error no source of random numbers configured
My configure line is:
./configure --prefix=/usr/local/pgsql/10 --enable-debug --with-python
--with-openssl --with-libraries=/usr/local/opt/openssl/lib
--with-includes=/usr/local/opt/openssl/include/ --no-create --no-recursion
I am using openssl-1.0.2j
