Makefile Error

We will now ask you a number of questions. You can just press ENTER to accept the defaults!


In what directory do you want to install UnrealIRCd?
(Note: UnrealIRCd 5 will need to be installed somewhere.
 If this directory does not exist it will be created.)
[/home/ubuntu/unrealircd] ->

What should the default permissions for your configuration files be? (Set this to 0 to disable)
It is strongly recommended that you use 0600 to prevent unwanted reading of the file
[0600] ->

If you want, you can manually enter the path to OpenSSL/LibreSSL here.
In most cases you can leave this blank and it will be detected automatically.
[] ->

Do you want to enable remote includes?
This allows stuff like this in your configuration file:
include "https://www.somesite.org/files/opers.conf";
[Yes] ->

Do you want me to automatically download and install curl for you?
[Yes] ->

Do you want to enable prefixes for chanadmin and chanowner?
This will give +a the & prefix and ~ for +q (just like +o is @)
Supported by the major clients (mIRC, xchat, epic, eggdrop, Klient,
PJIRC, irssi, CGI:IRC, etc.)
This feature should be enabled/disabled network-wide.
[Yes] ->

How far back do you want to keep the nickname history?
[2000] ->


What is the maximum number of sockets (and file descriptors) that
UnrealIRCd may use?
It is recommended to leave this at the default setting 'auto',
which at present results in a limit of up to 16384, depending on
the system. When you boot UnrealIRCd later you will always see
the effective limit.
[auto] ->

Would you like to pass any custom parameters to configure?
Most people don't need this and can just press ENTER.
Otherwise, see `./configure --help' and write them here:
